PUB and Mitsubishi join to test water recycling technology

Singapore’s national water agency, PUB. has contracted Japan’s Mitsubishi Corporation to build a demonstration-scale plant to test energy saving technologies that may be deployed at the proposed Tuas Water Reclamation Plant (WRP).

The 12,500 m³/d, fully automated demonstration plant will assess new technologies which, along with established technologies, PUB anticipates will enable the planned Tuas facility to produce less sludge and produce more biogas for power generation while consuming less energy than conventional plants.

The demonstration plant, sited within PUB’s Ulu Pandan WRP, will also be a training facility for operators and serve to validate parameters for optimum used water treatment. MHI said that with this project, it will continue to work to advance its water treatment and recycling technology to grow its water treatment business globally.

The tender for the plant was awarded to Mitsubishi Corporation last month. Mitsubishi Heavy Industries Asia Pacific (MHI) has been contracted by Mitsubishi Corporation to construct the plant. The plant is scheduled for completion in February 2017.

The Tuas WRP will be the key component of a the second phase of a giant network for the collection, treatment, disposal and reclamation of used water – the Deep Tunnel Sewerage System. The second phase of the DTSS will extend the system to the west of Singapore island.

MHI and PUB signed a memorandum of understanding in 2012 to collaborate on a test project at Jurong WRP to treat industrial used water.
