Claims12
Waste water treatment apparatus comprising, in combination:
- a closed ozone absorption chamber having an electrically grounded conductive inner wall surface at least one spray nozzle having a nozzle outlet communicating with the interior of said closed ozone absorption chamber;
- a waste water inlet communicating with said spray nozzle;
- means for supplying waste water under predetermined pressure to said waste water inlet for discharge of said waste water into the interior of said ozone absorption chamber in the form of a non-atomised spray from said spray nozzle outlet to impact on said chamber inner surface;
- means for electrically charging said waste water prior to the discharge of said waste water from said spray nozzle outlet to provide transfer of an electrical charge from the waste water to the chamber wall at said impact, an ozone inlet communicating with the interior of said ozone absorption chamber;
- means for supplying ozone under pressure to said ozone inlet for intimate mixing of said ozone with the sprayed waste water;
- and a waste water outlet for withdrawal of ozonated waste water from said ozone absorption chamber.
