Membrane Bioreactor (MBR) - Plate UF membrane modules
In recent years, MBR plants using low-pressure submerged membranes have become more cost effective and the state of the art technology for treating wastewater. The combination of an activated sludge process and membrane technology removes carbon, phosphorous, nitrogen, certain toxins (carcinogenic, mutagenous, and hormonally active) and bio-accumulative micro-contaminants. Pollutants that cannot be eliminated by a membrane bioreactor can be eliminated by post-treatment such as nanofiltration or reverse osmosis. Nitrogen and phosphorous removal are dependent on the plant layout: Arrangement of the anoxic / aerobic basins, chemical addition for phosphorous removal, and carbon addition for a secondary anoxic basin.
The primary role of the membrane is to act as a selective barrier to eliminate fine particles up to dissolved matter from water and wastewater. A3's unique module design offers one of the most compact and efficient plate membrane modules on the market. Our plate ultrafiltration modules use flat sheet membranes arranged in parallel with a pore size less than 0.04 μm.
