Wastewater treatment for car washes with a capacity of 3 m³/h

Wastewater from a car wash, after passing through underground water pre-treatment facilities, including a sand sump and a grease trap, enters the sewage treatment plant via a pressure line, in which oil inclusions and large aggregate pollutants are retained at the first stage., At the second stage, a coagulant is injected into the water and it enters a foaming reactor tank in which, under the influence of aeration equipment and coagulant, small colloidal pollutants clump together into large conglomerates and detergents present in the water are whipped into foam that accumulates on the surface of the water and disposed of by a discharge pipeline. At the next stage, water with large inclusions, under the influence of a pressure pump, enters a column of mechanical purification, in which, during a multi-layer loading, the water is purified from all mechanical pollutants with a rating of more than 30 microns, then the clarified water passes through a BB20 cartridge-type mechanical purification filter with a degree of purification of 5 microns and enters a storage tank from which under the action of the pumping station, the water returns to the recharge tank of the high-pressure pumps of the car wash.
