Advertorial Siemens Water Technologies TECHNOLOGYPROFILE MemPulse™ Membrane Bioreactor (MBR) System F inally, efficiency meets simplicity. The new MemPulse™ membrane bioreactor (MBR) system from Siemens Water Technologies incorporates innovative technology designed to increase dependability, decrease operating and maintenance costs, and dramatically reduce energy usage. What it is The MemPulse™ MBR is a wastewater treatment system that combines one of Siemens’ proven activated sludge biological treatment processes with an immersed membrane system. This advanced system supplies continuous air into a new innovative technology, and through accumulation techniques produces random pulses of air into the base of the module, resulting in increased scouring effectiveness, decreased operation and maintenance costs and dramatically reduced energy consumption. It can be used in a multitude of municipal and industrial wastewater treatment applications, and also allows for simple retrofitting to existing systems. How it works The innovative MemPulse™ MBR device uses air accumulation techniques to produce an irregular pulse of air, and through an “airlift effect” mixed liquor is drawn into the base of the module with the air. This two-phase flow rises up into membrane fibers in a cross-flow pattern, providing effective scouring to the membrane surface and refreshing the membrane surface to prevent solids concentration polarization, drastically reduces energy associated with air scouring. Additionally, there are no mixed liquor jet laterals or added moving parts, reducing operation and maintenance costs and installation time. The MemPulse™ MBR device provides even distribution of air and mixed liquor, ensuring consistent operating conditions for the membrane modules. Siemens Proven MBR Technology The MemPulse™ MBR combines one of Siemens’ proven activated sludge biological treatment processes with a robust immersed membrane system. The Envirex® biological process solutions of Orbal®, VLR® and Cannibal® are available in different configurations and customizable to fit your wastewater treatment needs, providing exceptional solids reduction, nitrification-denitrification, phosphorus removal and stormwater treatment. SmartMBR™ Controls are integrated into the MemPulse™ MBR solution, offering capabilities unmatched by other available systems and delivering unparalleled performance enhanced by system reliability. This combination provides: • Dependable process performance backed by guarantee • Absolute minimum power costs • Reliable hands-free operation and reduced operator attendance Features and Benefits of the new MemPulse™ MBR • Reduction in energy costs by 30-40 percent over conventional MBR processes • High effluent quality in a small footprint • Maximum automation, minimal operator requirements and guaranteed system reliability made possible by SmartMBR™ Controls • Low effluent turbidity and significantly reduced sludge yield • Expert process support for design and integration • Greater than 90 percent biosolids reduction with Cannibal® (800) 525-0658 or (724) 772-1402 information.water@siemens.com www.siemens.com/mempulse JANUARY2009 www.pollutionengineering.com 43 http://www.pollutionengineering.com
