Abstract

Meat processing plants as major food processing units consume a large amount of water. In this article, an experimental study of wastewater treatment collected from different meat processing plants in Egypt is demonstrated. Treatment of wastewater was investigated to remove the organic matters and pollutants to reuse the water in different applications like irrigation. Coagulation was used for the treating of wastewater from the meat processing plant. The results showed that coagulation is an efficient process for reducing pollutant in wastewater to the required permissible limits. Different coagulants and concentrations were used in the study. Optimum conditions for the coagulation process are flash mixing at 230 rpm for 1 min, flocculation for 15 min at 15 rpm, and a settling time of 1 hour. Maximum removal of organic pollutants was achieved using ferrous sulphate as coagulant and lime for pH adjustment with a dose of 300 and 400 mg/l respectively. COD and BOD removal efficiency was 92 and 95% respectively. A detailed process for treatment of wastewater from meat processing plants was proposed. An engineering design of wastewater treatment unit is developed based on laboratory and bench scale study.
