Singapore：The World”s First Large Diameter SWRO Plant
This technical paper presents the engineering，procurement，construction，commissioning，and operations of a new SWRO desalination plant in Singapore.The desalination plant is the world”s first full-scale desalination plant to use large-diameter SWRO elements，and produces two customized grades of water for 10,000 m3/day of total production capacity：9,000 m3/day of high-grade service water，and 1,000 m3/day of domestic drinking water.The desalination plant was delivered as an engineer-procure-construct(EPC)contract，with CH2M HILL as the EPC contractor and PowerSeraya Ltd as the asset owner.The desalination plant is located on the site of PowerSeraya”s existing Pulau Seraya Power Station，a 3，000 MW power plant.CH2M HILL took advantage of the power station’S existing infrastructure of cooling water intake.discharge outfalls，and onsite tankage to CO-site the new desalination plant at the power station，resulting in an estimated 25 percent savings in capital costs for new infrastructure.The desalination plant is located on Jurong Island，a unique cluster of the major oil，petrochemical，and specialty chemical industries of Singapore.The desalination plant features Granular Media Filtration(GMF)pretreatment and a two-pass RO system.The RO system was supplied by GrahamTek Singapore Pte Ltd，and is the first full-scale installation in the world using large-diameter RO elements..The GrahamTek RO technology uses 16-inch spiral wound RO elements，incorporated with a patented integrated flow distributor and electromagnetic field(EMF)device.The GrahamTek RO technology claims advantages over conventional RO systems of：(a)capability to desalinate poorer raw water quality；(b)operation at higher fluxes and reduced footptints；and(C)reducing the likelihood of membrane scaling and need of chemical addition for scale control of sparingly soluble salts.The authors will present their experiences gained through the EPC，commissioning，and operations of this unique and innovative large-diameter SWRO plant.
