Pall Corporations microfiltration technologies have been certified under NSF and the U.S. EPA Drinking Water Systems Center as an effective removal technology for arsenic under the new EPA regulation of 10 ppb in drinking water. The Pall systems are the first microfiltration system to be certified under the DWSC for arsenic removal. Unlike RO or other arsenic removal options, microfiltration offers a less costly long term solution. There is no major upfront capital investment, no high operating costs and no need for frequent regeneration and purchase of media. The Pall Aria System works by the addition of an iron-based coagulant, such as ferric chloride, to the water. The contaminating arsenic is adsorbed onto positively charged ferric hydroxide particles.
