| 8 | Desalination & Water Reuse | May-June 2016 BUSINESS Hyflux bags Suez Canal desalination deal Singapore's Hyflux has secured a letter of intent for an engineering procurement and construction contract for a 150,000 m³/d desalination plant in Egypt's Suez Canal Economic Zone. The US$ 500 million Ain Sokhna Integrated Water and Power project will include a 457 MW gas- fired power station that will supply the desalination facility and export surplus to the grid. The deal includes a 25-year operations and maintenance contract. Chile mine desalination agreement Mining firm, White Mountain Titanium Corporation has secured a US$ 2 million debt funding agreement with private equity firm Nexo which included an exclusive development rights agreement relating to a desalination plant proposed for White Mountain's Cerro Banco mine in Chile. White Mountain has granted to Nexo Subsidiary, Nexo Water, the exclusive right to fund and develop its proposed desalination plant. Complete details of the transaction are available in an 8-K filing by White Montain. Nexo - a specialist in business development of new technologies through project acquisition and implementation opportunities - proposes to integrate the use of "proven, high- recovery desalination technologies in the design of the Cerro QUA wins electrodeionization deal QUA has won a contract to supply its fractional electrodeionization (FEDI) technology for reverse osmosis (RO) permeate polishing at a major liquified natural gas (LNG) plant on the Texas- Louisiana border. The project is the third phase of expansion to supply water to Cheniere Energy's addition of liquefaction services to its Sabine Pass LNG terminal. It will add 30% to the capacity of the water plant, taking the flow rate to 951 m³/hr, making it one of the largest electrodeionization systems installed in the world, QUA claimed. FEDI was deployed in the previous two phases. "This project is significant to us because it is our first integrated water and power project abroad and demonstrates our ability to put together an innovative solution that is recognised internationally," said executive chairman and group chief executive officer of Hyflux, Olivia Lum. The company has predicted that, subject to the signing of the contracts, the deal with have "a material financial impact" on Hyflux for the financial year ending 31 December 2016. The water is used for compressor turbines for methane, propane and ethylene; wash water for gas turbines and other utility make-up uses. These processes demand that the local utility feed-water to the terminal receives further treatment to produce high purity water with low conductivity and silica content. "This project is a great showcase for the dual voltage fractional electrodeionization process. It really demonstrates on a large scale how well the technology can perform downstream of a single pass RO system," said QUA's director of sales and marketing, Fred Wiesler Blanco desalination project". Nexo intends to increase significantly the fresh water recovery over that achievable through reverse osmosis alone. Both parties plan to create a joint venture and determine an equity split to share proceeds from future sales of water once the Cerro Blanco mine is operational. Interim chief executive officer of White Mountain, Michael Kurtanjek, said Nexo "will bring not only the necessary finance to construct the desalination plant but also the technology which could significantly increase fresh water recoveries. With NEXO assuming the funding responsibility for the water plant, this will significantly reduce the projected capex figure for the Cerro Blanco project." Evoqua lands five deals totalling US$ 20 million Five US municipalities have ordered Evoqua Water Technologies' BioMag ballasted biological treatment system for their wastewater treatment plants. According to Evoqua, the municipalities chose the BioMag system "to increase treatment capacity and help them meet stringent nutrient removal limits." The system uses fine particles of the iron ore, magnetite, that infiltrate a biological floc to make it more dense and accelerate its precipitation thereby speeding up clarification. Evoqua claims the system to be "the world's fastest and most reliable floc settling - allowing capacity expansion and performance improvement with minimal plant modifications at the lowest cost possible." The five BioMag installations contracts were in wastewater treatment plants at Front Royal, Virginia; East Norriton, Pennsylvania; Cascade and Tanneytown, Maryland; and Berkeley, West Virginia. The upgrade and 45% capacity expansion of the Front Royal wastewater treatment facility included two other Evoqua products as well as BioMag. They were the Jet Tech's Vari-cant jet aeration system, and Envirex primary and secondary clarifiers. The upgrade will enable the plant to meet enhanced nutrient removal limits for nitrogen and phosphorus without the need for tertiary treatment, Evoqua said. At East Norriton's wastewater treatment facility outside Philadelphia a new BioMag system was also accompanied by Vari-cant. The project will increase the capacity of the existing bioreactors and secondary clarifiers by nearly 70% according to Evoqua. The company said also it will enable the facility to meet future nitrogen limits cost- effectively with existing tankage. The Winebrenner Wastewater Treatment Plant in Cascade was the second facility in Washington County to be upgraded with the BioMag system to meet the new state nutrient removal standards. The county's Smithsburg Wastewater Treatment Plant was the first to use BioMag. Taneytown is upgrading its wastewater treatment facility with the BioMag system to meet the state's new nutrient removal standards while using existing tankage.
