Unprecedented Agreement between Japanese and Chinese Private Sectors -
TOKYO–(Business Wire)–
Teijin Limited (TOKYO:3401), announced today that it has signed a business
collaboration agreement with Yixing City Water Works & Construction Investment
Co., Ltd., which manages water supply and sewage systems for the city of Yixing,
Jiangsu Province, to co-develop wastewater treatment systems for rural
communities.
The agreement was formed in cooperation with Membrane-Tec Co., Ltd., a Japanese
manufacturer of membrane filtration units for water treatment. The three parties
were brought together through an environmental business support program
organized by the city of Osaka to promote collaborative efforts between Japan
and Jiangsu Province. The agreement marks the first time that private companies
from Japan and China will collaborate to improve wastewater treatment in rural
communities.
A small pilot system will be tested in the village of Dagang this June, aiming
at full-scale operation sometime during fiscal 2010 (ends March 31, 2011). The
system incorporates Teijin’s Multi-stage Activated Biological Process (MSABP)
wastewater treatment technology and Membrane-Tec’s membrane filtration
technology. The city of Yixing began installing drainage pipes from homes last
December and plans to complete this preparatory step by late May. Teijin and
Membrane-Tec have finished the detailed design of the pilot system.
Yixing is located on Taihu Lake, one of China’s largest lakes and an important
source of water for surrounding cities. Due to rapid economic growth, however,
the river basin fed by the lake has become polluted, particularly by influent of
untreated drainage from nearby communities. Under a national policy to upgrade
rural environments, Yixing plans to address the problem by constructing drainage
system under the management of Yixing City Water Works & Construction
Investment.
As part of its Green Chemistry businesses for the creation of environmentally
friendly technologies, Teijin is developing solutions for wastewater treatment
and recycling. Pilot plant studies are underway including testing the
innovative, highly efficient MSABP technology in locations around the world.
The MSABP system uses biological carriers with high concentrations of
microorganisms in multi-stage aeration tanks. Organic excess sludge is
eliminated as part of a biological food chain created with the system, and
operational control is simple. The result is a sludge-free, low-maintenance,
energy-saving and low-cost solution. Moreover, the system helps to reduce CO2
emissions that otherwise would have been generated by transporting and
incinerating the sludge.
Going forward, Teijin will continue to develop unique, comprehensive wastewater
treatment solutions based on not only MSABP but also composite electrocatalytic
(ELCAT) and advanced oxidation water treatment (HiPOx) technologies, aiming to
promote increased wastewater reuse, energy conservation and CO2 emission
reduction worldwide.

About Membrane Filtration Technology by Membrane-Tec
The technology uses a membrane bioreactor process, which combines membranes and
conventional activated-sludge treatment to simultaneously separate solids from
liquids while treating the sludge organically to obtain clean water. The fibrous
PTFE (polytetrafluoroethylene) membrane enables energy savings and low
maintenance through the use of uniform hole diameters and low trans-membrane
pressure to prevent tearing.
