Energy-efficient R&D projects

Some of the R&D projects that have reached significant milestones include: low-energy desalination technology; a membrane bioreactor (MBR) testing facility for validating new design parameters; and a new micro-media column for high-purity water production.

At SIWW, the MemPulse Membrane Bioreactor (MBR) system will also be featured. A key technology for water reuse applications, this system uses a mechanical device that supplies irregular pulses of air to the MBR module, which increases scouring effectiveness, decreases operation and maintenance costs and reduces energy consumption by 30-40 percent over conventional MBR processes. It can also be easily retrofitted to existing plants that need to replace conventional clarification processes with membrane separation.

Energy consumption alone accounts for about 30% of municipal water treatment operating costs. At SIWW, Siemens will showcase energy efficient technologies and processes such as the BioFlowsheet+ process optimisation program. This program integrates several key wastewater operations, including biological, solids separation, solids treatment and controls to significantly reduce energy costs. Utilities also strive to increase plant capacity and maintain a continuous water supply. The Siwa product family provides modular solutions that have been especially developed for water supply and wastewater treatment. Their focus is on electrotechnical equipment for water transport pipelines and desalination plants, applying reverse osmosis. The portfolio encompasses systems and individual project solutions, including pipeline management, leak detection, automation packages and services for the life cycle of the plant.

Singapore International Water Week is a global platform for water solutions that brings policy makers, industry leaders, experts and practitioners together to address challenges, showcase technologies, discover opportunities and celebrate achievements in the water world. The event’s flagship programs comprise the Lee Kuan Yew Water Prize, Water Leaders’ Summit, Water convention, Water Expo and Business Forums. Themed “Sustainable Water Solutions for a Changing Urban Environment,” the 2011 edition will address the latest and most pertinent water issues amid a rapidly changing world.
