Water. desalination + reuse

BUSINESS | 8 | Desalination & Water Reuse | February-March 2014 Yokogawa to provide control system for Jubail plant Yokogawa Middle East & Africa has received an order from Petroleum, Chemicals & Mining Company Limited (PCMC) to supply the control system for the SWRO-4 desalination plant, which is being built in Jubail, by the Power & Water Utility Company for Jubail & Yanbu (Marafiq). The plant under construction, SWRO-4, will utilize reverse osmosis membranes to desalinate seawater and will be able to produce 100,000 m 3 /d of potable water, said a Yokogawa statement. Yokogawa Middle East & Africa is responsible for the entire project, including the engineering and commissioning of these products. Delivery is scheduled for 2014, and the plant will start operation at the end of September 2014. CDM to build US$ 87 million Monterey desalination plant California American Water (Cal Am) has selected CDM Constructors Inc to design and build the seawater reverse osmosis (RO) desalination facility proposed as part of its US$ 320 million Monterey Peninsula Water Supply Project. CDM Constructors, confirmed on 24 January 2014 that its contract was worth US$ 87 million. The CDM bid was the lowest of the four proposers, with other proposals in the range US$ 90-110 million. "All four firms had some great technical concepts and innovations, but CDM Constructors' proposal scored highest overall in our team's ranking criteria," said California American Water's vice president of engineering, Rich Svindland. The contract is for design, construction and commissioning of the plant. It will include pretreatment filters; buildings for operations, RO process and electrical equipment, and chemical storage/feed facilities; washwater clarification, brine storage and pumping; and treated water storage and pumping. No mention is made in CDM's January release of the intake, for which Cal Am is examining subsurface slant wells. CDM Smith says the company ranked the highest on a combined business, technical and cost evaluation of four firms that submitted proposals during a 9-month procurement process. Design-build delivery was chosen for the facility to expedite the project schedule, streamline administrative processes and guarantee costs. Design of the project will begin immediately, with construction planned to begin in November 2015, and plant start- up is anticipated in mid to late 2017. The California Public Utilities Commission is currently reviewing Cal Am's application for the project and is scheduled to make a ruling on the application by August 2014. The Victor Valley Wastewater Reclamation Authority (VVWRA), on the edge of the Mojave desert in California, has selected FibrePlate™ hybrid-membrane™ technology manufactured by Fibracast Inc for two sub-regional membrane bioreactor (MBR) facilities. The MBR facilities will be located in high growth areas of the service region and produce a combined 2 MGD (7,570 m 3 /d) of high quality effluent for landscape irrigation. "FibrePlate membranes are a game- changing technology and they are the first 100% newly designed membrane that the industry has seen in a long time," said Andrew Benedek, executive chairman and chief technology officer of Canada's Anaergia, which owns Fibracast. "The hybrid-membrane™ combines the best advantages of hollow-fibre and flat-sheet technologies to deliver a significant capital and operating cost advantage to our clients." In 1980, Benedek founded Zenon Environmental, which developed ZeeWeed ultrafiltration membranes and was bought by GE in 2006. In addition to providing a drought- proof supply of water, the sub-regional MBR facilities will reduce the overall load on the collection system, enabling VVWRA to defer costly infrastructure expansion and reduce the energy costs associated with pumping recycled water. "This is a critical project that will help to ensure the future sustainability and economic prosperity of our communities," said Logan Olds, general manager of Victor Valley Wastewater Reclamation Authority. "We have a proven track record of employing best-in-class technologies to help solve critical wastewater infrastructure challenges. FibrePlate™ represents a new generation of membrane technology that offers unique operational efficiencies including future capacity expansion capabilities for the VVWRA." New hybrid membranes chosen for twin Victor Valley MBRs Doosan Hydro Technology has been awarded a US$ 10 million contract by Daelim Industrial Co Ltd for the industrial wastewater treatment and reuse package on the Saudi Elastomers Project (SEP) located in Al-Jubail Saudi Arabia. The SEP project, a greenfield synthetic rubber plant, is a joint venture between Saudi Basic Industries and ExxonChemical Arabia Inc. The contract awarded to Doosan Hydro includes the wastewater treatment system, comprising heat exchangers, membrane bioreactor, reverse osmosis and brine concentrator, plus the demineralized water treatment system for the utilities and offsite package secured by Daelim. The company says it is pleased to be working with Daelim on this project and has already completed a significant portion of the detailed engineering work. Doosan Hydro wins Al Jubail treatment
