Considering clients requirement of high degree of treated water quality considering reuse of treated water for secondary production applications the Submerged Membrane Bio Reactor process technology was selected. The advantage of submerged MBR process is that it not only produces high quality treated effluent but also protects post treatment unit of reverse osmosis membranes from impurities such as TSS, and organic matter.
The submerged membranes used were manufactured in USA and successfully installed and commissioned by Sparkle. Final stage treatment was carried out using RO for elimination of TDS from wastewater. The treatment steps summarized are as below:
