BIO-CEL®-MCP

Mechanical Membrane Cleaning for BIO-CEL® MBR Modules

The membrane bioreactor (MBR) process is the most advanced wastewater treatment process currently available. The submerged BIO-CEL® membrane modules replace space-intensive secondary clarifiers and safely separate the purified wastewater from the biomass. Membrane bioreactor systems offer many advantages over conventional systems, namely the excellent effluent quality and minimal footprint.


Besides the process-integrated aeration (crossflow along the membranes) and periodic back flushing/relaxation phases, chemical cleaning may also be used to reduce the fouling layer. The chemicals effectively clean the membrane surface of the BIO-CEL® Membrane Bioreactor (MBR) module, thereby restoring its original permeability and enabling stable and reliable process operation.

 

Reduction of operating costs through Mechanical Cleaning (MCP) of the BIO-CEL® MBR Module

 

As a further process-integrated feature, the BIO-CEL® membrane module can also be cleaned mechanically, through the use of the patented BIO-CEL® MCP (Mechanical Cleaning Process), to help reduce operating costs. Long term experiences show, that an almost chemical free operation is possible. This innovative process reduces the formation of a fouling layer. The membrane cleaning process is supported by the crossflow aeration and the cleaning efficiency of inert, organic material (MCP granulate). 

 

Continuous membrane cleaning during operation of the BIO-CEL® MBR module

 

The MCP granulate is added directly into the activated sludge. The airflow induced by the module-integrated membrane aeration system draws the MCP granulate up between the BIO-CEL® MBR module´s membrane sheets. As the MCP granulate rises, the membrane area is continuously cleaned through the direct contact of the granulate with the sludge on the membrane surface.

The fouling layer formed during the filtration 
process can be removed reliably without compromising the functionality of the membrane. In the downstream area outside the membrane modules, the current cause the granulate to move back to the base of
 the module where it enters again into the upstream flow. The MCP granulate has been designed for permanent use. It is retained in the filtration tank by 
suitable separation systems.

 

Higher specific flows – less membrane area needed – lower investment and energy demand

 

The BIO-CEL® MCP system enables much higher specific flows. This lowers investment costs (smaller membrane area needed) and reduces energy consumption (crossflow) for the entire system.



This mechanical cleaning technology can only be used in conjunction with the BIO-CEL® module because of their flexible sandwich structure. Other module types do not incorporate the required constructional and hydraulic characteristics to perform a mechanical cleaning. The membrane laminate´s self-supporting structure enables chemical cleaning as well as mechanical cleaning of the membrane surface, thereby ensuring permanently high membrane system availability.
