The rules for perfect water treatment

How to choose a filter for washing, depending on the quality of the water

We all have long known that drinking water from a tap or from a well is a risky undertaking. And do not even drink, just using such water for technical needs can be dangerous - it can disable a gas boiler, plumbing, shower.

In suburban life, high-quality water treatment is crucial, but there are no universal solutions: the filter must be selected depending on the composition and quality of the water

 Why water analysis is needed

Residents of the countryside, as a rule, take water for life from a well or well. And if the water from different surface sources is more or less similar, then the water from two different wells is likely to be radically different. Moreover: in the water from the well may contain substances that in principle are absent in surface sources. Therefore, the approach to cleaning it should be more serious, but first you need to find out what kind of water you have to deal with.

The first thing you need to pay attention to is the total salinity. It can be either very low or sky-high. The norm for drinking water is 250-400 mg / l, MPC - 1000 mg / l. In the well, this value can be exceeded at times. Three other parameters that need attention: hardness, iron and manganese content. When designing water treatment from a well, it is also necessary to measure the nitrate content; exceeding the MPC for nitrates is a common problem. There may also be problems with excess fluoride. In our work, we even encountered wells with arsenic, radon, nickel, and other non-specific contaminants.

It is impossible to evaluate the composition of water visually and using the method “draw water into a two-liter plastic bottle, shake and smell” - an analysis must be done before installing the filter.
