Singapore’s PUB selects DuPont MBR and RO technology for water reuse plant

PUB, Singapore’s National Water Agency and its water infrastructure contractor UES Holdings Pte Ltd have selected DuPont to implement its MemPulse MBR and FilmTec RO technologies for the sustainable production of NEWater at the landmark Tuas Water Reclamation Plant.

DuPont MemPulse membrane bioreactor system (MBR) and FilmTec reverse osmosis (RO) technologies have been selected  as part of a multi-technology solution for Singapore’s Tuas Water Reclamation Plant (WRP), which is currently under construction as part of PUB’s Deep Tunnel Sewerage System Phase 2 project. The new facility is planned to start initial operations in 2026 and will be one of the world’s largest MBR facilities when fully completed.

“Over the last 20 years, Singapore has been an international trendsetter in water reclamation. NEWater, its third National Tap, has helped to educate people about the benefits of recycled water and how reuse is proving critical to helping the country strengthen its water resilience in the face of climate change ,” said Alan Chan, Global Vice President and General Manager, DuPont Water Solutions. “Our MBR and RO products are now set to be at the heart of the pioneering Tuas plant, supporting the sustainable production of NEWater to enhance the sustainability of Singapore’s water supply.”

Once fully operational, the Tuas WRP will have the capacity to treat an average dry weather flow of 650,000m3/day of domestic wastewater using an advanced multi-technology process; MBR and low-fouling RO elements will make it more energy-efficient to further purify the treated wastewater and produce NEWater.

“DuPont has a long-term commitment to Singapore, and we are very proud to see our technology deployed as part of such an internationally significant project,” said Kee Hoe Ng, Project Sales Leader, DuPont Water Solutions. “Our MemPulse MBR technology is being used across the globe to create stable membrane environments with automated membrane cleaning systems that reduce maintenance requirements and total lifecycle costs.”
