Sembcorp's Pioneering High Concentration Industrial Wastewater Treatment Business Expands to Nanjing

March 10, 2010

- Completes a second plant in China capable of treating high concentration wastewater without pre-treatment by customers

Sembcorp has successfully expanded its pioneering high concentration industrial wastewater treatment business in China, with the completion of a second plant in the country.  The 12,500 cubic metres per day plant in Nanjing will be capable of treating industrial wastewater, including industrial wastewater with a high concentration of up to 4,000 milligrammes per litre chemical oxygen demand.

This plant will be Sembcorp’s second in China to treat third party customers’ high concentration industrial wastewater directly from source without customers having to invest in pre-treatment facilities.  Government regulations usually require industrial companies to pre-treat their wastewater to a chemical oxygen demand of not more than 500 milligrammes per litre, before discharging the wastewater for treatment. The decision to permit industrial companies to discharge their wastewater directly to a facility, without needing the companies to pre-treat the wastewater signifies a new initiative by the government for advanced wastewater management in China.

Sembcorp’s earlier 15,000 cubic metres per day plant in the Zhangjiagang Free Trade Port Zone, was the first in China where industrial customers were allowed to do away with this pre-treatment step. This saved customers the resources required to build and operate their own pre-treatment facilities, and enabled them to concentrate on their core business. Opened in May 2009, the Zhangjiagang project leveraged on Sembcorp’s successful track record of effectively treating industrial wastewater in Singapore’s Jurong Island petrochemical cluster, and was selected as a government-to-government showcase project for progressive integrated water management. With the success of the Zhangjiagang plant, Sembcorp is now taking this high concentration wastewater treatment model to the Nanjing Chemical Industrial Park (NCIP).

The NCIP is the second chemical industrial park in China to be accorded State-level Chemical Hub status. Costing RMB 92.3 million (S$19.1 million), this new plant will meet the increasing customer demand for effective industrial wastewater treatment in the NCIP, where Sembcorp has existing water and wastewater treatment operations serving over 40 multinational companies and local enterprises. With this new plant, Sembcorp’s combined water and wastewater treatment capacity in operation and under development in China will total over 400,000 cubic metres per day.

Mr Tang Kin Fei, Group President and CEO of Sembcorp Industries said, “Sembcorp is very happy to celebrate this significant milestone for our water business in China. As a pioneer in the effective treatment of high concentration industrial wastewater in Singapore and China, we are pleased to now bring our effective solutions to customers in Nanjing.  These solutions save customers the need to invest in building and operating pre-treatment facilities for their wastewater, and at the same time, also support local authorities in their goal of environmental protection.”

The completion of the plant was celebrated in a ceremony today, graced Mr Mou Xiaoyu, Nanjing City Chief Secretary, Nanjing Chemical Industrial Park Vice Director, Mr Lu Yi, Sembcorp Industries Chairman Mr Peter Seah as well as members of Sembcorp Industries’ board.
