Our Track Records
Among the membrane technologies, the Group’s principal treatment technology is Membrane Bioreactor (“MBR”), which is typically applied in the treatment of various wastewater types. The Group has an extensive track record of applying MBR technology successfully in wastewater treatment, and particularly in the treatment of industrial, chemical and petrochemical wastewater. The Company has built up a track record with more than 100 MBR references in various parts of the PRC and in Southeast Asia.
Examples are the 25,000 m3/day plant at Huizhou Daya Bay Petrochemical Hub and the 10,000 m3/day plant at Guangzhou Nansha Chemical Industrial Park. In the 70,000 m3/day Taixing treatment plant, the Group’s EPC division built one of the largest industrial MBR plants in Asia.
The Company’s largest MBR in the chemical and petrochemical sector, in terms of capacity completed to date, is the 15,000 m3/day oil refinery wastewater treatment system for CNOOC’s first onshore refinery at Huizhou, Guangdong. In September 2010, the Company completed a 100,000 m3/day municipal MBR plant at Jingxi Guangzhou and it was one of the largest MBR plants in the world and the first and largest underground MBR plant in Asia at the time of completion.
In 2015, the Group completed the construction of a 200,000 m3 /day municipal wastewater treatment plant in Fuzhou City, Fujian Province, China. The plant, valued at RMB580 million, is one of the largest wastewater treatment plants using the MBR technology in China.
In 2016, CEL completed the upgrading and expansion of four wastewater treatment plants with a total capacity of 750,000 m3/day in Chengdu Province, using CEL’s proprietary MBR technology to meet category 4 surface-water discharge standard without additional land use and work stoppage.
In addition, the Group also completed the upgrading and expansion of the Gaoyang industrial wastewater treatment plant with the capacity of 200,000 m3/day in Hebei Province to meet the higher discharge standard with Chemical Oxygen Demand (“COD”) ≤ 40 mg/litre.
