Experiments were conducted on treatment of leather effluent by ozonation covering wide range in operating conditions. The influence of parameters such as influent pH, ozone flow rate and initial effluent concentration on ozonation efficiency has been critically examined. A maximum of COD removal efficiency of 92% has been achieved under optimum operating conditions. The ozonation of leather effluent has been modeled using pseudo first order kinetics. It has been observed from the present investigation that the biodegradability index of the tannery effluent has increased from an initial value of 0.18 to 0.49 due to ozonation indicating favorable adaptation of the technique as primer for biochemical methods.
