Abstract

The present disclosure provides a dissolved ozone floatation effluent treatment system for treating and purifying wastewater comprising: (a) a holding tank for receiving a wastewater to be treated; (b) a contact tank having a water inlet for receiving the wastewater and a treated water outlet for outputting treated water, (c) a first re -circulation fluid line connected to the outlet of the contact tank for carrying wastewater from the contact tank; (d) an ozone injection system connected to the first re -circulation fluid line for dissolving a regulated quantity of ozone in the re-circulated stream of wastewater from the contact tank; (e) a second re-circulation fluid line for conducting the wastewater with dissolved ozone to the contact tank; (f) a container for collecting floating sludge from surface of the treated water in the contact tank; (g) an aerating means in fluid communication with the contact tank for receiving and aerating the ozone treated water; and (h) a discharge line extending from the aerating means for discharging clean water. The present disclosure further provides a method for treating and purifying a wastewater stream.
