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.
