business August-September 2015 | Desalination & Water Reuse | 7 | Hyflux wins container desalination deal worth US$ 48 million in Saudi Arabia Desalination specialist, Hyflux, has won a US$ 48 million contract to build a containerized desalination system for Saudi Arabia. The Saudi state-owned Saline Water Conversion Corporation (SWCC) awarded the deal to wholly- owned Hyflux subsidiary, Hydrochem Saudi, to design, build and supply a 30,000 m³/d containerized desalination system. The system will be located on the site of the existing Yanbu Desalination Plant on the Red Sea coast, 350 km north of Jeddah. It will augment the Yanbu plant's capacity to ensure a continuous supply to the industrial city of Yanbu and the nearby Medina region. Under the contract, Hyflux will build ten, 3,000 m³/d containerized units that will deploy its Kristal ultrafiltration membrane technology. Hyflux executive chairman and group chief executive officer, Olivia Lum, said: "This project is a great example of Hyflux's ability to provide quick, cost-effective solutions for our customers." The project is scheduled for completion in about eight months. The announcement of the contract win followed a recent forecast by Lum of an end to a lengthy doldrums in desalination business in the Middle East. Hyflux more recently picked up a US$ 250 million contract to design, build, own and operate an independent water project (IWP) in Qurayat in Muscat governorate. Oman. She predicted that the political uncertainty that has curbed water treatment growth in the in the Middle East was about to cave in under the power of demand: "Pent-up demand in the Middle East and Africa is driving the revival of water infrastructure projects," said Lum. ContRACt&tenDeRneWS Oasys continues its bullish in China programme US-based forward osmosis specialist, Oasys Water, has unveiled the latest advance in its bid to expand in China with its partner in the region, Beijing Woteer. Oasys is to supply its membrane brine concentrator (MBC) and reverse osmosis technologies as part of Woteer's build-own-transfer (BOT) project to construct an integrated zero liquid discharge (ZLD) set up serving a chemicals-from-coal plant. The plant is in the coal capital of western China, Taiyuan Qing Xu Economic and Technology Development Zone. Oasys' chief executive officer Jim Matheson said he foresees further growth in opportunities from ZLD deployment: "The industrial ZLD market in China continues to expand rapidly and Oasys and Woteer plan additional project announcements in the near future," he said. "The BOT model is of increasing interest to customers, but also some of the leading Chinese engineering, procurement and construction companies such as Woteer, and will be increasingly common in the future," Matheson added. According to Oasys, its MBC system at Taiyuan will be "part of an integrated ZLD wastewater treatment train treating a combination of streams from the boiler makeup water plant with total feed volumes expected at 1,200 m³/day". Oasys summarized the process as "pretreatment followed by microfiltration and ion exchange polishing leading to a pre- concentrating reverse osmosis system that feeds the Oasys MBC." Oasys said the MBC target recovery was greater than 70%, concentrating the post-RO feed stream from about 75,000 ppm in total dissolved solids to some 240,000 ppm. "This highly concentrated brine from the MBC system will feed a crystallizer to complete the integrated ZLD process," said Oasys. Spain's Acciona pulls in US$ 0.5 billion deal pair Spanish firm, Acciona Agua, has won two major desalination contracts in Qatar worth US$ 525 million as part of a joint venture with Mitsubishi Corporation and Toyo Thai Corporation. Acciona and its partners will design, construct, operate and maintain the 164,000 m³/d Ras Abu Fontas 3 reverse osmosis desalination project. And the Spanish company has won a separate 284,000 m³/day desalination plant contract as part of an independent water and power project being developed by Mitsubishi at Umm Al Noul and worth about US$ 225 million to Acciona. Subsequent to its start up, water production at the site will be increased to more than 600,000 m³/d Acciona said. Water producer, Qatar Electricity and Water Company, awarded the Ras Abu Fontas contract and the off-taker will be utility, Qatar General Electricity and Water Corporation. The US$ 300 million project will include a 10-year operation and maintenance contract for Acciona. It will be Qatar's first large-scale, membrane-based desalination plant.
