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 (4-5-6), temperature (30-40-50 °C), biomass
(0.025-0.05-0.1 g.) and stirring speed (75-100-125 rpm) were determined with
the help of Taguchi L₉ orthogonal array design. During the
biosorption process, the sorption capacity of live cell Aspergillus terreus with
remazol red dye measured 16,4 (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.
