business November-December 2015 | Desalination & Water Reuse | 7 | Mitsubishi joins with PUB to test water recycling technology Singapore's national water agency, PUB, has contracted Japan's Mitsubishi Corporation to build a demonstration-scale plant to test energy saving technologies that may be deployed at the proposed Tuas Water Reclamation Plant (WRP). The 12,500 m³/d, fully automated demonstration plant will assess new technologies which, along with established technologies, PUB anticipates will enable the planned Tuas facility to produce less sludge and produce more biogas for power generation while consuming less energy than conventional plants. The demonstration plant, sited within PUB's Ulu Pandan WRP, will also be a training facility for operators and serve to validate parameters for optimum used water treatment. Mitsubishi said that with this project, it will continue to work to advance its water treatment and recycling technology to grow its water treatment business globally. The tender for the plant was awarded to Mitsubishi Corporation last month. Mitsubishi Heavy Industries Asia Pacific (MHI) has been contracted by Mitsubishi Corporation to construct the plant. The plant is scheduled for completion in February 2017. The Tuas WRP will be the key component of the second phase of a giant network for the collection, treatment, disposal and reclamation of used water – the Deep Tunnel Sewerage System. The second phase will extend the system to the west of Singapore island. MHI and PUB signed a memorandum of understanding in 2012 to collaborate on a test project at Jurong WRP to treat industrial used water. CoNtRaCt&teNDeRNeWs RWL consortium wins Baja California desalination deal Mid market water treatment firm, RWL Water, in a consortium with Mexican partners, Libra Ingenieros and RJ Ingenieria, has won a contract to build a 22,000-m³/d seawater desalination plant in San Quintín, Baja California. The purpose of the plant – located 250 km from the US Mexico border – is to preserve the local groundwater resources by covering the demand for 100,000 Baja California residents. It will seek also to boost region's the economic development. The Secretariat of Infrastructure and Urban Development for the state of Baja California and the State Water Commission of Baja California (CEA), issued an invitation to tender for the project in June this year following an unsolicited proposal prepared and submitted by Libra Ingenieros and RJ Ingenieria under new PPP legislation. CEA will purchase the output of the plan under the 30-year build, own operate contract. The consortium will fund the project with a mix of equity investment and limited recourse finance. The desalination plant will be built by RWL Water based on its technology, know-how and project management. RWL Water president and chief executive officer, Henry Charrabé, said: "This confirms our business concept of providing complete high-tech water solutions with turnkey contracting and investment into our clients' water infrastructure." The plant is expected to start operation in autumn 2017. Aquatech installs Emirates desalination plant Water and wastewater technology company, Aquatech, has installed a 60 Ml/d seawater reverse osmosis-based desalination plant at Ghalilah, in Ras Al Khaimah, the northernmost of the United Arab Emirates (UAE). UAE is seeking to reduce its dependence on groundwater by 90% over the next two years. The Federal Electricity and Water Authority (FEWA) awarded Aquatech the engineering-procurement- construction contract to build the plant. Aquatech will provide operations supervision and support to FEWA. The US$ 82 million plant was commissioned in March 2015 and supplies drinking water for the Emirate of Ras Al Khaimah. It is FEWA's largest desalination plant to date. "This facility is a pioneer plant in terms of the latest technologies that were used, which enables FEWA to save millions of Dirhams in term of reducing power consumption," said director general of FEWA, His Excellency Mohammed Mohammed Saleh. Aquatech provided the core reverse osmosis plant, the seawater intake, ultrafiltration, post-treatment, and a sophisticated system for performance enhancement and data monitoring. The company supplied dissolved air flotation technology to protect the plant from seasonal red tides of harmful algal blooms.
