Station, useful for treating waste water from washing of vehicles, comprises deoiler arranged downstream from centrifugal machine, and UV generator arranged downstream from deoiler to neutralize proliferation of organisms in de-oiled water
The station comprises a surge tank (3) for storing waste water to be treated, a centrifugal machine (4) arranged downstream from the surge tank for separation of solid particles from the waste water to obtain the solid particles and the clarified water, a deoiler (5) arranged downstream from the centrifugal machine for separating oils from the clarified water to obtain the oils and the de-oiled water, and a type C UV generator (6) arranged downstream from the deoiler to neutralize organisms in the de-oiled water. The generator includes a UV gun comprising a central channel. The station comprises a surge tank (3) for storing waste water to be treated, a centrifugal machine (4) arranged downstream from the surge tank for separation of solid particles from the waste water to obtain the solid particles and the clarified water, a deoiler (5) arranged downstream from the centrifugal machine for separating oils from the clarified water to obtain the oils and the de-oiled water, and a type C UV generator (6) arranged downstream from the deoiler to neutralize organisms in the de-oiled water. The generator includes a UV gun comprising a central channel for a passage of the de-oiled water and two lamps with UV rays extending on both sides of the central channel. The surge tank comprises a cylindrical conical bottom cistern including an exit opening at a lower end of the conical bottom for connecting a waste water routing pipe between a container and the centrifugal machine. The centrifugal machine is a centrifuge scraper. The station comprises: a storage tank (7) that stores the treated water and is arranged in downstream from the generator; and a controller to order an activation of the centrifugal machine, the deoiler and the generator when a volume of water in the storage tank is lower than a threshold. The storage tank includes a volume detector to measure the volume of water in the storage tank. The controller is ready to order opening or closing of a valve connected to an urban water circuit to fill the storage tank. The deoiler includes superimposed wings. Each wing extends between two lateral walls opposite from the deoiler, and is tilted towards a basic wall from the deoiler according to an angle of 40[deg] compared to a horizontal plane parallel with the basic wall. An independent claim is included for a method for treating waste water.
