The device operates as follows.

The cleaning solution or water after washing the car contains dirt, oil and fuel. For water treatment, the car wash posts must be equipped with mud traps and oil / gas traps, the principle of which is based on the difference in the specific gravity of water, dirt, oil and fuel. Suspended solids are deposited on the bottom of the tank 13 of the primary sludge, and oil and fuel float to the surface, where they are separated from the water with the help of special equipment or board traps. Oil and fuel can be discharged to the oil pan, which must be cleaned periodically. Water or washing liquid without impurities of oil and fuel flows into the next tank 14, where water is clarified. It should be noted that the process of water clarification is slow, since medium and small particles are in suspension for a long time. The capacity of treatment tanks can be improved by increasing their surface. From the tank 14 - clarification, the water enters the dirt separator 5, where the process of water sludge also continues.

From the dirt-oil separator 5, the water is supplied by a submersible pump 4, first to the sand and gravel filter column 1, where the wastewater is purified from mechanical impurities, and then to the filter column 1 with a sorbent, where the water is purified from oil products. Next, the water through pipeline 3, already suitable for washing cars, enters the storage tank 6. The water level in the tank is automatically controlled.

In the case of a kit with one column 1, water flows directly into the tank 6.
