Introduction Recently the fast increase in the cost of energy and the decrease in the used economic fossil fuel reserves cause an increase in the interest to the energy production from wastes using anaerobic biotechnology Speece 1996 . The anaerobic treatment is defined as the biological separation of organic wastes in anaerobic conditions and also the production of their last products such as CH CO2 NH and H2S biogas . The processes employed by anaerobic bacteria have been widely used in treatment of municipal wastewaters and varying types of industrial wastewaters for removal of organic material in the wastewaters and also produce biogas as energy from the wastewaters. Treatment capacity of an anaerobic digestion system is primarily determined by the amount of active microorganism population retained within the system dependent on wastewater composition system configuration and operation of anaerobic reactor Zainol et al. 2009 . 2. Important Textiles and apparel sector one of the important industries in the world is a vital contributor to Turkey s economy accounting for approximately 10 percent of the country s gross domestic product. It is the largest industry in the country constituting approximately 15 percent of manufacturing and about one-third of manufactured exports. Nowadays the country produces the eighth-largest volume of man-made fibers in the world at million tons per year Pelot . . Therefore textile industries are vitally distributed in the country. The variety of raw materials chemicals processes and also technological variations applied to the processes cause complex and dynamic structure of environmental .
