BUSINESS February-March 2016 | Desalination & Water Reuse | 11 | Evoqua municipal wins top US$ 20 million Water treatment firm, Evoqua, has won contracts worth more than US$ 20 million supplying its Memcor microfiltration and ultrafiltration product line to six US and Canadian municipalities. The deals were for filtration, water reuse, drinking water treatment, and reverse-osmosis pre-treatment applications. The contracts are with: The Mohawks of the Bay of Quinte, Canada; Genesee, Colorado; Port Townsend, Washington; Terminal Island, California; Morgantown, West Virginia and County of Hawaii. At the Bay of Quinte, Evoqua will provide Singapore desalination plant upgrade will use ceramic membranes An upgrade planned for later this year at Singapore's Choa Chu Kang Waterworks will use ceramic membranes in a first for the country. Ceramic membrane technology is, according to the country's national water agency, PUB, expected to increase the plant's operating efficiency and reliability. PUB also forecasts that its life-cycle cost will be lower than those for conventional membrane systems. PUB will collaborate with PWN Technologies (PWNT) to deploy PWNT's CeraMac ceramic membranes to upgrade part of the water treatment system at Choa Chu Kang. UGL (Singapore) will design and build the plant, with the membrane systems from PWNT and ceramic membranes supplied by Japanese ceramic membrane specialist Metawater. the process solution for a new water plant including two Memcor submerged packaged XS48 units along with pre-treatment to the membrane system which includes Envirex Products' Folded Flow Dissolved Aeration Floatation units and a packaged clarification system. The new plant will treat 16.1 l/sec of raw water from the Bay of Quinte. The Port Townsend deal is for a Memcor CP 12 Ml/d drinking water system deploying a gravity head-driven set up to reduce energy use and operating costs. The Terminal Island project is the third phase in an expansion of a major water reclamation facility serving Los Angeles. A MemPulse membrane bioreactor system under construction at Morgantown will supply initially up to 52 Ml/d with an average output of 36 Ml/d. It will replace a 32 Ml/d rotating biological contactor that has reached the end of its useful life. The Department of Water Supply in Hawaii is building a Memcor CS system as part of its Waimea water treatment plant upgrade. Bodell Construction won the contract to upgrade the 60-year-old Waimea surface water treatment plant with submerged membranes to up the capacity of the drinking water plant to 16 Ml/d. The CeraMac plant's capacity will be 160 Ml/d and it will be operational in 2018, said PUB. Upon completion, the plant will be one of the largest ceramic membrane plants for drinking water treatment in the world. Tests at PWNT's CeraMac demonstration plant were carried out from September 2011 to validate the efficiency and reliability of its ceramic membranes in water treatment. PUB's chief technology officer, Harry Seah, said: "PUB is always on the lookout for more innovative and cost-effective ways of treating and producing water. We have been studying and testing the merits of ceramic membrane technology for a few years now, and we are satisfied with the results. Both polymeric and ceramic membranes can now be considered in our other waterworks when they are due for upgrading." Black & Veatch picks up key roles in Hong Kong and Singapore Consultant, Black & Veatch, will perform key roles in two planned desalination projects in Hong Kong and Singapore. Both plants, according to the company, will set new design and energy-use benchmarks for water treatment plants. "We have partnered with Singapore and Hong Kong water utilities on some of the world's most innovative water engineering solutions," said president of Black & Veatch's water business, Cindy Wallis-Lage. "Both desalination projects are further examples of how these leading Asian cities are applying Oman names preferred bidders for Sohar and Barka projects The Oman Power and Water Procurement company has named its preferred bidders for two major water desalination projects planned at Sohar and Barka on the sultanate's Batinah coast. The government-owned procurer has chosen a consortium led by Spanish water services company, Valoriza Agua to develop an independent water project (IWP) at Sohar and another consortium led by Japanese conglomerate, Itochu Corporation, to develop the Barka IWP according to local press. Negotiations will follow to settle separate licenses for the development, design, construction, ownership, financing, operation and maintenance of the two projects. Madrid-based Valoriza Agua joined with Oman's Brunei Investment Company and Sogex Oman to bid for the two projects. Itochu Corporation linked with Degremont, International Power and W J Towell. They were selected from seven consortiums that submitted offers in August. Failed bids came from five other consortiums – led by Abengoa, GS Inima, Hyflux, JGC and Veolia. Together, the two projects make up the single largest procurement of desalination capacity in the Oman. Total investment in the ventures is US$ 550 million. The two water-only schemes will be powered from the grid. The 281,000 m³/d Barka IWP will be the larger of the two schemes with the Sohar IWP, coming in at 250,000 m³/d of desalination capacity. progressive thinking to secure future water supplies for their people," she added. In Hong Kong, the government's water supplies department has appointed Black & Veatch as the owner's engineer to develop the first stage of the protectorate's Tseung Kwan O desalination plant. Its initial capacity will be 180 Ml/d which will meet about 5% of Hong Kong's water demand. Black & Veatch recently completed the plant's feasibility study which identified opportunities to harness green energy and reduce electricity costs.
