Treatment of Sea Food Industry Wastewater Using Zinc Oxide Nano Catalyst Based Photo Oxidation Process

Abstract

In this present study, Response surface methodology (RSM) coupled with three factor and three level BBD design was employed to optimize the process variables such as catalyst dose, pH, radiation on COD and BOD removal from sea food industry wastewater. A mathematical model and ANOVA was developed to correlate the influencing parameter on the pollutant removal and used to predict the treatment efficiency. Operating conditions was found to be as follows: Catalyst dose of 55 mg/100ml, radiation time of 60min and pHof 4. Under this conditions 91 % of BOD removal and 93% of COD removal was achieved.
