Preparation and characterization of ceramic microfiltration membranes for removal of Cr (VI) and Pb from electroplating effluent

294-302Present work deals the removal of Cr (VI) and Pb from electroplating effluent (EPE) using ceramic membrane MD-1 (ceramic membrane without coating) and MD-2 (ceramic membrane with chitosan coating). Uniaxial compaction followed by sintering process has been applied to prepare the membrane from locally available clay. Results indicate that maximum removal of 65% Cr (VI) and 68% Pb has been achieved by use of MD-1 membrane, while, MD-2 removed 81% Cr (VI) and 93% Pb, from the initial feed concentration of 55.3 mg/dm3 Cr(VI) and 3.5 mg/dm3 Pb at optimum operating condition pH 3.5 and applied pressure 300 kPa
