GE (NYSE: GE) introduces a new membrane bioreactor (MBR) with membrane accommodating carrier (MACarrier*) designed to help industrial companies meet stringent water discharge requirements and enable greater water reuse, while achieving cost savings and increased operating efficiency. Developed as a solution for tough-to-treat water, MBR with MACarrier combines a highly efficient MACarrier with GE’s ZeeWeed 500D membranes. This integration enhances the removal of recalcitrant organics and toxicity and can achieve a chemical oxygen demand (COD) reduction of more than 50 percent. The ability of the MACarrier to be biologically regenerated in the bioreactor cuts down on operational costs. The system combines three technologies: the MACarrier to enhance the removal of COD, toxicity, phenols and other contaminates found in wastewater, the bioreactor to remove suspended colloidal solids and reduce organic content and concentrations of nutrients, and membrane filtration as a physical membrane barrier to remove microorganisms found in wastewater.
