ABSTRACT:
An apparatus is provided for cleaning vehicles which utilizes recirculated wash water to clean a vehicle, thereby saving water and expense in operation. The apparatus utilizes a clarifier tank which receives partially clarified water under pressure from a sump pump to produce a swirling flow of water within the tank which separates sediment centrifugally outwardly in the tank where it drops in a swirling path due to gravity and is collected in a conical base portion of the tank for expulsion therefrom. Clarified water is drawn out from the tank from an upper central portion therein. Preferably, a settling pit is used to partially clarify the water before it enters the clarifying tank. Furthermore, a pre-filter such as a cyclone separator is also utilized to pre-filter wash water before it is clarified in the clarifying tank. The drawn off clarified water from the clarifying tank is then pumped to a plurality of washing nozzles which assists in washing a vehicle passing through the apparatus.
