Waste water recovery system

Waste water recovery system description/claims

This application is a continuation of U.S. patent application Ser. No. 11/060,112, filed Feb. 17, 2005 by James Keller, currently pending and hereby incorporated by reference in the entirety.

1. Field of the Invention

A waste water recovery system to filter and recirculate waste water from and to a wash system.

2. Description of the Prior Art

Numerous efforts have been made to design an efficient system to recover and recirculate waste water from car washes and other industrial processes. Such designs typically incorporate self-cleaning capabilities to periodically clean filtering devices common to these systems. In order to provide essentially continuous or uninterrupted operation of such wash systems, a secondary supply or source of water is needed during the filter cleaning phase.

Filter devices often include a filter element and an air purge using the fluid in the filter device to dislodge the particulate contaminants adhering to the surface of the filter element and to force the particulate contaminates from the filter device.

However, a need remains to construct a reliable means to provide a virtually uninterrupted flow of recovered water to the car wash or other industrial process.

For a fuller understanding of the nature and object of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which:

FIG. 1 is a schematic diagram of the waste water recovery system of the present invention and a wash system.

FIG. 2 is a top view of the waste water recovery system of the present invention.

FIG. 3 is a detailed cross-sectional view of the waste water recovery system of the present invention.

FIG. 4 is a partial end view of the waste water recovery system of the present invention.

FIG. 5 depicts the position or state of the valve assemblies of the waste water recovery system of the present invention when in the full filter mode or configuration.

FIGS. 6 and 7 depict the position of state of the valve assemblies of the waste water recovery system of the present invention when one of the filters is in the backflush mode or configuration.

FIG. 8 depicts the position of state of the valve assemblies of the waste water recovery system of the present invention when the filter is in the purge mode or configuration.
