SINGAPORE: National water agency PUB is building a demonstration-scale Integrated Validation Plant to test technologies that could potentially be implemented at the future Tuas Water Reclamation Plant.

In a press release on Monday (Sep 7), PUB said these technologies are aimed at enhancing cost savings and energy efficiency of the used water treatment process at the Tuas Water Reclamation Plant.

Slated for completion in February 2017, the demonstration plant will allow PUB to validate the efficacy of the new process innovations planned for the future Tuas plant. The tender for the plant was awarded to Mitsubishi Corporation last month, it added.

Located within PUB’s Ulu Pandan water reclamation plant, the demonstration plant with a capacity of 12,500 cubic meters a day will be designed to be a fully automated plant to reduce the manpower required to operate the plant. It will also serve as a training ground for the operators and to validate parameters for optimum used water treatment, it added.

"The demonstration plant is a living model of the future Tuas WRP to allow us to test and validate the new technologies that will eventually be used at the Tuas WRP. These new and tested technologies will enable Tuas WRP 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 Chief Technology Officer Harry Seah.

PUB to build demo plant for testing water reclamation tech
Today Online 8 Sep 15;

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.

Construction of the demonstration plant, located within PUB's existing Ulu Pandan Water Reclamation Plant, starts this month and will be done in February 2017.

The demonstration plant will have a capacity of 12,500 cubic m a day, a fraction of the 800,000 cubic m of used water treated daily at the existing Changi Water Reclamation Plant.

While its capacity is relatively small, the fully automated demonstration plant will have all the functions of a typical water reclamation plant.

It will test new water treatment technologies, such as the use of a unique type of bacteria to remove fine particles in used water. It will also be used to train operators of the new technologies.

Mr Harry Seah, PUB's chief technology officer, said in a press release yesterday: "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 less energy than conventional plants."

The Tuas Water Reclamation Plant, whose completion date has not been confirmed, is a key part of Phase 2 of the Deep Tunnel Sewerage System, an extension of the underground "super highway" carrying Singapore's waste water through sloped tunnels to used water treatment plants.

To be ready by 2022, the extension will carry used water from western Singapore - including the city area - to the Tuas plant, where the water will be treated before it is pumped out to sea or reclaimed as Newater, with the purified water mainly for industrial use.
