Membrane bioreactors (MBR) are one of the most efficient biological wastewater treatment systems. The biomass retention via membrane technology leads to a small footprint, high treatment performance and germ-free outlet. The WEHRLE BIOMEMBRAT® high-performance MBR has proven its reliability for over 25 years in more than 300 projects worldwide. Compared to conventional MBR’s with submerged filtration, WEHRLE’s MBR excels in robustness and flexibility, also in case of highly loaded wastewaters
