The mechanical cleaning process (MCP) for membrane bioreactors (MBR) is the latest innovation of waste water treatment processes. One of the biggest challenges of membrane bioreactors compared to conventional waste water treatment plants is the relatively high energy demand of MBR systems.
In order to optimise MBR systems regarding the energy demand, Microdyn-Nadir developed the BIO-CEL-MCP process utilising granulates to mechanically clean the membranes. The MCP process also allows for an almost chemical-free operation and even more importantly a significant enhancement of flux. In turn, not only the membrane area required can be reduced, but also the required volume of the filtration tanks will be smaller. Hence, the overall energy consumption can be reduced substantially. Studies show that the mechanical cleaning process can result in savings in energy and chemicals of up to 27 %. In addition, when using an MBR with MCP the process stability as well as the operational safety are increased.
