Pall Corp. announced that it was awarded a $15.8 million contract by Minneapolis Water Works to provide a Pall Aria membrane water treatment system for the city’s Fridley membrane filtration plant. Fridley will be the largest pressurized ultrafiltration (UF) plant in North America, with a capacity of 95 mgd. The Pall Aria system will be used to provide a reliable supply of safe drinking water to businesses and residents of the city of Minneapolis and surrounding areas.
Minneapolis draws its drinking water from the Mississippi River. This poses many challenges due to rapid changes in water quality and variations in turbidity, temperature and contamination. To overcome them, the city turned to membrane ultrafiltration, one of the most advanced technologies available to cost-effectively provide the highest quality drinking water. Pall won the contract after Minneapolis Water Works completed extensive performance testing of competing ultrafiltration membrane pilot scale systems in June. The pilot tests demonstrated that the Pall Aria UF membrane system successfully and efficiently removed microbial pathogens (viruses, bacteria and protozoan cysts) and particulate contaminants from the source water.
“The city of Minneapolis is on the leading edge when it comes to implementing state-of-the-art water treatment technologies and upgrading its facilities to meet current and anticipated future regulations,” said Jeff Seibert, president, Pall Water Processing. “While Fridley will be the largest pressurized ultrafiltration membrane plant in North America, the Pall Aria system is available in packaged or custom configurations to provide potable water for communities of any size.”
CH2M HILL, a global full-service engineering, construction and operations firm, will design, manage construction and commission the Fridley plant, which is expected to be fully operational in 2011.
