Reuse of textile wastewater treated by moving bed biofilm reactor coupled with membrane bioreactor

A laboratory-scale pilot plant of moving bed biofilm reactor coupled with membrane bioreactor (MBBR-MBR) was studied regard to wastewater treatment in the textile industry, and reuse feasibility treated water investigated. The comprised two connected parts: an aerobic tank filled carriers a submerged tank. MBBR-MBR system reduced hydraulic retention time 1 day, which is very promising compared conventional biological industry. removal efficiency chemical oxygen demand reached 93%, almost maximum for process treating this type wastewater, as well colour performance, achieved 85%. Additionally, 99% total suspended solids were removed due filtration. Furthermore, new dyeing processes reusing performed. quality dyed fabrics reference fabrics. Colour differences between found be within general requirement industry (ΔECMC(2:1) < 1). beneficial both environment, because sector intensive consumer during finishing processes.
