Method of applying ozone and sonic energy to sterilize and oxidize waste water
First Claim
1. A method of treating waste water having entrained solids and dissolved contaminants therein, comprising the steps of:
- adding a coagulating agent to said waste water;
adding a polyelectrolyte to said waste water to form a floc;
then passing said waste water through a lamina to remove a substantial portion of any solids suspended therein;
passing said waste water in a counter-flow through a large gravity gradient stand of water; and
subjecting said waste water to the pre-treatment of ozone and sonic energy to cause cavitation therein, said waste water being subject to said cavitation at increasing energy levels while it encounters increasing concentrations of said ozone;
forcing said waste water through a restriction into a hydraulic gradient of water and subjecting said waste water to highly confined and increasingly concentrated quantities of ozone in the presence of high ultransonic energy at increasing energy levels to effect cavitation within said waste water for effective sterilization and oxidation of said waste water.

Abstract
A tertiary waste water treatment system wherein the waste water is subjected to physical chemical processes. The waste water is treated with a coagulating agent, a polyelectrolyte and then is clarified in a lamina preferably of unique design. The clarified waste water is then filtered and passed through an ozonation-sonication chamber wherein the liquid flows counter to the ozone. Within the tower, the liquid is subjected to substantial levels of sonication, enough to cause cavitation, either simultaneously with or prior to encountering large concentrations of ozone. After the ozonation-sonication treatment, the effluent may be discharged or it may be passed through an ozone contact chamber.
