Abstract

Large quantities of saline wastewater are discharged. It is found that the efficiency of biological treatment of the saline wastewater by conventional techniques is poor and thereby leads to poor effluent quality, which is mainly due to sodium toxicity to sludge. However, the toxicity can be largely alleviated by compatible solutes or potassium because the chemicals can increase sludge activity effectively. In addition, anaerobic membrane bioreactor can effectively decrease the level of chemical oxygen demand of the wastewater and thereafter provided clean effluent. Hence, anaerobic membrane bioreactor is recommended as a good alternative technique.
