The work is to water treatment and can be used for high-quality drinking water. The closest to the claimed solution is the installation of storm sewage treatment, including receiving tank-sump unit with separation of suspended solids and oil purification chamber, forcing the filter adsorber filled, located above the maximum water level, made a tank inlet and outlet manifolds, combs Based on the lower capacity, paired with vertical perforated filter elements, the volume between them is filled with a filler with a high specific surface area. The filler used sorbent based on natural opal and kristabolita, at what is a fiber loading based on foamed polystyrene and sorbent with locking top layer of gravel on the perforated plate. Water supply to the filter-adsorber is switched on (off) forces to achieve a given level in the suction tank, sump pump capacity is chosen equal to the peak load. The disadvantage of this solution is the complexity of the steps of the purification of water - for a large number of stages themselves. An apparatus for purifying drinking water from natural sources. Water for cleaning goes through a series of stages: upholding sludge; clarification in sand filter, adsorption treatment that uses sorbent obtained on the basis of flasks Astrakhan region, active carbon and manganese dioxide and has the following composition: silica (SiO2) – 78,5 %; aluminum oxide (Al2O3) – 10,5 %; activated carbon BAU-4 – 5,0 % manganese dioxide (MnO2) – 2,0 %; water – 4 %, the removal of hardness occurs on cation exchanger (cation exchanger KU-2-8), the removal of the anions of strong acids occurs on anion exchanger (anion AU-2), the removal of free carbon dioxide by degassing. The advantage of this setup is simplicity of its construction, ease of operation. Used plant produces water that meets water quality household drinking assignment. Minor changes to the load capacity of the sorbent, cation, anion allow more fresh water, such as fishery.
