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 signifıcant 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 ıo aquatic organisms. Especially, treaıment of textile wastewater is diffıcult because the dyes include organic nıolecules and are durable to light, heat and oxidizing agents. There is a serious need for a prucess that will be efficient and low-cost application for the removal .of contanıinants from waste water. Biological treatment ınethods have attracted much attention due to the relatively simple and ecologically friendly treatnıent processes as well as their relatively low fıxed capital investment and operating costs. Recently. more attention has been paid to the nıenıbrane bioreactor (MBR) for wastewater treatment because of its higher efficiency of pollutant removal and excellent effluent quality. In this research, the decolourization process of Diamozol Blue BRF %150 (C.l. Reactive Blue 221) dye by using activated sludge collected from wastewater treatment facility in Bilecik First Organized Industry Zone was examined in membrane bioreactor.
