Technological solutions

In the project documentation in the section "Technological solutions" the main technological solutions in the process of construction and operation of the facility are considered.

 Mechanized car wash

The mechanized car wash is intended for washing cars. The car wash is equipped with a high-capacity washing plant and a conveyor for moving cars made in the USA. 150 cars are serviced at the car wash per day. The car enters the washing post, is installed on the conveyor, the engine is turned off. The car goes through all the stages of washing the car, including washing the body, washing the bottom, wheel rims, washing the tires, drying the car. After washing the car, the car drying starts. Then the engine turns on, and the car leaves the washing post.

Water recycling treatment facilities

Treatment facilities are designed to remove sand, suspended solids from wastewater, reduce the concentration of oil products and disinfect treated water to the regulatory requirements for recycled water used for car washing. The treatment facilities include: mixer; contact chamber of flocculation; flotation tank; foam removal unit; reagent department; air-water mixture preparation unit; lighting and sorption filters; cartridge filters; bactericidal installation; purified water tank; water desalination unit; pumps designed to supply settled and wash water to filters, purified water for preparing an air-water mixture, dosing a reagent solution, pumping sediment and flotation sludge. At the first stage of purification, after mixing water with a reagent solution, water treatment is provided in a flotation-settler with a built-in contact chamber for flocculation. A pipe-type mixer designed for intensive mixing of treated water with a reagent solution is mounted on the source water supply pipeline connecting the tray and the flocculation chamber. The flocculation chamber is equipped with removable filter cassettes 2 with coarse-grained polystyrene foam, which allow intensifying the flocculation processes. The cassettes are periodically washed with purified water as they accumulate in them with purified water, pulling them out one by one. Wash water is discharged into the flocculation chamber. The flotation tank is designed for reagent flotation clarification of water, its settling and extraction of surfactants and oil products. Saturation plant SAV-1600 is provided for preparation of water-air mixture supplied to the flotator-settler. A bactericidal plant designed for disinfection of purified water is a protective casing made of stainless steel, inside which a UV emitter is placed. The plant is equipped with a cavitator and operates in a pressure mode. The purified water tank is designed to store purified and disinfected water for the purpose of its further use in the car wash recycling water supply system.
