Unlock MBR potential: Tailor mixed liquor through selective wasting & densification Membrane Bioreactors (MBR) are normally operated with uncontrolled MLSS (Mixed liquor suspended solids) characteristics which limits the full potential of MBR performance. ZeeWeed MBR with zeeDENSE is an innovative technology that combines ZeeWeed MBR with continuous flow densification to optimize membrane and biological performance. ZeeWeed MBR with zeeDENSE reduces operating cost by tailoring mixed liquor characteristics to optimize membrane & biological performance. Benefits include: Membrane Performance Reduced colloidal fouling Reduced membrane cleaning Improved sludge filterability ZeeWeed MBR with zeeDENSE uses a hydrocyclone to separate activated sludge into a dense and light fraction. The dense fraction is returned to the biological process and the light fraction is discharged to solids treatment. The result is selective wasting of bacterial populations that negatively impact MBR performance and retention of densified biomass fractions that improve biological and membrane performance. Increased permeability Optimized performance over the life of the membranes Biological Performance Increased resilience Biological phosphorus removal optimization Nuisance foam elimination ZeeWeed MBR with zeeDENSE can be used for a range of applications: Municipal - optimizing membrane & biological nutrient removal performance Industrial - improved biological resilience and membrane performance Upgrade of existing MBR plants - retrofit into existing MBR plant operation
