荷兰鹿特丹位列全球可持续水环境城市榜首 美国南加州水管理区将投资1.1亿美元建设水回用设施 威立雅将负责爱尔兰最大污水厂的污泥处理系统升级改造 美国公司研发工业水超滤+反渗透组合工艺 Rotterdam Tops Global Sustainable Cities Water Index 荷兰鹿特丹位列全球可持续水环境城市榜首 The Dutch port city, Rotterdam, has been ranked the top city for water sustainability, according to the inaugural Sustainable Cities Water Index from engineering and consulting company, Arcadis. Two northern European cities, Copenhagen and Amsterdam, took second and third place respectively. Conducted by Arcadis, in partnership with the Centre for Economics and Business Research, the index explores the three aspects that make up robust (resiliency), effective (efficiency) and healthy (quality) waterscapes to develop an indicative ranking of 50 leading cities. “Great cities are defined and illuminated by the water that surrounds them or flows through them, and they will continue to be over the coming decades,” said John Batten, Arcadis Global Director of Cities and Water. “This report highlights the areas of opportunity for cities,to inform decision-making around how they use and manage water, hopefully making them more sustainable economically, environmentally and for the benefit of their people.” The report finds that most cities need greater investment when it comes to their ability to withstand natural disasters and drinking water shortages, with climate adaptation and resiliency being the most pressing issue for future city leaders. Meanwhile, the area in which cities tend to perform best is water quality. Despite some locations having areas of challenge protecting their citizens there is little variation between most of the cities in the top half of the index. The index found a lack of urban green space impacts the resiliency of many cities in the Middle East and Asia and that US cities are among the most susceptible in the developed world to higher flood risks due to natural disasters. It was also noted that world cities like New York, London and Hong Kong that have a greater water vulnerability were not featured in the overall top ten. WRD Gains Approvals to Construct $110m Water Recycling Facility美国南加州水管理区将投资1.1亿美元建设水回用设施The Water Replenishment District of Southern California (WRD) in the US has secured approvals to proceed with its plans to construct a $110m water recycling facility on a 5.2-acre parcel in the northeast part ofthe city adjacent to the San Gabriel River channel. Following the approval by Pico Rivera city officials,construction of the, 25,000ft² plant is expected to begin later this year. The Pico Rivera Planning Commission voted 5-0 to award a conditional use permit (CUP) for the Groundwater Reliability Improvement Project (GRIP). The project outlined various steps to be taken by the water agency to ensure its project reduces impacts to neighbours both during and after construction. WRD director Albert Robles said: 'After nearly a decade of planning, the Groundwater Reliability Improvement Project is approved for construction, marking a major leap forward toward complete and permanent local sustainability of the groundwater basins that provide half the water supply to over four million people.' The GRIP facility is planned to be constructed on property at 4320 San Gabriel River Parkway, the former site of a trash-hauling business. It will produce enough water to offset the existing demand for imported water used for groundwater replenishment and will also include a water education space and drought-tolerant demonstration gardens. WRD manages the groundwater for the Central and West Coast Basins, which supplies roughly 50% of the water demand for a 420 square mile region which with 43 cities in southern Los Angeles County. GRIP facility will purify recycled and treated wastewater obtained daily from the nearby San Jose Creek Water Reclamation Plant. Later on, WRD will deliver the water to groundwater percolation basins in Pico Rivera and enter the aquifer system. Veolia to Upgrade Ireland Sludge Facility to Cope with Municipal and Industrial Growth 威立雅将负责爱尔兰最大水厂的污泥处理系统升级改造Irish Water, working in partnership with Dublin City Council, today announced it has signed a €8 million contract with Veolia to upgrade the Drinking Water Sludge Treatment Facility at Ballymore Eustace Water Treatment Plant. Ballymore Eustace is the largest water treatment plant in Ireland, supplying approximately one million customers in Dublin City, South County Dublin, Dun Laoghaire, parts of Wicklow and Kildare. The contract has been signed with Veolia and work is expected to commence in September 2016 and take 15 months to complete. This contract completes an overall €15 million investment that Irish Water is carrying out at the plant to upgrade the Sludge Treatment Infrastructure at the Water Treatment Plant. This investment improves the resilience of Ballymore Eustace Water Treatment Plant which is critical for the water supply to the Greater Dublin Region. Under the contract, Veolia will be responsible for the design, construction, commissioning, testing, and maintenance of the sludge treatment plant to assist in ensuring the facility can safely supply the 400,000 m3/day processing capacity of the works. During the design and construction phase, the company will deliver a new sludge de-watering system, thermal sludge dryer, and sludge storage and handling facilities. Refurbishment works will also upgrade grit removal, filtration, thickening and ancillary equipment. Greater automation and monitoring capabilities for the new installations will be gained from a new site SCADA (Supervisory Control and Data Acquisition) system. Following the installation phase of the contract Veolia will be responsible for commissioning, testing, and maintenance of the sludgetreatment plant. Niall Gleeson, managing director at Veolia Ireland, said: “By working with Irish Water to upgrade this critical water treatment infrastructure we will be able to assist in ensuring the greater Dublin area’s water needs are met now and into the future.” UF/RO Membrance Combo Trailer Launched for Industrial Water 美国公司研发工业水超滤+反渗透组合工艺 Following two years of R&D, MPW Industrial Services has introduced a combination ultrafiltration-reverse osmosis mobile trailer. The technology has been designed for industrial clients purifying surface water with production requirements of 150 to 300 gallons per minute but can also treat water from ground and municipal sources. Launched at the American Electric Power Boiler Reliability Optimization Forum, the integration of the UF and RO modules requires less space than separate systems, when companies are conducting maintenance or repairing onsite water purification systems. The ultrafiltration portion of the system, with two racks and an on-board filtrate tank, removes total suspended solids, organics, iron, manganese and other contaminants. Standard instruments include feed and filtrate turbidity, flow rate, pressure sensors, pH, conductivity and water temperature. A programmable logic control system monitors and adjusts conditions to maintain consistent and reliable operations. Remote monitoring and troubleshooting are standard features. Justin Pierce, director of engineering for MPW's industrial water division, said: “Transportation costs are cut in half because we only need to make one trip to the customer's plant site instead of two. In addition, customers only need one power feed. Moreover, less plumbing and electrical wiring is required because we integrate the two systems at our plant. That saves a considerable amount of time during the setup process.' |
