How to get rid of the smell of water from a well

Only clean water should be used for drinking and household needs. With a centralized water supply system, these tasks are dealt with by specialists. If a specific smell of water from the well appears, giving off a swamp or hydrogen sulfide, the master must personally take action. Otherwise, such a liquid with a cloudy bloom on top and amber is unusable.

Causes of an unpleasant odor

The main reason for the appearance of a swamp stench from water is the decomposition of organic substances in it, their rotting. The above substances get there in this way:

• Together with sand particles seeping into the casing. When the bottom of the source is silted, the growth of organic matter in the water increases.
• Through the unprotected top of the well / well. Small debris, insects, small specimens of the fauna (bat, bird) may well get into the column.
• Low intensity of operation of the source. Stagnant water in it leads to the formation of a layer of silt from the bottom. This can give off a swamp stench.

In all three cases, processes occur in the lower layers of the well, during which anaerobic (living without oxygen) bacteria actively develop. They also provoke the appearance of a swamp smell.

Such a liquid foams strongly when boiled.

Is it possible to drink water with a smell

At the very least, the sharp, repulsive aroma simply does not allow a person to consume such liquid for food. But even if you boil it and thereby eliminate the rotten smell, the water is not drinkable. A liquid enriched with hydrogen sulfide threatens with the following consequences:

• indigestion and, as a consequence, diarrhea, vomiting;
• serious food poisoning;
• headaches;
• convulsions;
• nervous paralysis;
• pulmonary edema.

The presence of hydrogen sulfide in water greatly complicates the process of iron removal. Therefore, if the master has special filters for the well fluid, they will not cope with bivalent Fe in the presence of a third-party gas. At the same time, they will fail very quickly.

Ways to solve the problem

When the water from the well smells like sewage, a number of actions should be taken to eliminate the amber. For this purpose, first of all, the cause is identified. Then the source is thoroughly pumped using a powerful water pump. Desirable drainage, since there is a possibility of pumping out a thick sand mixture from the bottom of a home source. Change the bottom filter if necessary.

If the reason for the ingress of organic matter into the casing is pipe depressurization, it makes sense to mount a narrower polymer barrel into it. Often the masters correct the situation in this way.

Further, to eliminate the pungent odor, they act depending on the available means and capabilities.

Physical methods of water purification

Aeration is the saturation of the fluid from the well with oxygen. If anaerobic microorganisms actively live and multiply without it, the enrichment of water with the desired gas will lead to the neutralization of active processes. The smell of hydrogen sulfide will go away.

There are two types of aeration plants:

• Pressure. Oxygen is supplied to the column under pressure. The so-called water enrichment takes place. As a result, hydrogen sulfide is displaced and volatilized.Gas is removed by this method often at industrial sewage treatment plants or in home flasks-aerators.
• Free-flow. The liquid is poured into the storage tank, like from a standard watering can in a bathroom. When water is enriched with oxygen, hydrogen sulfide is separated from its molecules and escapes into the atmosphere. After the aeration process, bivalent iron precipitates in parallel, acquiring the trivalent form. The oxygenated water can be fed into the water pipes.

The main advantages of aeration are that no hazardous chemicals are used to purify the liquid, and the method itself costs almost nothing to the owner of the source.

Chemical odor elimination

If the water in the well smells like a swamp, you can use special reagent chemicals. When they come into contact with sulfur molecules, the latter lose their activity. The following are used as aggressive substances:

• hydrogen peroxide;
• chlorine - its interaction with hydrogen sulfide molecules leads to the formation of colloidal sulfur, which is later removed by coagulation;
• ozone - leads to the formation of an insoluble sediment and further improves the taste of the liquid;
• sodium hypochlorite;
• iron hydroxide - leads to the formation of suspended particles in the water, which settle to the bottom and are then removed by mechanical filtration.

All chemical odor removal methods are difficult to use in the home. The difficulty lies in the selection of the correct dosage of reagents for a given volume of liquid.

Sorption catalytic method

Good catalysts for getting rid of the stench are black activated charcoal or granular charcoal. Water is driven through them, which leads to the oxidation of sulfur compounds. The effectiveness of the method is high. But the main disadvantage of such cleaning is the long process duration. This is not very convenient for large volumes of water used for domestic purposes.

Special filters with coal loads help to get rid of the smell of water from the well. They eliminate rotten amber quickly.

Complex cleaning methods

Even if the fluid from the well is visually clean, but it is clearly perceptible that it stinks, a qualitative analysis should be carried out first. Then select a complete cleaning unit. Even in a transparent environment, bacteria, impurities of hydrogen sulfide, iron, nitrates can be present. Already according to the actual composition of the water, it is worth choosing and making a complex installation. As a rule, it consists of the following sections:

• an ultraviolet emitter that kills all microorganisms, bacteria;
• reverse osmosis installation, with the help of which the liquid gets rid of suspended matter, dissolved impurities;
• flask with carbon backfill for high-quality post-treatment.

The sequential passage of water through all sections ensures the complete removal of all visible and invisible impurities, gases, microorganisms from it. At the exit, a liquid is obtained that is suitable for domestic use.

The main condition for the full-fledged operation of new complex installations is the regular replacement of membranes, carbon plugs, and cartridges.

If you have encountered difficulties with the choice of a complex filtering unit even after conducting a water analysis, it is better to trust the specialists. The masters working with the treatment plants will select the complex in accordance with the laboratory parameters of the liquid. In addition, large companies engaged in the installation of filters give a guarantee for all types of equipment and provide service for their equipment.
