LKY Prize Winner Views Industry Application Of His Technology At Sembcorp's Jurong Island Facilities

June 24, 2009

Lee Kuan Yew Water Prize 2009 (LKY Water Prize) Winner Professor Gatze Lettinga visited Sembcorp’s facilities on Jurong Island on Saturday, 20 June 2009, to view the industrial application of his award-winning water solutions in the treatment of complex wastewater.

Professor Lettinga was awarded the LKY Water Prize for his breakthrough of environmentally sustainable solutions for the treatment of used water using anaerobic technology.  His revolutionary treatment process enables industrial used water to be purified cost-effectively with reduced sludge and also the potential for the recovery of renewable energy.  By choosing not to patent his invention, he has made his technology universally available.

As a beneficiary of Professor Lettinga’s Upflow Anaerobic Sludge Blanket (""UASB"") technology, Sembcorp Industries currently operates four Expanded Granular Sludge Bed (""EGSB"") facilities and is the only company in Singapore to have applied EGSB technology. Sembcorp’s first two EGSB facilities are on Singapore’s Jurong Island petrochemical cluster. Operational since 1999 and 2001 respectively, they currently serve a total of 12 petrochemical and specialty chemical companies.

In 2002, Sembcorp exported its industrial wastewater treatment capabilities and set up another two EGSB plants in Zhangjiagang and Nanjing in China. These plants treat high chemical oxygen demand wastewater from industrial customers in the Zhangjiagang Free Trade Port Zone and Nanjing Chemical Industrial Park.
