MBR Order for Singapore’s Largest Wastewater Treatment Plant
First Delivery of Microfiltration Membrane for Large-Scale MBR to Hyflux

Mitsubishi Rayon Co., Ltd. (Head Office: Minato-ku, Tokyo; President: Masanao Kambara; hereinafter MRC) is pleased to announce that its microfiltration membrane (SADF membrane), for use with Membrane Bio-Reactor (MBR)-based treatment methods, has been adopted at Singapore’s largest wastewater treatment plant.

Nitto Denko Corporation (Head Office: Osaka, President: Yukio Nagira; hereinafter Nitto Denko) and its wholly-owned subsidiary Hydranautics (Head Office: California, U.S.A.; CEO: Minoru Kikuoka) won the order from Singapore firm Hyflux Ltd. for a microfiltration membrane (HYDRAsub, an MRC-made SADF membrane) for MBR use at Singapore’s largest wastewater treatment plant.

The plant will be built within the Jurong Water Reclamation Plant located in the Jurong District in the western part of Singapore. The treated sewage water to be reused by industries located on Jurong Island, and is scheduled to begin operation in the latter half of 2011.

In February 2008, MRC and Nitto Denko entered into a memorandum of understanding with Singapore’s Public Utilities Board over the development of a new water treatment method using membrane technologies, and have continued to conduct MBR verification tests in Singapore since June 2008. The results obtained through these verification tests led to the winning of this latest order.

Following this order for a large-scale MBR installation, we will further expand orders by combining microfiltration and reverse osmosis membrane technologies in the MBR market, which is expected to see increasing growth in the future.

Outline of the Order

1)	Plant site: Jurong water Reclamation Plant in Jurong,Singapore
2)	Order volume: Equivalent to 45,000ton/day as treatment capacity
3)	Start up Date: Latter half of 2011 (Scheduled)

Special Features of MBR technology

Membrane Bioreactor (MBR) is the combination of a membrane filtration process with the conventional activated sludge process used for treating conventional sewage and industrial wastewater. Because it makes settling pond unnecessary, the MBR process allows the generation of clean water with a facility with a smaller construction area than conventionally. MBR process has the following advantages.

1)	Reduced scale requirement: Conventional settling pond is unnecessary.
2)	High degree of treatment: Membrane filtration makes it possible to obtain water of reusable quality.
3)	Easy maintenance & upkeep: Compared to the conventional treatment process, there is no concern about sludge run-off, so that maintenance & upkeep is made easier.

Outline of the MRC Group Water Treatment Business and Future Policy

Mitsubishi Rayon Group has met more than 3,000 orders for hollow-fiber micro-filtration membrane units for sewage and wastewater treatment worldwide, particularly in Japan, China, and South Korea. As global leader in the Membrane Bio-Reactor (MBR) method, the Company is developing its wastewater treatment business using membranes. Our membrane technologies for MBR for large wastewater treatment plants are highly regarded. Looking ahead, MRC will not only supply membrane technologies, but also develop technologies for maintenance, operation and management systems for water treatment facilities. It will continue to focus on winning orders for large-scale projects, mostly overseas.

Outline of the Nitto Denko Water Treatment Business and Future Policy

Nitto Denko Group has a high achievement record to show in ultra-pure water production, seawater desalination and wastewater recycling, based on its world-class RO membrane technology platform. In the domain of RO membrane elements for creating pure water for industrial and public works use, Nitto Denko Group is a leading provider in that field.
The Group plans to enhance its activities not only in the RO membrane element area but also pretreatment applications for microfiltration and ultrafiltration, not to mention expansion into the MBR area and plant maintenance & upkeep businesses, in the growing markets of seawater desalination and wastewater recycling & reuse, to thereby offer total solutions to customers in the water treatment membrane business.
