Membrane bioreactor technology for wastewater treatment

摘要

MEMBRANE Bioreactors or better known as MBR is a technology based on the use of membrane systems combined with biological processes to get superior clear water discharge and it is commonly used in industrial and household wastewater treatment. In the past, membrane applications have generally been put aside as secondary option due to its high service maintenance cost but recent development on producing better and cheaper membranes coupled with more stringent regulatory controls to have higher effluent quality have aroused wide interest to make it as an important treatment option. It is also looked upon as a potential solution to the conventional wastewater processes involving use of clarifier and sedimentation and overall, unlike the old systems, MBR offers better discharge quality, smaller footprint and yet capable of handling high COD loading rate.
