BUSINESS Veolia to build Saudi's largest UF/RO plant The largest ultrafiltration (UF) and reverse osmosis (RO) plant in Saudi Arabia is to be built for Marafiq, the country's leading water and electricity services operator, by Veolia Water. With a capacity of 178,000 m3/d, the plant will supply the Sadara petrochemical complex built by Dow Chemical and Saudi Aramco in Jubail Industrial City II and is due to come on stream in June 2015. The water will be used in two cooling towers and as boiler feed water. To meet the very strict water quality standards required by Marafiq and minimize the impact on the environment, Veolia Water, through its subsidiary Sidem, has designed a plant to limit the risk of plant failure and extend its lifespan, while at the same time reducing the site's energy requirements and costs. After an initial treatment phase involving dissolved air flotation, to capture the suspended particles in the water, and UF, the water will then be desalinated by RO membranes before being remineralized. system for the Fujairah 1 Independent Water and Power Plant (IWPP) in the UAE to help ensure an uninterrupted potable water supply from the desalination plant to Abu Dhabi emirate and the east coast. The source seawater in the Gulf of Oman is subject to harmful aquatic algal blooms, known as red tides, that contain large concentrations of potentially toxic microorganisms. Xylem's Leopold® ClariDAF® system is more than 95% effective clean, fresh drinking water. Fujairah 1 IWPP, which is owned by Emirates Sembcorp Water & Power Company, a joint venture between Abu Dhabi National Energy Company, Sembcorp Industries and Abu Dhabi Water & Electricity Authority. The new system will have a capacity of 136,000 m3/d (reverse osmosis output) to accommodate an anticipated 15% increase in the population by 2016. BEL supplies Al Jubail expansion Around 1,600 reverse-osmosis pressure vessels are to be supplied by BEL Composite Iberica SL for the SWRO-4 expansion of the existing Al Jubail desalination plant in Saudi Arabia. The consortium led by Acciona Agua ordered the pressure vessels for the 100,000 m3/d project which is being built in Jubail Industrial City for Marafiq Power & Water Utility Company for Jubail and Yanbu. The pressure vessels, supplied from BEL's production facility in Murcia, Spain, are equipped with high-grade steel side-ports in a state-of-the-art multiport arrangement. ERI pressureXylem provides DAF for Fujairah 1 exchangers for in removing these microorganisms prior Xylem Inc has won a contract to provide a Carlsbad … to desalination ensuring the production of dissolved air flotation (DAF) pretreatment Fourth IDE Progreen sale goes to Australia IDE Technologies is to install its Progreen™ desalination system – the fourth installation worldwide – at a five-star island resort on Australia's Great Barrier Reef. The company announced on 6 August 2013 that Mulpha Australia, the owner of Hayman Island resort in Queensland had selected IDE to provide high-quality desalinated water to the island resort. Mulpha selected Progreen based on its modular, chemical-free concept and compact size and low energy consumption requirements. "As a result of its 'plug and play' abilities, the plant should be up and running in a relatively short time," said Mulpha Australia's Greg Timar. "An important aspect in the decision to award IDE the new plant was the ongoing operation and maintenance support to be provided to Hayman from the IDE Australian office." IDE Technologies CEO Avshalom Felber said: "Partnering with Mulpha is particularly pleasing as it continues the relationship established by IDE and Hayman in 1985 in the supply of the island's current thermal desalination plant, which is to be replaced." Under this new agreement, IDE will operate and maintain the desalination plant for 10 years | 8 | Desalination & Water Reuse | August-September 2013 IDE Technologies has selected pressureexchangers from Energy Recovery Inc (ERI) for the 189,000 m3/d Carlsbad seawater desalination plant in California, USA. ERI will provide 144 of its PX® Pressure Exchanger Q300 units to the reverseosmosis plant. The units are expected to ship by the end of the year. The PX technology is estimated to save California's first large-scale plant an estimated 116 million kWh of energy per year, the equivalent of US$ 12 million. … and for Valdelentisco refit Spain's Cadagua has chosen PX® energyrecovery technology for its refit contract for the Valdelentisco desalination plant in Murcia, Spain. Energy Recovery Inc is supplying the units for phase 1 of the project which involves retrofitting two reverse-osmosis trains in the 140,000 m3/d plant owned by Acuamed. In Spain, ERI technology has been chosen in a majority of 2012-13 retrofit operations and has saved customers 1.5 billion kWh and more than US$ 158 million per year.
