Water. desalination + reuse

BUSINESS | 12 | Desalination & Water Reuse | August-September 2014 Acciona wins Italian jobs worth US$ 4.4 million Spanish infrastructure company Acciona has won a contract to supply potable water through reverse osmosis desalination on the Italian islands of Pantelleria, Linosa and Lampedusa. Acciona's water service arm Acciona Agua through a temporary joint venture with Italian firms Sofip and Protecno, will operate an existing seawater reverse osmosis (SWRO) plant and brackish water reverse osmosis plant on Pantelleria. Combined the plants will produce a total maximum flow of potable water of 2.2 million m 3 a year. The same partners are involved in the SWRO at Lampedusa and Linosa, and the seawater treated will reach a maximum annual flow of almost 2.4 million m 3 . The total new investment in renewing the facilities is estimated at € 3.3 million (US$ 4.4 million). Acciona forecasts ten-year revenues for the project at € 54.5 million (US$ 73.7 million). Tunisia wraps up desalination feasibility study Tunisia's National Water Company, has completed a feasibility study for a 100,000 m 3 /d seawater reverse osmosis plant to be located at Zaarat, in the south east of the country. The first 50,000 m 3 /d of capacity is scheduled for a mid-2017 startup. The second 50,000 m 3 /d is planned for 2025-2026, and will be tendered separately. The African Development Bank provided US$ 2 million to finance the project's advisory phase. Tunisia's access rates to water supply and sanitation services are among the highest in the Middle East and North Africa region at close to 100% in urban areas. Saudi docks 'world's biggest' desalination kit for Yanbu Saudi Arabia has taken delivery of the second of six units to be installed at the water desalination plant in Yanbu in the third phase of the plant's expansion. e multi stage flash distillation unit weighed 3,836 tonnes and measured 135 metres in length. It will produce potable water at 94,000 m³/d. Korean ship Dongbang Jiant 3, docked with what is reportedly the world's largest water desalination equipment at Saudi Arabia's King Fahd Industrial Port. e unit was the second of four to be manufactured overseas by Doosan Heavy Industries and Construction in a US$ 1 billion deal. Another two units will be built in Saudi Arabia. e third and fourth units will be installed in November while the fih and sixth units will be installed by the first half of 2016 said head of Saline Water Conversion Corporation, Western Coast, Mohammad Al-ebaiti. Once complete the expanded Yanbu plant will produce desalinated water at a rate of 550,000 m³/d for the Madinah province. Doosan won the engineering, procurement and construction contract in December 2012. e contract included equipment design and manufacturing as well as installation and testing. Giant Saudi plant plan unveiled Saudi Arabia's Saline Water Conversion Corporation has announced plans for what would be the world's largest desalination plant. The planned site for the plant is at Rabigh on the country's west coast. The plant would be able to produce up to 600 million litres of desalinated water a day using reverse osmosis. The project was announced at Singapore International Water Week where projects, tenders and other investments worth some US$ 11.6 billion were agreed according to the event's organizers. Those deals included the opening by Beijing Enterprises Water Group of its international headquarters in Singapore. It is expected to handle about US$ 1.6 billion of investments outside China. Also at the event, authorities in Indonesia, Laos, Philippines and Vietnam announced investments in their region worth more than US$ 1.6 billion. Osmoflo wins US$ 15m wastewater reuse deal Water and wastewater firm, Osmoflo, has won a US$ 15 million contract for the design, construction and commissioning of a wastewater treatment plant in northern Western Australia to produce reclaimed water for use in irrigation. Mining giant Rio Tinto awarded the contract for the Wickham township to service its Cape Lambert Port operations from existing lagoons. The membrane-based filtration system will draw wastewater treated in line with Western Australia Department of Health Guidelines for use in irrigating open space in and around the Wickham township. Osmoflo is responsible for process design and delivery of a membrane-based ultrafiltration system including chemical dosing, chlorination and other mechanical equipment. Osmoflo has also been appointed to carry out all site installation and civil works associated with the project and commissioning. All works will be carried out in compliance with both Rio Tinto and Western Australia Water Corporation standards and will also meet regulations covering construction in cyclone-prone areas. Following commissioning and testing the plant will be handed over to the Western Australia Water Corporation. The contract will be delivered and commissioned by Osmoflo's wastewater business.
