Pentair Develops Nanofiltration Technology To Address Water Needs Around The World

"At Pentair, we have made significant investments in developing new technologies that help meet the growing demand for clean water around the world," said Phil Rolchigo, vice president of technology. "Our innovation in hollow fiber nanofiltration is its ability to treat the complex mixture of organic compounds found in fresh water. It uniquely addresses drinking water filtration challenges, and is also highly versatile in wastewater treatment across industries."

For drinking water treatment, nanofiltration allows for selective separation, eliminating certain contaminants such as bacteria, humic acids and total organic carbons (TOC) while maintaining desired levels of healthy minerals or nutrients, such as calcium and magnesium. The technology also can be utilized for treating wastewater in numerous applications including food and beverage, energy and industrial markets. In both applications, it can be a more energy- and cost-efficient process than reverse osmosis and more effective at removing contaminants than ultrafiltration processes.

Pentair s latest nanofiltration technology offering, the X-Flow Color Removal Package (CRP), is launching this summer. The core component is the hollow fiber membrane, which delivers many advantages compared to conventional technologies including a 99.999 percent reduction of bacteria and viruses, a single-step pre-treatment process and a simplified treatment operation system. The company first introduced its hollow fiber nanofiltration platform in November 2011 at Aquatech, the world s leading trade exhibition for process, drinking and waste water, where it won the award for "best innovation not to market yet." Pentair s first nanofiltration product launched in early 2012.
