The STERAPORE SADF hollow-fiber membrane units produced by Mitsubishi Rayon Engineering Co., Ltd. (a consolidated subsidiary of Mitsubishi Rayon) have been selected for use in upgraded facilities at Shiyan in China’s Hubei Province as part of a project to improve an important wastewater treatment plant under a national-level project. The remodeled facilities will have a total wastewater treatment capacity of 110,000 cubic meters per day, and will be one of the world’s largest facilities employing the membrane bioreactor (MBR) method.

Summary of Project:
To solve the chronic water shortage afflicting Northern China, Beijing is pushing through a massive plan known as the South-North Water Transfer Project, involving the construction of aqueducts to transport water northwards from the Yangtze River’s watershed area, where annual rainfall is relatively heavy.

The existing wastewater treatment facilities at the city of Shiyan in Hubei are located beside the Han River (a major tributary of the Yangtze that is intended to be used to supply water for the transfer project), upstream of Danjiangkou Reservoir. Construction of the facilities was completed in 2004. Now that the supply of water to Northern China has begun in earnest, fears have escalated regarding the quality of the water resources in the Yangtze watershed, which had been a cause of concern from the start. As a result, it has been decided to upgrade the treatment capabilities of the Shiyan plant through the installation of more advanced equipment.
The plant remodeling work currently being undertaken aims to divert 110,000 cubic meters per day (out of the total treatment capacity of 165,000 cubic meters) to new, upgraded facilities. Construction work is being undertaken by a Chinese contractor, and the facilities will employ Mitsubishi Rayon Engineering’s STERAPORE SADF hollow-fiber membrane units for the wastewater treatment. The upgrading project is scheduled for completion and start of operations sometime within 2009, when the facilities will become the one of the world’s largest employing the MBR method.
Mitsubishi Rayon Engineering has met more than 2,000 orders for hollow-fiber membrane units for sewage and wastewater treatment worldwide, particularly in Japan, China, and South Korea. The company is renowned as the world’s leading company in the field of MBR method wastewater treatment plants, and it plans to continue aggressively seeking out large-scale orders in overseas markets.
