MemPulse™ Membrane Bioreactor (MBR) System

The MemPulse™ Membrane Bioreactor (MBR) System uses a mechanical device that supplies irregular pulses of air to the MBR module.  This increases scouring effectiveness, decreases operation and maintenance costs, and reduces energy consumption.  The system can be used in with a wide range of municipal and industrial wastewater treatment applications.  It can also easily be retrofitted to existing plants wishing to replace conventional clarification processes with membrane separation.

The MemPulse™ device introduces air and mixed liquor into the bottom of the membrane modules through an "airlift effect".  The air bubbles blend with the mixed liquor and rise up into membrane fibers, providing effective scouring to the membrane surface and refresh the membrane surface to prevent solids concentration polarization.  The two-phase cross-flow reduces scour air energy dramatically.

No moving parts are added to the system, decreasing operation and maintenance costs.  Additionally, there are no mixed liquor jet laterals, which reduces installation time.  Rather, the MemPulse MBR device provides even distribution or air and mixed liquor ensures consistent operating conditions for the membrane modules.
