Treatment of tannery wastewater produced from an ingeniously leather industry was carried out using a ceramic membrane coated with graphene oxide. The effluent was highly contaminated and thus posed a great threat to the terrestrial and aquatic life by polluting the environment. The current study proposed treatment of aforementioned wastewater with graphene oxide coated ceramic membrane. Graphene Oxide, synthesized by Modified Hummer’s method, was coated on the inner surface of tubular ceramic membrane with a suspension of 5 mg/ml using dip-coating technique. Experiments were performed at different transmembrane pressures ranging from 0.7 bar to 3 bar while keeping the temperature and crossflow velocity constant. Rejection values for total solids, total dissolved solids, total suspended solids, salinity and conductivity were determined to evaluate the efficiency of the coated membrane.
