How to destroy an infection in homestead water?

If you on the personal plot extracted water from a well or a well, it does not mean yet that in it there are no viruses and bacteria. They are, and some of them can directly threaten your health. How to get rid of them?

A classical method of disinfecting of drinking water water processing the substances emitting active chlorine - salts of hlornovatisty acid, chloroamine, etc.

However is considered if water is insufficiently purified of organic compounds, in it a number of organochlorine connections, including the dioxine hazardous to health of the person is formed.

The perspective disinfecting means is ozone. It is received in special ozonizers, in them the dry purified air is subjected to influence of a silent discharge.

Ozone as the disinfecting means, works quicker than chlorine by 15 - 20 times. At the same time the consumption of ozone is less, and the range of action is more, than at chlorine.

Ozone gets in a bacterial cage and oxidizes substances which are a part of cytoplasm.

Not so long ago rather small household ozonizers were available for sale. Their productivity quite is enough to provide a family with the disinfected drinking water.

Efficiency of ozonization is influenced by neither temperature, nor a turbidity, nor chromaticity, nor rn waters. It does not bring in water of additional pollution.

However it is korrozionno active therefore, applying it, it is necessary to use especially resistant materials. Besides, pure ozone is explosive. Its mixes with air are explosive to a lesser extent. Nevertheless, work with ozone demands certain security measures.

The method of disinfecting of small amounts of water silver is popular. Ions of silver destroy cytoplasm of a bacterial cage, interact with its enzymes, block them and break a metabolism between a cage and environment. Disinfecting in this case that is more effective, than temperature of the conditioned water and concentration of ions of silver in solution is higher.

The main advantage of this method is that it has the prolonged action - the water conditioned by such method long enough is not subject to secondary infection with microorganisms.

It is possible to enrich water with silver ions just having brought it into contact with metal silver.

In this case silver ions in solution will be that more, than the surface of contact of water with metal therefore silver is napylyat a thin layer on objects with the developed surface is more and filter through them the conditioned water.

Processing by silver is applied to disinfecting of small amounts of water on autonomous objects. Especially effectively to use it in need of long storage of water.

It is possible to saturate water with silver by an electrolytic method much stronger. Under the influence of a direct current the silver anode is dissolved in water much more intensively.

The method allows to establish an exact dosage of ions of silver, and, thus, to regulate disinfecting process.

The water sated with silver ions is called silver water. It on the bactericidal properties is much stronger than such reagents as chlorine and chloric lime

However ions of silver influence microflora of a human body that leads to diseases zheludochno - an intestinal path. Therefore the water sated with silver ions is not recommended to be used in drinking water supply.

And still the harmful microflora can be neutralized, irradiating it with ultraviolet rays.

The mechanism of bactericidal action of ultraviolet rays consists in their influence on enzymes and protoplasm of a bacterial cage. At the same time die off vegetative forms of bacteria, and also disputes, viruses, the elementary perish.

Structurally the devices giving ultra-violet radiation divide into two look:

1. With a submersible source of radiation. In this case the high efficiency of a lamp takes place. These devices have a difficult design.

2. With not submersible source of radiation.

However disinfecting by ultraviolet rays has no the prolonged action and perhaps secondary bacterial pollution of water at its giving on a network.

In case of tertiary treatment of tap water of need for use of expensive UF - there are no lamps.]
