PROJECTS August-September 2015 | Desalination & Water Reuse | 21 | LOw-EnERgy dESaLinaTiOn TRiaLS dELayEd Trials of four new energy efficient desalination systems from leading water technology players that could "revolutionise the industry" have been delayed from their summer 2015 start with October forecast as the date when all will be in pilot operation. The trials, off the coast of Ghantoot, Abu Dhabi, are being run by Abu Dhabi energy company, Masdar. It invited the four international water technology firms to test techniques that could reduce the energy intensity of desalination and form the basis for a large, renewably powered water purification facility. When the trials were announced last autumn, associate director at Masdar, Mohammed El Ramahi, said the trials could "revolutionise the industry". Senior manager at Masdar Special Projects, Alexander Ritschel, was reported recently in a regional newspaper as saying that it will be October 2015 before all four prototypes are fully functioning. Veolia's 300 m³/d plant is expected to be the first to start operation with an August start date. It will aim to improve on established technologies by integrating filtration and dissolved air flotation pretreatment with reverse osmosis. Suez Environnement, is about halfway through and is building a second plant with a capacity of 100 m³/d with a start date anticipated in September. Califonia-based Trevi Systems plans to build a 50 m³/d forward osmosis-based plant while Spain's Abengoa is building a 1,000 m³/d plant – the largest of the four facilities. Trevi expects to have its plant in full operation in October. The facilities' energy consumption will be monitored hourly throughout the 18 months of operation and the quality of the potable water will also be monitored. RaS PROJECT winS dESaLinaTiOn PLanT Of ThE yEaR awaRd The Ras Al Khair project in Saudi Arabia, has won the Desalination Plant of the Year award at the 2015 Global Water Awards. The plant is owned by Saudi's state-owned Saline Water Conversion Corporation (SWCC) which had appointed Pöyry as engineer responsible for project management, design review and site supervision. The plant has been expanded recently to add 240 Ml/d to its output as a part of a SR 300 billion (US$ 80 billion) investment plan running for the next ten years. The purpose of the investment is to increase SWCC's production of desalinated water by more than 44% to 5,200 Ml/d in less than two years and on to 8,500 Ml/d by 2025. The Ras Al Khair plant - the largest combined power and desalination facility in the world – includes multi stage flash and seawater reverse osmosis desalination and deploys the largest membrane plant in the Gulf of Oman. It also uses dissolved air flotation pre-treatment in converting more than 1 billion litres of seawater into potable water each day. Maximum Recovery.
