Abstract

An electrochemical treatment plant for industrial wastes, esp. effluents with an oil and grease content, consists of a vertical cylinder which forms with an outer vessel an annular space for the sludge collection and discharge. An electrolyte inlet and electrodes are fitted in the bottom of the cylinder. An air ejector, rotated near the top cover, disposes of the produced floating scum. The continuous disposal of the scum prevents the consolidation of foam in the settling space. It improves the cleaning efficiency, raises the capacity and lowers the operational costs.
