Ecological Problems of Operation of Car-Washing Facilities and Means of Their Solving

Summary

A brief analysis of problems connected with the use of water in car-washing systems, disposal and treatment of wastewater generated is made. Main components of the car-washing facility’s wastewater are suspended substances, oil products and synthetic surface active agents. To ensure efficient treatment of wastewater guaranteeing the quality of treated water meeting the requirements of its use in recirculating systems as well as for discharge into sewerage networks, basins or on the relief it is necessary to use a complex of methods including coagulation, flotation, ozonization and sorption. A principal basic flowchart of the use, treatment and disposal of wastewater from car-washing facilities guaranteeing water quality and meeting the normative standards is proposed.

Key words:

coagulation , washing agents , non-ionogenic and anion synthetic surface active agents , oil products , ozonization , wastewater treatment , sorption , flotation
