There is a smell in the well, what to do? Unpleasant water odor: causes and ways to eliminate it

Autonomous water supplyoptimal solution for private households. True, for convenience and safe use required proper arrangement wells or wells.

Even if all installation conditions are met, musty odors often appear. Why does water from a well smell of hydrogen sulfide, what factors influence this process and how to correct the problem?

Reasons for the appearance of hydrogen sulfide compounds

Hydrogen sulfide appears during the decomposition of protein components of the activity of anaerobic bacteria (they develop in an oxygen-free environment). from the well has significant drawback: it is toxic, in large doses it causes severe poisoning of the body or death.

There are many reasons why hydrogen sulfide compounds appear in water:

  • Formation of silt on the walls or bottom of a water source.
  • An increase in the number of bacteria and their metabolic products. This often occurs after heavy rainfall.
  • Violation of tightness, which leads to the leakage of hydrogen sulfide compounds through microcracks.
  • Ingress of sulfur ores during well drilling. In this case, you can feel that the water in the well smells of hydrogen sulfide already in the first hours of operation of the water intake point.
  • Penetration of surface and flood waters saturated with hydrogen sulfide impurities of technical origin into the well column.

Important! Hydrogen sulfide compounds are often found in water obtained from artesian or deep wells. If the liquid contains petroleum products or chloride compounds, this is a sign of technogenic pollution.

To get rid of the smell of hydrogen sulfide when extracting water from a hydraulic structure, it is necessary to ensure its proper treatment.

Hazardous effects of hydrogen sulfide

The hydrogen sulfide smell of well water poses a serious danger to human body. For this reason, liquid with a high content of compounds is unsuitable for drinking, household and technical purposes.

The main reasons why hydrogen sulfide is considered dangerous to humans:

  • This chemical element is a volatile compound, but is present in water in a soluble form. Unpleasant smell may cause dizziness, allergic reaction, fatigue, physical fatigue and vomiting. A high concentration of the element in the air is the main cause of inflammation on the eyelids, fainting and intoxication of the body.
  • Soluble hydrogen sulfide compound can be corrosive to individual metal parts installed devices and units.

To eliminate the smell of hydrogen sulfide in well water, an immediate disinfection procedure will be required.

Available methods for disinfecting water resources

If the water from a well smells of hydrogen sulfide, what should you do in such a situation? This is a logical question that any homeowner will ask. Only correct solution– qualitatively purify the water. There are many affordable ways to do it right by simply installing household disinfection units.

Choice effective way cleaning is based on the result of an analysis of the liquid to identify existing compounds, bacterial and viral organisms.

Before you take more drastic action, you can solve the problem yourself. To achieve this, the following work is carried out:

  • Cleaning the internal walls and bottom of the well string from sulfur deposits. This will help solve the problem for a period of 12 to 36 months.
  • Pumping the water surface to remove clay and sandy parts from the bottom of the well. This helps eliminate most of the sulfur bacteria that are located at the very bottom of the water intake point.
  • Strengthening the tightness of the casing pipe or reinstalling it.

Once the pre-cleaning is complete, you can begin eliminating sulfur odors.

Physical aeration

A simple and popular cleaning method. Special degassers are designed for this purpose:

  • Pressure units are compact devices that provide rapid supply of a small volume of liquid for its active saturation with oxygen using a pump. The device is installed in technical rooms on the ground floor or in the basement.
  • Units without pressure are volumetric structures made of plastic that are not airtight. They are designed to purify water with oxygen that enters through the inlet nozzles. To speed up the removal of residual impurities from the water, it is additionally recommended to install an air compressor blower in the container.

Chemical disinfection

The method involves complete degassing of the water mass, where active components act as an oxidizing agent - hydrogen peroxide, ozone, hypochlorite. The oxidation process leads to the formation of water-insoluble compounds - sulfur, sulfate, thiosulfate, which are contained by special filters during purification.

Chlorine cleaning

After chlorination, colloidal sulfur is formed, which requires additional coagulation, filtration and removal of unpleasant odors. For a private water supply, such a method of water purification cannot be implemented.

Cleansing with ozone and hydrogen peroxide

Ozone quickly cleans, disinfects and decolorizes water, eliminating hydrogen sulfide compounds.

To purify the water mass from a well, you can use ordinary hydrogen peroxide. This method is the most accessible and effective. During the disinfection process, hydrogen sulfide elements are converted into sulfur, and the musty odor is removed using carbon filters.

Cleansing with potassium permanganate

Simple and affordable way degassing water from hydraulic structures - using potassium permanganate (potassium permanganate). It promotes hydrogen sulfide oxidation, which leads to the formation of colloidal sulfur. However, here too there is one significant drawback: potassium permanganate leads to the appearance of salt deposits in the water, which require rapid removal.

For better cleaning with potassium permanganate, it is recommended to use double filters. In this case, the oxidation of hydrogen sulfide compounds produces manganese hydroxide, which is a strong adsorbent substance.

Sorption disinfection

This method involves the use of special sorbents. Such materials make it possible to accelerate oxidative processes in sulfur compounds. The main disadvantage of sorption disinfection is the duration of the procedure.

Active sorbents are natural materials - wood or Activated carbon in granules. They have high catalytic characteristics, which allow you to quickly and safely purify the water mass from any existing impurities.

The appropriate type of sorbent is selected taking into account its functional characteristics - the size and structure of microscopic pores. No less important is the type of oxide elements that are formed as a result of the oxidation process and deposited on the sorbent.

Often the smell of hydrogen sulfide in water after disinfection appears when it is heated. This indicates that there are salt deposits on the heating elements of the boiler, boiler or column, which provide an ideal environment for the development of microorganisms.

Safe purification of water from a well from hydrogen sulfide compounds is a set of measures aimed at eliminating unpleasant odors and restoring normal water parameters. This will provide clean water that can be used for hygienic and domestic needs.

Autonomous water supply complexes make it possible not to depend on centralized water networks. However, the owner must be prepared for the fact that all responsibility for cleaning it and service. The problem often arises of what to do if the water from the well smells of hydrogen sulfide. IN this material Let's figure out what ways you can avoid this, consider methods of filtering from various impurities and unpleasant stench, and how to do this at minimal financial cost.

When constructing a private house, the owner must first take care of quality water supply. In most cases, citizens prefer standalone devices so as not to be dependent on preventative measures and seasonal outages. Even if you have drilled a deep well, this does not mean that the artesian moisture will be crystal clear. It may contain hydrogen sulfide gas, impurities of heavy metals and salt, as a result of which its use becomes dangerous to the health of adults and children.

Causes of a rotten stench

Hydrogen sulfide is a gaseous substance, and when it evaporates, it spreads a stench. rotten eggs. It is created by bacteria, which are the result of the decomposition of protein substances. Bacteria feed on the products of this decomposition, resulting in a rotten, unpleasant stench.

Let's figure out why water from a well smells of hydrogen sulfide? Microorganisms from sulfates and sulfites of this gas multiply most actively in an environment with a minimum amount of oxygen. Foci of infection, as a rule, are the muddy bottom and walls of an untreated well. Also, an unpleasant stench can occur in layers where oxygen access is not provided. This is the reason why a recently drilled deep artesian well smells like rotten eggs.

The highest concentration of microorganisms is observed in the following places:

  • drilling rigs during floods and heavy rains;
  • accumulations of sulfide ores;
  • rusty moisture from the drill hole;
  • industrial drilling regions;
  • loose joints of the well or throat, where moisture seeps in.

In many cities and towns, a musty stench in the water supply is not uncommon, and its harm consists of many negative consequences for the health of people and the safety of equipment and household appliances.

Dangerous consequences of exposure

Let's consider the most dangerous manifestations of exposure to volatile gas:


How to get rid of the stench

It is extremely important for human health and the preservation of household appliances to get rid of the substance. If a home owner is concerned about the health of his family members, he should consider options for what to do if the water from the well smells like a swamp. Clean drinking moisture will be the key to health, and will also allow you to save on repairing plumbing, pipes, and purchasing new household appliances.

The only proven and reliable method of getting rid of the stench of rotten eggs is to install a special device with carbon filters. Its average cost is 3500-4000 rubles.

In addition to volatile gas, there are other impurities in water that enter into chemical reactions with hydrogen sulfide and stimulate corrosion. Chloride and sulfide impurities increase the amount of hydrogen sulfide precipitation. If you suspect dampness and mustiness in your well, we recommend that you submit samples for inspection to the appropriate authority. It is also necessary to install special filters and conduct.

Cleaning methods

The substance evaporates quickly after a long period of settling. However, when supplied through taps, such settling must be carried out before entering the water intake system.

To do this, the following equipment is installed:

  • Gravity aerators are great plastic containers, into which the liquid enters through spray nozzles. It is saturated with oxygen, which does not allow hydrogen sulfide bacteria to multiply. The remaining volatile gas is then completely evaporated, and in order to speed up the process, it is possible to install an oxygen compressor. The non-pressure device is mounted under the roof, and the supply is carried out by gravity;
  • Pressure aerators are designed for a smaller volume. The operating principle of the device is that water is lifted from the bottom of the container by a pump and is actively saturated with oxygen. The device is installed on the ground floor of a private house or in the basement.

Professional drilling is carried out by specialists from the Drilling Company in Nizhny Novgorod at affordable prices.

Chemical method

This method is also based on gas oxidation, but the oxidizing agent is not oxygen, but ozone, hydrogen peroxide or sodium hypochlorite. As a result of oxidation, sulfur, sulfates and thiosulfates appear, which do not dissolve, but are retained by filters with granular fillers, as a result, a purified stream is supplied through the taps.

To install quality cleaning system and drink crystal clear artesian water, you can order from a specialized company that will provide the full range of work and equipment for your home.

Sorption method

This method is based on the property of sorption substances to stimulate oxidative reactions. Activated carbon in granules, characterized by effective catalytic properties, is considered the most productive sorbent. For use this method The water must have a high oxygen content, so it is mainly used in conjunction with pressure units.

Sometimes the hydrogen sulfide stench after filtration appears during the process of passing the liquid through the water heater, as a result of which only boiling water has an unpleasant aroma. The reason for this is salt deposits on the walls of the boiler, where sulfate-reducing microorganisms multiply. To destroy such bacteria, it is necessary to thoroughly rinse the water heater and install a sorbing filter.

If you want to learn how to bring water from a well into a house with your own hands, you should be guided by the following algorithm of actions. First of all, you need to purchase the following units:

  • pumping station;
  • cleaning units of the selected type;
  • water heater with storage tank.

The first stage will be the arrangement of the caisson; it can be made of concrete or brick, or you can purchase a ready-made plastic one. The outside must be waterproofed and a lid must be provided on top. The next step is to install a pump and run pipes from the well into the house. To extend the life of the pump, it is recommended to install a hydraulic accumulator. You also need to install filters of the selected type. You can install the equipment yourself, but we recommend contacting the professionals of the Nizhny Novgorod Drilling Company, who guarantee the quality of the work performed and durability of operation.

So, purification from hydrogen sulfide is carried out not only to eliminate the unpleasant stench, but also to restore the purity of the water. Purification is required to ensure that the liquid is safe for health and does not destroy equipment in the water supply.

If a well has already been made on the site, it’s time to think about the quality of the water coming from it. The quality of this liquid will depend not only on the type of soil, but also on the content of various microelements in it (iron, hydrogen sulfide, etc.). The presence of such microelements in water can cause the appearance of unpleasant odor, which makes it unsuitable for further consumption for food purposes.

Water, due to the presence of various microelements in it, for example, hydrogen sulfide, may have an unpleasant odor and be unsuitable for consumption for food purposes.

Water requirements

Water should not only be tasty, but also safe. Therefore, epidemiological safety requirements apply to it. If the liquid is in a contaminated body of water, then the measures taken to clean and disinfect it will be of great importance. These measures are part of the mandatory set of measures to ensure water supply.

Most often, more thorough measures are used for cleaning surface waters. Here highest value has hydrogen sulfide removal. If this is not done, it will significantly reduce the quality of the water.

This is due to the fact that such gas not only has an unpleasant odor, but can also form acid based on hydrogen sulfide. This acid can destroy not only the pipeline, but also cause significant harm to the human body. The smell of water indicates that it contains the following substances in large quantities:

  1. Iron.
  2. Zinc.
  3. Copper sulfite.

Their increased content is simply unacceptable for food consumption, as it can cause a number of serious diseases. Such untreated water can cause various intestinal infections and even typhoid fever.

If there is an unpleasant odor from the water from the well, it is necessary to analyze it. This control will reduce the likelihood of various infections and the possibility of their spread. For drinking water use, it is necessary to block E. coli by performing comprehensive cleaning measures.

Performing water purification

Most often, all kinds of filters and even entire filter units are used to eliminate odor and further purify the liquid. But most effective methods purification is chlorination and ozonation of water. Potassium permanganate is used for ozonation.

If water supply is organized in a private house, then initially it is necessary to install coarse filters. They will clean the incoming liquid from sand, various suspensions or silt. Silt can form both on the walls of wells and on the walls of wells. Reducing the number of foreign inclusions is the initial step in eliminating odors, because they will be blocked along with hydrogen sulfide acid.

When using a well, at the stage of its preparation, you need to add to the solution liquid glass. This measure will improve the tightness of seam joints. But it's still better to use it groundwater with deep burial, since they have minimal amount harmful inclusions. Therefore, artesian wells are currently very popular.

Liquid from artesian wells is the most preferred option for food use. The depth of such water is more than 50 m. It is purified before it enters the pipeline system. This happens due to the passage of water through a large number of impermeable layers.

If the water coming from an artesian well smells, this may indicate a poor design of the well, since bad smell may appear as a result of the decomposition of organic substances, which subsequently enter the water composition.

Incoming water quality

The quality of the liquid entering the water supply also depends on the content of salts present in it. In central water supply systems, it is mandatory to apply disinfection measures. These measures can be carried out most effectively by adding chlorine to the composition of liquids and further carrying out ozonation.

These measures allow us to eliminate the most unfavorable element - colloidal sulfur. Its presence in water causes large sediment and increased turbidity. If colloidal sulfur is present in the liquid, its further clarification is required using a special contact procedure.

Final cleaning can be accomplished by adding an oxidizing agent to the water composition. The best and least dangerous oxidizing agent is oxygen. Therefore, such oxidation is performed by aeration. To do this, you need to install an aeration column equipped with a static mixer at the outlet.

Refined quality tap water should be tested in a special laboratory. After it has been carried out, you need to obtain a conclusion that will stipulate the possibility of using it for food purposes.

Eliminating odors from drinking liquids is essential to ensuring a healthy diet. And healthy eating is the key to a healthy life.

Often owners of private houses and country cottages notice the appearance of hydrogen sulfide from the smell. There is no point in putting off solving this problem. Such water not only smells bad, but is also dangerous to health. In search of an answer to the question “what to do?” many seek advice from more experienced owners, and also read reviews on thematic forums. As a rule, the recommendations boil down to one thing: the water needs purification. There are several ways to do this.

Where does hydrogen sulfide come from in a well?

Water from a well is convenient and troublesome at the same time. An individual water supply system requires maintenance, cleaning, and sometimes repairs, and all this needs to be done by the well owner. The smell of hydrogen sulfide is a common problem among those who have a personal well on their property. Looking for clean water the owners drill quite deep holes in the ground. However, gas is often found in deep areas. This happens for the following reason: sulfur bacteria, which form over time dangerous substance, live in the absence of oxygen. Very often these are water layers surrounded by waterproof soils (at great depths), or the bottom of neglected wells. As a result of the activity of bacteria, a colorless gas is produced - hydrogen sulfide. It gives the water a terrible smell and the repulsive taste of rotten eggs.

Advice. Pay attention to the silver cutlery. Their blackening may also be a sign of the appearance of hydrogen sulfide in the water.

A high concentration of hydrogen sulfide and activation of sulfur bacteria are usually observed in the following situations:

  • during periods of heavy rain or in the event of floods, when the soil absorbs organic matter along with water from the surface;
  • in case of violation of the casing string tightness. Sulfur compounds in the soil leak inside;
  • if there are deposits of sulfide ores near the well;

Hydrogen sulfide is dangerous to humans

  • when sulfur-containing rocks get inside the well during its construction;
  • if the well is drilled in an industrial region.

Why is it necessary to purify such water? Preparatory stage

It is almost impossible to use a well that smells of hydrogen sulfide. The smell of such water is disgusting, but this is not the most dangerous:

  1. The colorless gas is very toxic. Possessing high degree volatility, it quickly spreads throughout all rooms where hydrogen sulfide water is used. Prolonged inhalation of toxic air leads to poisoning, and its strong concentration can cause coma or respiratory arrest.
  2. Hydrogen sulfide disrupts vital processes in the body. Organs receive less oxygen. A person stops smelling hydrogen sulfide and continues to inhale the toxic substance, accumulating it in the body.
  3. Sulfur compounds harm plants that are watered with such water.
  4. Due to the corrosive activity of hydrogen sulfide, the service life of metal parts of the well, pipes, and plumbing is significantly reduced. All this quickly rusts.

Advice. If there is a risk of hydrogen sulfide appearing in the water, it is better to install plastic pipes.

There are several ways to eliminate toxic substances from a well. A laboratory water analysis will tell you which one to choose. The content and quantity of impurities, bacteria, and viruses will be determined at the sanitary and epidemiological station. The standards establish that the permissible dose of hydrogen sulfide is 0.03 mg/l. Whether this level changes over time can be judged by regular analyzes of samples from the well.

If you notice an unpleasant odor, immediately begin purifying the water.

Proper water intake involves using a bottle from mineral water. Containers from other drinks will not work. The container needs to be rinsed and then filled to the very top with water from the tap, after draining it for 10-15 minutes. It is advisable to deliver the sample for analysis within 2 hours after collection.

Methods for cleaning a well from hydrogen sulfide

Once you receive the test results, you can choose one of the methods for purifying water from hydrogen sulfide.

Treat the well. There are several directions:

  • remove deposits from the bottom and walls;
  • remove sand, silt, clay that has accumulated at the very bottom. After this, you can pour a layer of coarse crushed stone onto the bottom - this will be a natural filter;
  • ensure the tightness of the casing.

Advice. You can do this work alone or invite specialists who drilled the hole to help.

Use the physical method. Since hydrogen sulfide is a volatile substance, it evaporates if water stands in any container (for example, in a bucket). However to modern man It’s more convenient to use the plumbing system than to rush around with vessels. Therefore, it is necessary to settle the water before it goes through the pipes. This can be done with special devices - degassers. They come in two types.

  • A non-pressure tank looks like a plastic tank into which water flows through spray nozzles. In the process, it is saturated with oxygen, which performs 2 functions: suppression of sulfur bacteria and oxidation of hydrogen sulfide. The device is mounted under the roof, water flows out of it by gravity, and for greater effect you can put an oxygen compressor in the tank.

Water purification scheme for a country house

  • The capacity of a pressure degasser is less than that of a non-pressure degasser. The water falls to the bottom of the tank and is enriched with oxygen, which is supplied by the pump. Such a device is installed on the first or basement floor.

Advice. Before aeration, the water can be acidified.

Resort to a chemical method: hydrogen sulfide can be oxidized not with oxygen, but with hydrogen peroxide or ozone, or sodium hypochlorite. In this case, insoluble compounds are retained in the filter, and the gas is neutralized.

Use the sorption-catalytic method. It is most common when autonomously supplying water from a well. A sorbent placed in a filter (activated carbon is best) purifies the water. However, if the level of hydrogen sulfide is very high, the sorption method is combined with the installation of a pressure degasser.

Sometimes, to eliminate hydrogen sulfide, it is not necessary to install special equipment. Instead, iron-removing filters will be able to cope with the harmful gas. It is important to choose the correct dosage of reagents. It also happens that the only thing that smells of hydrogen sulfide is hot water. The reason often lies in salt deposits on heating elements, which are a source of bacteria. In such cases, you need to wash the boiler and install a sorption filter on the pipe.

The main causes of unpleasant odor in water


Thick layers of soil above an aquifer are good filter, trapping most contaminants. But, seeping from the surface through numerous layers, the liquid is saturated with salts and collects many microorganisms with different properties. Therefore, even deep artesian wells cannot guarantee 100% purity of water.

There are even more various impurities in sand wells. Metals, salts, oxides and other compounds make the liquid a chemically active substance, and in certain combinations they change its color, taste, and smell.

In addition, organic matter (algae, land plants) after entering the well, they begin to rot and release strong-smelling gases: geosmines, mercaptans, dimethyl disulfides. A good specialist can even judge the chemical composition of water by this aroma. If it appears, you must stop using the source and find out the cause of the problem.

Substances that change aroma are called odorants. All of them are divided into two groups: natural origin and artificial. The first includes putrid, swampy, earthy odors. The other is those that are released after agricultural inputs (fertilizers) or industrial wastes enter the well.

The table below provides information on what water most often smells like:

SmellCausesDangerElimination method
Rotten eggsPresence of hydrogen sulfide in waterVery harmful to the bodySource purification, use of degassing devices
Swampy (musty, woody, earthy smell)Presence of organic matter in the sourceWeak, liquid is unpleasant to drinkWell cleaning, use of carbon filters

Chemical compounds (iodine, phenol)Proximity of wastewater to chemical plantsVery dangerousIt is necessary to dig a new well in a different place, disinfection, reverse osmosis filters
GlandHigh concentration of iron salts in aquifer Very strongUse of cleaning systems

If it comes from the well water that smells like rotten eggs, there is no doubt about the presence of hydrogen sulfide in the mine. It is formed during the decomposition of protein under the influence of anaerobic bacteria. Conditions for the development of microorganisms (sulfur bacteria) arise in long-uncleaned wells, clogged on all sides with clay layers. They feed on sulfides and sulfates and are able to develop without oxygen. Most often, hydrogen sulfide is formed in deep wells, including artesian ones, where there is no fluid circulation.

Hydrogen sulfide is a very poisonous volatile asphyxiating gas. After inhalation, dizziness appears, the sense of smell is lost, and fatigue is felt. It causes serious poisoning. When the mixture enters the human body, it disrupts vital processes, for example, iron oxidation. A person may find himself in a state of collapse. A gas concentration of 700 mg/m3 is lethal to humans.

Liquid containing hydrogen sulfide can damage plumbing fixtures, shut-off valves, cause corrosion of metal parts. Therefore, if gas is detected in the well, replace all pipes with plastic ones.

Swamp smell well water appears if microscopic plants and microbes are present in the mine. Sulfur pyrite, which is found in large quantities near peat deposits, also produces a foul gas. This aroma is often felt in the spring, when algae and bacteria begin to grow rapidly in the spring.

Putrid smell does not always indicate well contamination. If only hot water from the tap smells, the reason for this is contamination of the heating elements. heating device, on which a thick salt layer is formed. There are always bacteria in them.

Much less common is water from a well. smells like iodine. Its aroma is felt after chemical plant wastewater containing phenol enters a well. As a result, a very toxic substance is formed, poisoning all sources in the area. If an unpleasant odor is detected in water in a well, it is necessary to submit samples of the liquid for analysis to determine all the harmful components dissolved in it. Drinking water with the aroma of phenol is strictly prohibited.

Dirt enters the well different ways. The stench is felt after the source is polluted by flood waters containing organic matter, which decomposes and releases gases. You can protect the source using a caisson. It is a box of different material, dug into the ground to a depth of about 2 m. A small underground room will prevent various debris and dirty water from entering the well.

Due to the violation of the integrity of the shaft, the formation of cracks and gaps in the joints of the elbows, dirty water can seep into the well. It is necessary to repair the damage, even if this means spending significant amounts of money. If sulfide bacteria enter the source, it will smell like hydrogen sulfide.

In the absence of liquid circulation in the water intake part of the well, the percentage of oxygen in the water, which destroys sulfur bacteria, decreases. For the same reason, a large amount of silt appears in the well if the source has not been used for a long time or water has been downloaded very rarely. To saturate the liquid with oxygen, use an aerator.

Well contamination with chemicals most often occurs in areas that are too close to fuel and lubricant warehouses or industrial enterprises.

If the mine is drilled into sulfide ore deposits, there is a good chance that the water will smell like rotten eggs.

Methods for eliminating water odor

To decide how to get rid of the smell of water in a well, determine the reasons for the appearance of the odor. If a large amount of rotting organic matter is found in the mine, it must be washed. In this way, silt and organic debris are removed from it, along with microorganisms that entered the mine from the surface. Fetid fumes associated with chemical composition soil in the aquifer cannot be eliminated by cleaning the trunk. To solve the problem, you will need special filters that are installed on the surface. Let's take a closer look at what to do if the water from the well has an odor.

Eliminating the swampy smell of water


It is possible to rid water from shallow wells of the unpleasant smell of rotting by flushing the shaft with a pump pump, which removes organic matter and other decaying elements.

The work is performed in the following sequence:

  • Prepare a large container and place it next to the mine. Fill it with water. The volume should be enough to fill the casing to the top. If there is a source of water nearby, for example a river or pond, the tank does not need to be installed. In this case, find a place where the dirty slurry will drain, otherwise it will turn the entire area into a swamp.
  • Install a powerful water pump next to the well. Place the suction hose in the prepared container. Lower the outlet to the bottom of the well.
  • Place a special nozzle on the head of the column, which will allow water to be drained into the tank.
  • Turn on the pump. The flow of water from the water pump will lift dirt from the bottom and remove it from the shaft into the prepared container. Heavy particles will settle to the bottom, and the pump will pump the purified liquid back.
  • Periodically remove debris that has accumulated at the bottom of the tank.
  • After flushing, install a pump in the well and pump out all the cloudy liquid. Along with it, all sources of stench will be removed.
Even if dirt remains in the source after cleaning, the oxygen in the water supplied from the surface will destroy microorganisms.

To rid water of the smell of rot in a very deep mine, two pumps are used - a surface pump and a centrifugal device. Place a large tank next to the source and fill it with water. Drop it into the well centrifugal pump. You can use the product in a well. Pull the hose from it to the tank.

Place a water pump nearby, which will take liquid from the prepared container and supply it to the barrel. Install the pump discharge hose into the casing pipe and pull it past the centrifugal pump to the bottom of the source. Turn on both products.

A powerful stream will wash away the bottom sediments, and a centrifugal pump will pump them to the surface and direct the dirty water through a hose into the sump. In it, heavy particles will settle to the bottom, and the liquid will be directed back into the well. After rinsing, pump out all muddy water from the mine.

Removing hydrogen sulfide odor from water


This option is used if the smell of hydrogen sulfide in the water from the well has not disappeared after removing all unpleasant-smelling elements from the mine. You can get rid of it in three ways - physical, chemical and sorption-catalytic.

Physical way based on the property of this substance to evaporate quickly. It involves installing special devices at the outlet of water from the hose, before pumping it into the water supply system. There are two types of such products - non-pressure and pressure.

Non-pressure are plastic tanks, which are filled through sprayers (nozzles) with water from the well. Oxygen from the air oxidizes most of the hydrogen sulfide, and the remaining residues disappear. The device is usually installed under the roof of the house, from where water flows into the system by gravity.

Pressure systems differ in the size of the tank and the method of supplying water to the containers. The liquid enters the column from below under pressure. In the tank it is saturated with oxygen, which destroys the source of the odor - bacteria. After the procedure, the liquid can be used for cooking.

Sorption-catalytic method eliminating stench uses the properties of certain materials to promote the oxidation of hydrogen sulfide. The best catalyst is considered to be ordinary activated carbon. To remove the smell of water from a well, pass the liquid through a filter with this filler.

Chemical method It is used due to the properties of ozone, hydrogen, and sodium hypochlorite to oxidize hydrogen sulfide. You can also find out the composition of the liquid and use oxygen for oxidation, which reacts with the elements present in the source to form insoluble precipitates.

The cheapest substance is potassium permanganate, which reacts with hydrogen sulfide to form colloidal sulfur, which precipitates. The addition of manganese compounds also leads to the appearance of solid salts. Similar properties of potassium permanganate are used in double regeneration filters. Resulting from chemical reaction Manganese hydroxide has the ability to absorb hydrogen sulfide. Any solid sediment that appears must be removed periodically.

Most effective chemically To rid the water of this substance, add hydrogen peroxide. As a result of the reaction, insoluble sulfur is formed, which is removed using a carbon filter.

Removing iron and chemical odors


To remove the smell of iron, iodine, phenol and other chemical elements, it is recommended to use special filters various types. Which devices need to be used are determined only after a chemical analysis of the water. Often they are part of a comprehensive fluid purification system from a well, which also makes it possible to remove dissolved gases, impurities and microorganisms from it, which can cause stench.

To prevent water from being repelled by an unpleasant chemical aroma, use the following devices:

  • To get rid of the characteristic iron smell of water from a well, use reagent or non-reagent type iron removal filters. Some models use oxygen to convert ferrous iron into ferric iron, while others contain manganese sand, which removes ferrous compounds very quickly.
  • It is necessary to include a water softener in the water supply system, which is used if very hard water is planned to be heated by boilers. Without this device, salt deposits will appear on the heating elements, in which microorganisms multiply. The waste products of these bacteria smell very unpleasant.
  • Often the liquid is passed through reverse osmosis - a membrane with a huge number of small holes. It is fed into such a filter in large quantities under pressure, as a result, all impurities remain outside the membrane. Water comes out of reverse osmosis High Quality, without any smell.
