Product catalog summary
Overview
The Keppel Seghers Ulu Pandan NEWater Plant is Singapore's fourth and second-largest NEWater facility, producing 148,000 m3 of NEWater daily. It was designed, built, and is operated by Keppel Seghers under a 20-year Public Private Partnership with PUB, Singapore's national water agency. Officially opened in March 2007, the plant serves industrial and commercial sectors in Singapore's western and central regions.
Key Features
  • NEWater is ultra-clean water produced through a multi-barrier process involving microfiltration, reverse osmosis, and ultraviolet disinfection.
  • The plant uses advanced dual-membrane technology and ultraviolet light to treat used water, making it suitable for non-potable applications and freeing up potable water for other uses.
  • Construction was expedited using pre-fabricated steel bolted tanks, reducing the build time to 20 months.
  • Energy efficiency is enhanced with RO inter-stage energy recovery turbines and Variable Speed Drives (VSD) at all feed pumps.
  • The modular design allows flexibility in production changes with minimal disruption.
  • Space-saving measures include stacking RO modules higher than usual.
Process Flow
  1. Microfiltration: Treated secondary effluent is filtered through auto strainers and membranes to remove particulates, bacteria, and some viruses.
  2. Reverse Osmosis: A semi-permeable membrane filters out contaminants, producing water free from viruses and bacteria with low salt and organic matter levels. Energy recovery is achieved through a low-pressure interstage booster.
  3. Ultraviolet Disinfection: Ensures any remaining organisms are inactivated, and alkaline chemicals are added to balance pH.
  4. Quality Monitoring: A comprehensive system ensures compliance with PUB standards, including regular sampling and audits.
NEWater Quality Standards
  • pH: 7.0 - 8.5
  • Ammonia: <1 mg/l
  • Conductivity: <200 us/cm
  • Turbidity: <2 NTU
  • Total Organic Carbon (TOC): <0.1 mg/l
  • Total Residual Chlorine (TCL2): 0.5 - 2 mg/l
