Advanced Pall Filtration Picked for Municipal DrinkingWater.

PORT WASHINGTON, N.Y.--(BUSINESS WIRE)--Jan. 4, 1999--Pall Corporation applies 52 years of filtration expertise to meet stringent new requirements for safe drinking water.

The San Patricio Municipal Water District has selected the Pall Membrane Microfiltration System for its new 5.2 million

Membrane filtration is the best method for effectively eliminating pathogens in water. Pall membrane systems produce drinking water that exceeds the standards set by the Environmental Protection Agency's Surface Water Treatment Rule. The Pall membrane removes both bacteria and parasites, including Giardia Lamblia and Cryptosporidium to levels far below those required by the EPA. Cryptosporidium and Giardia are protozoan parasites that affect the gastrointestinal tracts of humans. Nausea and diarrhea are the usual symptoms of cryptosporidiosis. In 1993 in the worst outbreak in modern U.S. history, 403,000 people became sick and 100 people died in Milwaukee, Wisconsin from this waterborne parasite. Outbreaks continue to be reported throughout the world.

Cryptosporidium and Giardia are found in nearly 99% of surface waters. These parasites are effectively removed with Pall's advanced Membrane Microfiltration System. Chlorine, one of the most common methods by which municipalities purify their water systems, has proven ineffective against Cryptosporidium. Its use was recently limited by the amended Safe Drinking Water Act since it combines with natural organic systems in water to form potentially harmful byproducts.

Eric Krasnoff, Chairman and Chief Executive Officer of Pall Corporation, said, "The availability of safe drinking water is a major concern throughout the world. As the quality of water supplies becomes more uncertain, municipalities are increasingly seeking advanced solutions. Pall's Membrane Microfiltration Systems are able to meet the public need for the safest water supply possible. Pall is proud to work in partnership with San Patricio in this effort."

Senior Project Engineer Jim Vickers of Malcolm Pirnie, consulting engineer to the San Patricio Municipal Water District noted, "For this site, results of the pilot study and bid evaluation indicated that the Pall Microfiltration System was the most economical alternative. We also believe that it is important to exceed current as well as proposed regulatory standards, and the use of Microfiltration will allow the district to provide the highest level of filtration possible within the constraints of the project."
