PUB, Singapore’s National Water Agency, and its water infrastructure contractor, UES, has selected American multinational chemical company DuPont Water Solutions to implement its MemPulse membrane bioreactor (MBR) and FilmTec RO technologies for the production of NEWater at Tuas Water Reclamation Plant (WRP).
DuPont’s multi-technology wastewater recycling solution was selected as part of a multi-technology solution for implementation in Singapore’s Tuas WRP, which is currently under construction as part of PUB’s Deep Tunnel Sewerage System (DTSS) Phase 2 project. This new facility is planned to commence initial operations in 2026 and is poised to become one of the world’s largest MBR facilities.
“Over the last 20 years, Singapore has been a trendsetter in water reclamation. NEWater, its third national tap, has helped educate people about the benefits of recycled water and water resilience in the face of climate change,” said Alan Chan, DuPont’s global vice-president and general manager.
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 purify treated wastewater and produce NEWater.
Kee Hoe Ng, DuPont’s project sales leader said, “MemPulse MBR technology is used across the globe to create stable membrane environments with automated membrane cleaning systems that reduce maintenance requirements and total lifecycle costs.”
