Changi wastewater reuse plant goes commercial
Stage 1 of the Sembcorp Changi NEWater Plant (SCNP) in Singapore has started commercial operations, according to a 26 August 2009 announcement from Black & Veatch, who provided full design engineering for the wastewater reuse plant along with construction support and commissioning services.Ralph Eberts, senior managing director of Black & Veatch's Asia Pacific water business, said, "When Stage 2 is completed next year, SNCP will become one of the largest recycled water plants in the world, capable of producing a total of 228,000 m³/d (50 MIGD) of NEWater per day."
Sembcorp Industries, the plant owner, started to supply NEWater to PUB, Singapore's National Water Agency, on July 31. Stage 1 of the plant supplies Singapore with 69,000 m³/d of high-quality recycled water. Sembcorp was awarded the project in January 2008 and has an agreement to supply PUB for the next 25 years.
SNCP relies on advanced water treatment process steps, which include microfiltration, reverse osmosis and ultraviolet disinfection.
