Process and apparatus for electrocoagulative treatment of industrial waste water
 An electrocoagulation system for removing contaminants from waste effluents comprising an electrocoagulation reactor (140) having charged and uncharged plates and allowing serial flow of water therethrough. The reactor (140) is connected to a voltage source (160) to charge some of the pates positive and negative plates. The system allows waste water to enter the reactor (140) for coagulation therein, the waster water leaving the reactor (140) to enter a defoam tank (200) for agitation which allows trapped bubbles to rise to the surface of the tank (200) as foam. From the defoam tank (200), waste water goes through a sludge thickener, to allow sludge to settle at the bottom thereof and waster water is drawn off from the sludge thickener to flow to a clarifier (250). The pump removes sludge forming at the bottom of clarifier (250) to take it back to the sludge thickener. The sludge is drawn out the bottom of the sludge thickener for transport to a press (280) where most of the water is removed therefrom. Water is drawn off the top of the clarifier (250) for transport to a conventional sewer system, or for reuse.
