AN IMPROVED EFFLUENT TREATMENT PLANT USEFUL FOR THE TREATMENT OF TANNERY WASTEWATER TO OBTAIN NON-POLLUTING WATER AND A PROCESS THEREOF

摘要

The present invention reports an improved effluent treatment plant useful for the treatment of tannery wastewater to obtain non-polluting water, which comprises an improved conventional effluent treatment plant (CETP), characterized in that the said CETP being provided in combination with an electrochemical reactor selectively at stages the receiving sump stage, post anaerobic lagoon treatment stage, post secondary clarification stage and pre final discharge stage and the said electrochemical reactor consisting of anode which is a plate of conductive metals having electrocatalytic coating such as metallic or ceramic and cathode of stainless steel of similar geometry as that of the anode and the distance of anode and cathode being kept in the range of 2- 4 cm and current density of the electrochemical reactor being kept in the range of 2-4A./dm2.
