One of the world’s largest vaccine producers, required a sewage treatment plant for its new pharmaceutical manufacturing facility, and decided to use a membrane bioreactor (MBR) based system over the conventional treatment, followed by media filters or ultrafiltration. Based in Pine, India, the facility had space limitations, and MBR was preferred due to its capability of minimizing foot-print while still producing high quality, ultrafiltration-grade water.
QUA had previously supplied EnviQ®, its submerged ultrafiltration MBR membranes, to the client for a polluted river water treatment plant. Based on the favorable performance, the client selected EnviQ again for its sewage treatment plant.
MBR systems are robust and can easily handle organic fluctuations. Since membranes are used as a physical barrier for solid-liquid separation, MBR systems typically deliver consistent high effluent quality in terms of TSS and organic removal, and also require less chemical for disinfection.
EnviQ ultrafiltration membranes are submerged, flat sheet membranes with a consistent pore size. These membranes are less prone to clogging, easy to operate and do not require any forced back wash. In addition, chemical cleaning of the membranes can be done while leaving them in place. A unique patented technology, EnviQ offers ruggedness of flat sheet membranes while consistently producing ultrafiltration quality water. Due to their lack of an external frame, the membrane cartridges are able to withstand harsh conditions while minimizing biofouling. These advantages are very valuable to the client’s treatment plant to meet continued expectations.
