ABSTRACT:
A constant-recirculation filter system for decontaminating and reusing wash water in vehicle washing installations and other applications in which water recycling is needed. The elements of the system are selected to avoid need for backwashing operations, thereby enabling use by unskilled personnel. Unrecycled fresh water is used to rinse vehicles, and to provide makeup water to the recirculating system.
