Abstract :Today a number of such industries as textile, paper and printing whose processes involve dyes discharge wastewater containing heavy pollution load directly into a receiving environment. Dyes, which are mutagenic and carcinogenic, spread across the receiving environment, threatening aquatic populations and human health severely. It is possible to reduce the contamination caused by these dyes by using biological methods. In this study, the biosorption technique is utilized for the treatment of textile industry wastewater. In order to achieve optimum efficiency, the optimal pH insert ignore into journalissuearticles values(4-5-6);, temperature insert ignore into journalissuearticles values(30-40-50 °C);, biomass insert ignore into journalissuearticles values(0.025-0.05-0.1 g.); and stirring speed insert ignore into journalissuearticles values(75-100-125 rpm); were determined with the help of Taguchi L 9 orthogonal array design. During the biosorption process, the sorption capacity of live cell Aspergillus terreus with remazol red dye measured 16,4 insert ignore into journalissuearticles values(mg/g); and the removal efficiency measured % 75.3 in conditions of pH 4.0, temperature 30 °C, biomass 0.1 g. and the rotational speed 125 rpm.
