•Case Study: MBR Technology From Siemens Helps The 2008 Games Go "Green"
Challenge
As part of its preparation for the 2008 games, the city of Beijing, China wanted to adopt eco-friendly transportation, power generation and water management technologies. One of their goals was to process 90% of the city's wastewater and re-use 50% of the treated effluent.
Solution
The Chinese government decided to expand the Beixiaohe Wastewater Treatment Plant's capacity from 40,000 to 100,000 m3/day. In June 2006, the Beijing Drainage Group awarded Siemens China a US$18.5 million contract to provide a 60,000 m3/day water reuse system for the Beixiaohe plant. The system includes a Membrane Bioreactor (MBR) system, which treats wastewater for reuse in the Olympic Village central area, fountains and lakes. The Drainage Group chose the Siemens MBR system because it is 60% smaller than conventional treatment technologies, and fit exactly in the plant's existing space. The MBR system contains biological and membrane treatment steps. With 4,864 membranes, the system is one of the largest of its kind in the world. Besides the MBR system, Siemens provided process design, mechanical equipment, electrical and automation systems, instrumentation, installation supervision and operation and maintenance training.
