Water treatment plant for vehicle wash bays

摘要

Method and apparatus are claimed for treating and recycling water at a vehicle wash bay. The used water drains from the wash bay to an underground settling tank and passes through an oil separator into a collector tank, from which it is circulated through an injector where ozone is introduced to break down pollutants, and returned to the settling tank. In a separate circuit water is pumped from the collector tank pumps through a microfilter; the filtrate is fed to a storage tank for further use.
