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.
