Purification of water for water supply system a country house

As a general rule, the water enters the house or from village water supply, either from the well. If the water supply system provides an acceptable quality of water (be sure to make the analysis of water entering the water system of your cabin), the principles of water treatment are similar to those for water rent. unprepared water (water from well) requires a more thorough cleaning. If follow the path of water from the source, it turns out that her fall groundwater, precipitation, passed through a layer of soil. On the one hand, the soil - a good mechanical filter and retains the insoluble particles. And on the other, the water percolate through the soil dissolves many harmful health materials - fertilizer, heavy metals, pesticides, etc. The result is that the spring water near the industrial cities of not so clean. It can be used without deep cleaning water only tested artesian springs, as in the soil above the artesian layer is a waterproof layer. He does not mix with groundwater artesian. The composition of water in these wells is almost unchanged with time. But even the water from artesian wells requires the removal of dissolved salts, hardness and iron, which is typical for the suburbs. Because large volume of water consumed water purification filters for houses need high-performance and easy integration of household filters with replaceable cartridges, used to purify water from the municipal water supply, would make water too expensive. Today, the main trend of water treatment systems for autonomous water supply - the use of water purification and replacement renewable reagents. You can call these filters are intermediaries between domestic and industrial. Stages of Water Treatment All incoming water must first pass the mechanical treatment. Moreover, unlike most types of household filter systems mechanical cleaning water filters, semi-completed drainage system. In the unprepared water content of insoluble particles may be significant and ordinary household mechanical filter (prefilter water) will have to change too often. Restoring the mechanical filter water in the system of independent water supply cottage by periodic pumping through it in the opposite direction of clean water. Water from the washed particles while leaving a drain. rough water purification a water treatment system for the cottage usually produce aluminum silicate, and particles smaller than 20 microns delayed a special ceramic powder. The next stage of water treatment system for the cottage removes dissolved salts of iron and manganese (iron removal of water). As a filter media for iron removal of the substances are used, including in its of manganese dioxide. It serves as a catalyst for the oxidation reaction, and dissolved iron and manganese precipitate, which is delayed in the fiber filter media, and Backwash washed into the drainage. In the process of oxidation of iron and manganese are some filters water treatment system removes dissolved in water hydrogen sulfide. The next stage of water - reducing water hardness. The water passes through an ion exchange water softener filter, which in passing with hardness salts also removes ions of some heavy metals. Regeneration of the filter is a special solution. The last stage of the chemical treatment of water from wells - adsorptive carbon filter. His task similar to those mentioned above, household filters for water purification of urban water supply, but unlike them, adsorption filters water treatment system for the cottages are regenerated. Regeneration occurs through the reverse flow of water. One of the important stages of water treatment - disinfection of water. It unprepared water can contain a huge number of pathogenic bacteria. Chemical technology used for this purpose in household filters are too expensive. The standard solution - water disinfection with ultraviolet light. Water is pumped through a transparent cell, illuminated UV lamp. validity of such a filter is practically unlimited, and this technology has been widely applied not only in cottage, but also in industrial water treatment. If you think this is the end water treatment, it is not so. The process outlined above water is all water used in the cottage, and drinking water after all that has yet to undergo further post-treatment normal household filter , like those installed in flats. Here the process can be somewhat simplified, because the water has no iron salts, hardness, bacteria. doochistit left her a little, and you can drink the water of the highest quality!
