WASTE WATER TREATMENT AND RECYCLING WATER SUPPLY UNIT Russian patent published in 2025 - IPC C02F1/52 C02F3/00 C02F9/00 B60S3/04 

FIELD: water treatment.

SUBSTANCE: invention relates to water treatment plants for washing vehicles with recycling water supply system at parking lots, filling stations, repair companies and other car service enterprises, which preserve quality of water for washing cars and provide recycling water supply and autonomy of the device. Plant comprises process equipment connected by a system of pipelines with waste water treatment devices, including a collecting tank, a pump for supplying water from the tank to a chemical reactor, coagulant working solution dosing pump, pump for water supply to coarse filter, accumulation tank for collection of purified water after coarse filter. Plant additionally contains a bioreactor. Bioreactor is made in the form of a plastic three-section vessel equipped with level sensors, a foam remover and a biological mass carrier. Between the chemical reactor and the bioreactor there is a pump and a mechanical treatment filter. Pump and a coarse filter are installed between the bioreactor and the storage tank. At least one accumulation tank for collection of purified water contains an ultraviolet disinfectant and an aerator, a float switch. Coagulant dosing pump is made with possibility of flocculant dosing.

EFFECT: expansion of technological capabilities, ensuring improved cleaning quality, eliminating the need for periodic water top-up, reducing the need for frequent sludge removal, ensuring mobility, improving the environmental friendliness of operation, increasing autonomy and service life between repairs.
