A REVIEW OF THE USE OF MEMBRANE BIOREACTOR TECHNOLOGY IN WASTE WATER RE-USE

摘要

The technology into combining membranes with wastewater biological treatment began over 30 years ago and has been in commercial use for the last 20 years. There has been expanding interest recently into Membrane Bioreactor (MBR) technology for waster water treatment because of the increasing number of water repurification projects and advances in MBR technology. The MBR technology, not only allows a community or country to improve the quality of treated effluent into the environment, but also allows a greater number of options for water re-use when a high quality of effluent is available. The MBR technology offers benefits over the conventional activated sludge process, which includes smaller space and reactor requirements, better solids removal, disinfections and less sludge production. The MBR process is cost competitive with other conventional wastewater treatment processes, but have been most successful in the treatment of concentrated wastes where the biological reactor is large, but the hydraulic capacity (size of the membrane system) is small.
