Removal of Dimozol Blue BRF%150 from Simulated Textile Wastewater in Membrane Bioreactor (MBR) System

Abstract

The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Visually and undesirably, the significant contaminant in wastewater is to be recognized as colour. About 10–15 % of the dyes are lost in the wastewater during the dyeing process. These dyes is also toxic and carcinogenic affect on to aquatic organisms. Especially, treatment of textile wastewater is difficult because the dyes include organic molecules and are durable to light, heat and oxidizing agents. There is a serious need for a process that will be efficient and low-cost application for the removal of contaminants from waste water. Biological treatment methods have attracted much attention due to the relatively simple and ecologically friendly treatment processes as well as their relatively low fixed capital investment and operating costs. Recently, more attention has been paid to the membrane bioreactor (MBR) for wastewater treatment because of its higher efficiency of pollutant removal and excellent effluent quality.
