Abstract: The wastewater treatment apparatus of present invention has an electro-coagulation unit for removing contaminants with at least one anode and at least one cathode and an electro-oxidation unit for oxidizing contaminants with at least one anode and at least one cathode wherein oxidants are electrochemically generated. Based on the type of wastewater, the apparatus can have an electro-flotation unit between the electrocoagulation unit and the electro-oxidation unit. The apparatus also has an oxidant removal unit which can have a metal ion-liberating electrode for reacting with and removing residual oxidants. In some cases, portions of effluent from the oxidant removal unit can be recirculated to the electro-coagulation unit for increased efficiency.

Abstract: An integrated device for wastewater purification, comprising a coagulation zone; a flocculation zone connected to and in fluid communication with the coagulation zone; a flotation zone connected to and in fluid communication with the flocculation zone and comprising a froth discharge port; and a separation zone below and in fluid communication with the flotation zone and comprising a contaminant separator and a purified wastewater discharge port; the wastewater entering the device being mixed with electrolytically-generated coagulants and gas bubbles in the coagulation zone; the flocculation zone receiving and gently mixes coagulated wastewater contaminants and gas bubbles formed in the coagulation zone and aggregating them into flocs before flotation of buoyant flocs in the flotation zone and the separation zone being adapted for further floc formation, oil coalescence, settling and discharge of non-buoyant contaminants.
