[Company Information]Japanese Alliance to Enter into Joint Development in Singapore with PUB
- Nitto Denko & Mitsubishi Rayon Engineering Sign Memorandum with PUB for Developing Wastewater Reclamation Technology Based on Separation Membranes -
2.19.2008
Japan’s leading diversified materials company Nitto Denko Corporation (Nitto) and Mitsubishi Rayon Engineering Co., Ltd. (MRE), one of Japan’s Mitsubishi Rayon Group companies, have jointly entered into a Memorandum of Understanding with Public Utility Board (PUB), a branch of the Singaporean government responsible for water administration, for a joint development of wastewater reclamation technologies using separation membranes, the two Japanese partners announced today.
Under the basic agreement reached this time, Nitto and MRE who had jointly established a water treatment R&D technology company called Kathyd Technology LLC (Kathyd) in the U.S in June 2007, will provide, via Kathyd, their membrane bioreactor (MBR) technology for treating activated sludge as well as reverse osmosis (RO) membrane technology for a large-scale water reclamation facility to be constructed in Singapore in future. At the same time, the two companies together with PUB will embark on the development of a technology offering superior economics for the maintenance, operation and administration of these membrane separation systems.
Background
In 2000, Singapore Government had entered into a demonstration plant project aimed at establishing a wastewater reclamation technology (NEWater Project) using separation membranes, as part of Singapore’s national policy to ensure the security of valuable water resources. Nitto had subsequently contributed to the successful conduct of the NEWater Project by providing to PUB, through Nitto’s U.S. water technology subsidiary Hydranautics (HYD), the “low-fouling RO membrane” elements which Nitto and HYD had developed ahead of the world for wastewater reclamation, together with the operation & maintenance technology for the elements.
Since then, Nitto had furnished to PUB a series of Nitto/HYD’s low fouling and low energy membrane products as well as their operation & maintenance technologies, to develop a close relationship with PUB. Currently 80% or more of NEWater generated by PUB is produced using Nitto/HYD’s RO membranes.
| Name of Project |
Plant capacity (m3/day) |
Plant startup (year) |
RO element quantities (pcs) |
RO element supplier |
|---|---|---|---|---|
| Bedok Demonstration Plant |
10,000 | 2000 | 624 | Nitto Denko /Hydranautics |
| Bedok | 32,000 | 2002 | 2,044 | Nitto Denko /Hydranautics |
| Kranji Phase I | 40,000 | 2002 | 2,555 | Nitto Denko /Hydranautics |
| Ulu Pandan | 156,000 | 2006 | 9,100 | Nitto Denko /Hydranautics |
| Seletor | 24,000 | 2003 | 1,500 | Company A |
| Kranji Phase II | 16,000 | 2006 | 1,022 | Company B |
MRE, on the other hand, has been very highly evaluated by PUB for its microfiltration membrane (MF) performance, having put into operation an MBR-based test plant at Bedok Sewage Treatment Works, Singapore, in 2003. With many references in terms of supplying large-scale MBR facilities around the world, MRE has been strongly requested by PUB to take part in a joint development effort.
The two partners have decided to partner with PUB in the joint development program this time, with the hope of leveraging their respective strengths, in view of the following. Namely, PUB plans to evolve the wastewater reclamation technology using separation membranes into a more superior technology combining MBR and RO demonstrating better economics and better quality of reclaimed water, and such plans match the product development direction the two companies are pursuing.
