USFilter and Paques Sign License Agreement for Filtration Technology

USFilter and Paques bv of the Netherlands signed an exclusive license agreement for Paques' sand filtration technology. USFilter will design and supply Paques' ASTRASAND® Continuous Backwash Filter for applications in the United States and Canada.

The ASTRASAND® filter was developed for physical-chemical and/or biological treatment of different types of water, such as process, waste, surface, cooling and groundwater. Working as a continuous process, the filter bed is cleaned during the filtration operation. Thus, interruptions are eliminated.

The filtration technology can be used for many types of industrial and municipal applications: biological nitrification/denitrification and polishing of municipal and industrial wastewater, filtration of flocculated contaminants in surface water, washwater treatment in fresh and process water production, biological sidestream filtration of cooling water, and biofiltration for BOD and heavy metal removal.

"The ASTRASAND® technology supplements our conventional filtration offering and allows us to provide a broader line of filtration technology to our customers," said Frank Firsching, president of USFilter Water and Wastewater Systems Group.

Under the license agreement, Paques will share the technology with USFilter. A team of water and wastewater specialists, working in cooperation with Paques experts in Europe, will design and supply treatment plants throughout the U.S. and Canada.
