Jacobs to design water reclamation plant in Singapore

0

Jacobs, an international engineering company, announced that it had been selected by PUB, the National Water Agency of Singapore, to design and oversee the construction and commissioning of one of the reclamation plants. largest and most advanced water tanks in the world.

The plant, Changi NEWater Factory 3 (CNF3), is the third NEWater factory to be located at Changi Water Reclamation Plant (WRP). CNF3 will be one of the first regeneration plants in the world to use membrane bioreactor (MBR) filtrate to feed reverse osmosis (RO) membranes. The use of MBR will improve the quality of treated wastewater for NEWater production and extend the life of RO membranes.

CNF3 will also incorporate water technology company ROTEC’s proprietary Reverse Osmosis Flow Reversal (FR-RO) technology into the RO system design to increase the recovery rate of NEWater from 75% to 90%. .

“Using a holistic and integrated approach not only helps Singapore meet its water needs, but also offers possible solutions for other countries around the world facing similar water security challenges” , said Steve Demetriou, president and CEO of Jacobs. “The CFN3 project is yet another way for Jacobs to address climate response and sustainability through innovative design.”

The design of CNF3 is underway and construction is expected to start later in 2022, with the plant expected to be completed in 2024. CNF3 will be owned and operated by PUB.

FR-RO technology has also been incorporated into the design of the Tuas Mega Water Reclamation Plant, which features an integrated NEWater plant, where Jacobs and ROTEC first collaborated after a successful demonstration project between PUB and ROTEC. CNF3 and NEWater plant in Tuas WRP will produce NEWater by passing MBR filtrate through reverse osmosis and ultraviolet disinfection.

NEWater is one of Singapore’s four national taps and a resilient water source. Jacobs was PUB’s delivery partner for Changi WRP Phase 1, which opened in 2009, and is currently working with PUB to deliver the Changi WRP Phase 2 expansion using MBR technology.

“We are excited to continue our working relationship with PUB and Jacobs by incorporating ROTEC’s proprietary flow reversal technology into the design of the CNF3,” said ROTEC CEO Dr. Noam Perlmuter. “Maintaining a sustainable flow through reverse osmosis membranes by inhibiting mineral scaling and limiting the potential for biofouling is key to reducing energy consumption and maximizing water recovery. . It’s good for PUB, Singapore and the planet.”
