Ultrafiltration membrane separation

Conventional AMBR™ and low energy AMBR LE™ membrane bioreactor processes are the backbone of our industrial effluent treatment and water reuse process. The biological system operatingat high MLSS and tank levels provides a reduced footprint compared with conventional activated sludge or submerged membrane systems, and provides a robust and consistent treatment stage for removing > 99 % COD and BOD. The cross flow ultrafiltration (UF) membranes provide a barrier to suspended solids, most notably to the biomass providing the treatment within the bioreactor, resulting in a high quality solids free permeate which can either be sent as a low cost discharge to sewer, to water course or reused as a low grade source e.g. yard cleaning, or provided as a feed for further processing to potable water re-use. The AMBR LE™ process can produce treated water at less than 0.5 kWh/m3.
