PUB to build demo plant for testing water reclamation tech

SINGAPORE — National water agency PUB is building a demonstration plant to test cost-saving and energy-efficiency technologies that could be implemented at Tuas Water Reclamation Plant.

Slated for completion in February 2017, the tender for the demonstration plant was awarded to Mitsubishi Corporation last month.

Located within PUB’s water reclamation plant at Ulu Pandan, the fully automated demonstration plant will have a capacity of 12,500 cubic meters a day. It will be a training ground for operators and will also validate parameters for optimal used-water treatment. The water reclamation plant in Tuas will incorporate technologies that improve energy efficiency and manpower requirements.

The Tuas plant is key to Phase 2 of the Deep Tunnel Sewerage System, a network for the collection, treatment, disposal and reclamation of used water. Phase 2 of the sewerage system will cover the west of Singapore.

“These new and tested technologies will enable Tuas Water Reclamation Plant to be more eco-friendly, produce less sludge and have the capability of producing more biogas for power, while consuming lesser energy than conventional plants,” said PUB’s chief technology officer Harry Seah.
