UEL’s membrane based advanced water treatment system has been used in water and wastewater treatment and wastewater reclamation. We have an established track record in MBR especially in the chemical, petrochemical and industrial park sectors. In the chemical and petrochemical sector, our largest MBR 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. Besides oil refining wastewater, our MBRs have been used by other companies under the Sinopec Group for treating wastewaters from different processing plants like caprolactam, PTA, polyethylene etc. Our MBR in industrial parks typically receives mixed industrial water from various tenants located in the industrial parks. 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. Our industrial park MBR at Taixing, Jiangsu, with a combined capacity of 70,000 m³/day, is the largest industrial MBR in Asia.

In October 2009, UEL was awarded a RMB 240 million contract to construct a 100,000 m³/day MBR at Jingxi Guangzhou for the Municipal Government of Guangzhou City. When the plant was completed in September 2010, it was one of the largest MBR plants in the world and the first and largest underground MBR plant in Asia.

Our CMF and RO systems are used mainly in wastewater recycling (NEWater application), especially in the area of industrial wastewater recycling. For example, our two projects for Sembcorp Utilities on Jurong Island at 5,000 m³/day each purify treated industrial effluent from different sources to various degrees of purity.

Our CMF+RO project in Sinopec Guangzhou Branch at a capacity of 7,200 m³/day was the first large scale membrane wastewater reclamation plant in Sinopec China to recycle wastewater from refinery.
