Textile industry effluents are among the most difficult to treat, due to the considerable amount of recalcitrant and toxic substances. Fungal biosorption is viewed as a valuable additional treatment for removing pollutants from textile industry wastewaters. In the present study, the efficiency of Aspergillus niger for chemical oxygen demand (COD) reduction was tested against textile effluents having three dilutions i.e., 25%, 50%, 75% and raw effluent. The result showed that the fungal strain is a promising candidate for the reduction of COD in effluent and can be a cost effective solution to treat the textile industry effluents.
