CAR WASH COMPLEX – OBJECT OF HARMFUL IMPACT ON WATER RESOURCES

Deals with the problem of the impact of car wash complexes in the city of Tashkent on water resources. The analysis of the technological process of washing and a sociological survey of car owners and employees of car washes revealed the average amount of water used per car wash per year, as well as the amount of harmful substances entering the sewer network of the city of Tashkent. Calculations have shown that the annual water consumption only for passenger cars in Tashkent is about 4.34 million m3 , and the wastewater is not properly treated. From one car wash station, on average, up to 743 kg of suspended solids, 446 kg of oil products and 127 kg of synthetic surfactants are annually supplied to the sewage. When these substances enter the city sewage system, they disrupt the process of biological treatment of municipal wastewater.
