aqualia awarded Abu Dhabi water management contract
MARKET PROSPECTS which is located in south-eastern Turkey near the city of Urfa. The treatment scheme consists of mechanical and biological treatment using the activated sludge process with subsequent anaerobic sludge treatment and dewatering. During anaerobic stabilisation, the sludge will be fermented in bioreactors and the flammable gas thus released will then flow into a cogeneration plant, while the waste heat will be employed for the heating of the bioreactors. This means that the plant can produce a sizable percentage of its energy requirements itself, helping reduce operating costs and saving energy.
aqualia awarded Abu Dhabi water management contract
A
consortium led by Spain’s aqualia and local company Mace has been awarded a seven-year E76.3 million contract to manage a sewage and water treatment system in Abu Dhabi. The contract, which was awarded by Abu Dhabi Sewerage Services Co, includes the operation and maintenance of more than 2400 km of sewers, 68 wastewater-pumping stations and 19 wastewater treatment plants in the city of Al Ain and the surrounding areas. aqualia, the water division of FCC, has been operating in Saudi Arabia since 2011, where it is implementing a project to search for and repair leaks in Riyadh’s water network in order to increase the network’s efficiency.
Ecologix launches water treatment solution for hydraulic fracturing

essentially all suspended solids, fats, oils and greases from wastewater, produced water and frac water. The system also features integrated PLC controls, dual whitewater pumps, dual sludge pumps, a mobile platform and a skimmer assembly. Ecologix has designed the ITS to allow the water to be re-used for future drilling. “With increasing environmental scrutiny associated with hydro-fracking, we designed the system to treat the water so that it could be used or industrial recycle and re-use, rather than discharged into ground wells,” said Eli Gruber, CEO of Ecologix. “This treatment method is both environmentallysustainable and affordable, which is just what the industry needs to continue fracking operations in the future.” “Efficient and affordable water treatment is one of the biggest operational challenges with hydro-fracking, and there is a need for new treatment methods that are environmentally compliant and economically viable,” said Gruber. “The mobility and treatment capacity of this system is an industrybreakthrough that will change the way frac water is treated.”
MINING
Trevali selects Veolia Water for Canadian mine effluent project
V
eolia Water Solutions & Technologies Canada is to design and supply a 1000 m³/day effluent treatment plant for Trevali Mining Corp’s Halfmile Zinc-Lead-SilverCopper Mine in New Brunswick. The fast-track design-build project includes the entire treatment plant as well as the construction of the building. The treatment plant will provide precipitation, decantation, filtration and pH correction. The plant incorporates metals precipitation using ACTIFLO TURBO, a high-rate, small footprint clarification process. After clarification, the water undergoes sand filtration to remove any remaining solids, followed by pH correction. The new zinc-lead-silver-copper mine is situated 60 km south of Bathurst and started production in January 2012.
POWER GENERATION
Scottish Water announces £20mn hydropower scheme
S
cottish Water will undertake a £20 million hydropower scheme that will use the flow in large water supply pipes to generate electricity and protect water treatment plants from power failures. The hydropower scheme could reduce the power costs for water treatment by 10%, playing a key part in keeping Scottish Water’s operating expenditure down. Water and wastewater treatment is energy intensive and complex, with the majority of Scottish Water’s energy used in pumping water. Even with the generally high raw water quality in Scotland, a lot of energy is required to treat water to meet the standards set out by the Drinking Water Quality Regulator and the Scottish Environment Protection Agency (SEPA). More than 30 sites have been identified that could – using techniques most commonly seen in hydropower schemes – power the water treatment process in areas such as rural Lanarkshire, the Borders, Stirlingshire, Angus and Fife. The hydropower schemes will make use of existing Scottish Water buildings and also see the construction of some small buildings and electricity infrastructure to transfer the power from the point of generation back to the water treatment works. Some of the electricity infrastructure will be offgrid, so any major power loss by the power companies would not affect the supply of water to customers.
