Siemens (Tianjin) Water Technology Engineering Co. Ltd. (SWTE) has received an order from Shenzhen Zhongying Precious Metal Co. Ltd. worth several million US dollars. In the scope, Siemens will provide a wastewater treatment system capable of handling 9,000 tons per day of domestic wastewater for Shenzhen Lilang International Jewellery Industry Park (SZLIJIP). The solution will use Siemens advanced MemPulse membrane bioreactor (MBR) system. This engineering project will be the first of its kind for Siemens in China with underground MBR construction from a private-owned investment enterprise. The wastewater treatment system is scheduled to start up by mid of 2011.
"This is another successful MBR project right after Beijing BeiXiaoHe Wastewater Treatment Plant, and Wuxi XinCheng Wastewater Treatment Plant MBR project. The Zhongying MBR project proves Siemens’ technology advance and competitiveness on MBR systems”, said Alfred Ng, General Manager of Water Technologies of Siemens Ltd., China.
Membrane bioreactor systems combine the advantages of traditional biological treatment with membrane treatment process. Compared to traditional treatment processes, MBR systems can provide reduced land area, improved effluent quality and reduced sludge output. The MemPulse MBR system represents the latest in advanced water treatment technology: Instead of introducing air continuously to the membrane modules, the MemPulse system uses a mechanical device that supplies irregular pulses of air to scour the membranes. This reduces the aeration system energy consumption and decreases operation and maintenance costs.
As a significant construction project in Shenzhen, SZLIJIP covers land area of 120,000 sqm (construction area 530,000 sqm) with total investment of about 200 million US dollars. It is the biggest jewelry industry base in China covering, among others, jewelry processing, manufacturing, exposition, auction, wholesale and international trading. SZLIJIP incorporates environmental friendly and low carbon-emission design through an international environmental engineering consultant company for the overall industrial park planning and detailed engineering design works.
The MemPulse membrane bioreactor (MBR) is part of Siemens’ Environmental Portfolio. In fiscal 2010, revenue from the Portfolio totaled about €28 billion, making Siemens the world’s largest supplier of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by 270 million tons, an amount equal to the total annual CO2 emissions of the megacities Hong Kong, London, New York, Tokyo, Delhi and Singapore.
