System for purifying water from artesian wells from natural radionuclides

摘要

The installation is designed to purify water from artesian wells from natural radionuclides. It contains a coarse filter 1, an aeration unit 2, a second lift pump station 3 and an ultraviolet sterilizer 4, a reverse osmosis unit 5 installed in front of the aeration unit, separating the water flow into the filtrate, accumulated in the aeration unit and highly mineralized concentrate discharged into the drainage and a complex 6 for dosing a reagent for feeding a scale inhibitor on the membrane elements, located before the installation of reverse osmosis 5. Under normal conditions, As a source of water, the installation includes an additional line 7 of the mixture of source water, located after the coarse filter 1, on a dedicated separate piping system, bypassing the reverse osmosis unit 5 and including the adjustment mechanism 8 for filling the aeration unit 2. Air is pumped into the aeration unit 2 using a low-pressure compressor 9. The system eliminates the risk of an emergency stop of the system due to the formation of deposits in the tank, pumping equipment and distribution network. The piping system of the installation consists of two parts connected in series through an aeration unit. 1 ill.
