| Black & Veatch wins Global Water Award Black & Veatch, a global engineering, consulting and construction company, won the prestigious Water Project of the Year award at the 2006 Global Water Awards for the Columbia Heights Membrane Ultrafiltration Plant, located near Minneapolis, Minn. With a current capacity of 70 million-gallons-per-day (264, 979 cubic-meters-per-day) and an ultimate capacity of 78 mgd (295, 262 m 3/day), the Columbia Heights membrane filtration plant is the largest facility of its kind in the Western Hemisphere and represents the leading edge in membrane filtration technology for potable water. Source water drawn directly from the Mississippi River receives numerous discharges in the watershed including agricultural runoff, power plant cooling water and effluent from sewage treatment plants. Columbia Height's ultrafiltration fiber pores are 10 times smaller than conventional microfiltration pores, and they provide a physical barrier against developing risks to water quality including viruses and the smallest pathogens. The fiber pores have the capability to remove viruses 3 percent the size of Cryptosporidium. write your comments about the article :: © 2006 Construction News :: home page |
