Business Segments

We do Engineering, Procurement and Construction (“EPC”)

Through its EPC division, the Group provides engineering services which involve the design, fabrication, installation and commissioning of membrane-based water and wastewater treatment systems. The Group undertakes turnkey projects in the capacity of EPC contractor or as a membrane system specialist. We have an established track record in MBR especially in the chemical, petrochemical, municipal and industrial park sectors. 

As an EPC contractor, the Group has served major industrial clients such as petrochemical companies including China Petrochemical Corporation (“Sinopec”), China National Petroleum Corporation (“CNPC”), China National Offshore Oil Corporation (“CNOOC”) and Sembcorp Utilities. The Company also provided EPC solutions to industrial parks such as those in Guangdong (Huizhou, Nansha), Jiangsu (Dafeng, Taixin) and Tianjin (TEDA) and to local and municipal authorities in the PRC.

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.


We Invest

We invest in wastewater treatment projects via Transfer-Operate- Transfer (“TOT”) and Build-Own-Transfer (“BOT”) scheme of arrangements. These investments are typically backed by long term off-take arrangements by the Chinese government, over a period of 20-30 years, which provide us with a stable recurring cash flow. Our expertise in MBR technology allows us to secure industrial park wastewater projects that usually require higher treating standards. In addition, we also provide Operation and Management (“O&M”) services to third party treatment facilities for a fee. 

Our MBR technology background and strong track records has given us the competitive advantage to span our business across multiple provinces and cities in China.  To-date, we have more than 60 water treatment assets with a daily design capacity exceeding 6 million m3 per day.  

In addition, CEL invested in a fully-integrated environmental and utility company in Qingyuan City, Guangdong Province to undertake the supply of industrial water, steam and electricity, wastewater treatment and recycling services to the textile industrial park.  It also provides river restoration in Yixing, Jiangsu Province and in Ningbo City, Zhejiang Province; sludge treatment services in Weifang City, Shandong Province; and hazardous treatment services in Binzhou City, Shandong Province.

We Produce Membranes

After the acquisition of Memstar Technology Ltd. (“Memstar”) in April 2014, we now have our own membrane arm that specializes in manufacturing and application of polyvinylidene fluoride (PVDF) hollow fibre membrane and membrane products.  Memstar is equipped with strong R&D capabilities, backed by EDB and has technologically advanced manufacturing facilities located in both Singapore, China and USA.

It offers a range of pressurized and submerged membrane products and integrated membrane systems, including NIPS, TIPS, NF and RO membranes. It owns a suite of IPRs that include about 35 patents, manufacturing know-hows and proprietary production and product designs.
