Application of a Hybrid Membrane Bioreactor (H-MBR) Process to Treat Dye Wastewater
An enhanced membrane bioreactor (eMBR) consisting of two anoxic bioreactors (ARs) followed by an aerated membrane bioreactor (AMBR), UV-unit and a granular activated carbon (GAC) filter was employed to treat 50-100 mg/L of remazol blue BR dye.The COD of the feed was 2334 mg/L and COD:TN:TP in the feed was 119:1.87:1.A feed flow rate of 5 L/d was maintained when the dye concentration was 50 mg/L;10 L/d of return activated sludge was recirculated to each AR from the AMBR.Once the biological system is acclimatised, 95% of dye, 99% of COD, 97% of nitrogen and 73% of phosphorus were removed at a retention time of 74.4 hours.When the effluent from the AMBR was drawn at a flux rate of 6.5 L/rn2.h, the trans-membrane pressure reached 40 kPa in every 10 days.AMBR effluent was passed through the UV-unit and GAC filter to remove the dye completely.
