Abstract

The simultaneous removal of chromium and other organic pollutants from tannery wastewater was investigated in a batch electrochemical membrane reactor This reactor having a total capacity of 1 liter was separated into two compartments anodic and cathodic compartments by using an anionic membrane A stainless steel sheet with the square holes having total surface area of 00215 m2 and a Ti/RuO2 grid was used as the cathode and anode respectively The results indicated that the optimum condition for removal of chromium from tannery wastewater was found at the current density of 605 A/m2 at initial pH of 45 At this condition more than 98 of chromium was removed within 60 min Some organic pollutants contained in wastewater such as oil and grease color and the level of biochemical oxygen demand BOD chemical oxygen demand COD and total kjeldahl nitrogen TKN were also markedly reduced
