Membrane Bioreactor (MBR)

Sewage treatment plants that employ the Membrane Bio-Reactor (MBR) process are the systems of choice where the production of high quality water effluent is an advantage. MBR processes are therefore ideal for re-use applications, whereby the treated effluent is used for irrigation, watering or wash-down uses. MBR Technologies use a bank of membranes that are either immersed in the final effluent tank or are immersed in a separate side-arm tank to filter out biological solids as a final stage in the STP processes. The result is that MBR plants provide a high purity effluent. A Chlorination storage tank is usually incorporated into the process design to ensure that the water produced can be stored safely. The MBR process also operates at high sludge levels, so less sludge volume is required to be treated or transported off-site.
