Abstract: Industrial processes create a variety of wastewater pollutants which are difficult and costly to treat. Wastewater characteristics and levels of pollutants vary significantly from industry to industry. The growth of industrialization leads to the rise of wastewater from various industries and so the pollution load on the environment is increasing. The high cost for the treatment and disposal of industrial wastewater is now become a challenging problem for developing countries. The sample used in this research was combine wastewater from distilleries, sugar factories, candy factories and textile dyeing factories. Among them, distilleries and textile dyeing factories are the most wastewater producing industries and the wastewater from these are not easily biodegradable. Total chemical oxygen demand COD of wastewater sample was too high about 30000 mg/l and biochemical oxygen demand (BOD5) also high over 7000 mg/l. Conventional wastewater treatment is not sufficient to treat this amount of pollution and chemical processes are now widely adapted.
