Challenging the Status Quo in MBR: Chemical Free Operation

MBR technology has already become the new status quo for municipal waste water treatment plants.

The possibilities of using membrane technology for trace substance elimination, biological purification of substances such as pharmaceuticals as well as industrial chemicals, and the optimisation of the overall biological process in MBR technology are now being investigated on a broad front.

The newly developed 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 specifically, the BIO-CEL®-MCP process utilising granulates to mechanically clean the membranes has been developed. 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 (or the output of an existing BIO-CEL® installation increased) but also the required volume of the filtration tanks will be significantly 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.
