Case Histories Presented at WEFTEC Conference Demonstrate Technology is a Low Cost Alternative for Water Reuse

Water reuse using membrane technology is fast becoming a practical and reliable means to conserve limited water supplies, especially in drought stricken areas. Pall Corp. membrane technology, which has found wide acceptance around the world in transforming wastewater into a reusable resource for general industrial use and irrigation, was the subject of a presentation at the annual Water Environment Federation Conference and Exposition (WEFTEC) on Monday. The presentation "Membranes for Industrial Water Reuse" focused on how water districts and industrial plants in three states — California, Arizona and Florida — saved precious water supplies and also costs by installing Pall AriaSM membrane systems on secondary treated wastewater effluents.

"These facilities found that water reuse by membrane filtration is a cost effective alternative to producing high quality water for manufacturing, power generation, irrigation and the protection of watersheds that supply drinking water from treated wastewater discharges. Cost savings of up to 50 percent were reported by plants using Pall membrane filters for water reuse," said James Schaefer, PE., Vice President of Pall Water Processing.

Pall’s microfiltration and ultrafiltration membrane systems protect against the passage of pathogens, such as Cryptosporidium and Giardia lamblia, viruses, bacteria and other contaminants. Cryptosporidium, a chlorine resistant waterborne parasite regulated by the U.S. Environmental Protection Agency (EPA), is present in much of the world’s water supply. AriaSM membrane systems reliably meet or exceed the EPA’s standards for Cryptosporidium removal and drinking water quality at the lowest cost of ownership.

systems are skid mounted, modular in design and fully automated for easy operation. Their flexibility makes them practical and affordable for both large and small water reuse installations. Systems that process as little as .07 million gallons per day (mgd) to those processing over 45 mgd are available to industry and municipal water reuse plants.
