Abstract
Waste water is reclaimed for reuse by combined use of settling tanks, ozonation and filtration. The settling tanks remove substantial solid matter from the waste water. The waste water from the last settling tank is treated with ozone to remove contaminants and purify the water. This ozonated water is then returned to the last settling tank to mix with the waste water. This ozonated water in the last tank is then subjected to a plurality of filtering actions before being stored in a clean water holding tank. Partially treated water or discharge from filters is returned to a different holding tank to mix with waste water and dilute the waste water.
Claims11
Apparatus for treating waste water comprising:
- a) a plurality of serially interconnected tanks, each tank having a baffle means;
- b) a first one of said tanks having an inlet for waste water;
- c) a source of ozone purified water, including intake of water and a pump outlet having ozonated water, the intake and outlet of said source connected to a third one of said tanks;
- d) a plurality of filters for removing impurities from ozonated waste water to produce a partially filtered water;
- e) a plurality of pumps for forcing ozonated waste water through said filters;
- f) a tank for holding partially filtered ozonated waste water;
- g) a plurality of control means connected to said pumps;
- h) a tank for holding environmentally approved recycled water;
- i) conduit connecting ozonated waste water in said third tank to a first one of said pumps;
- j) conduit serially connecting said pumps, the filters and the filter output of said filters to each other and to said holding tank for said environmentally approved recycled purified water;
- and
- k) conduit delivering partially filtered water from certain of said filters to a second one of said tanks immediately upstream of said third tank;
- whereby purified water is delivered to said holding tank.
