Pentair Develops RO Systems to Remove Chromium-6 from Drinking Water

Systems also remove arsenic, lead and other undesirable substances

A report was released recently by the Environmental Working Group (EWG) with details on the detection of hexavalent chromium (chromium-6) in tap water in 31 of 35 cities tested. Chromium-6, made infamous by the movie “Erin Brockovich,” has been linked to stomach cancer and is the latest in a series of unregulated substances which have been detected in a number of treated drinking water supplies. These substances include pharmaceutical drugs and industrial chemicals, which can pass through conventional water methods.

The study suggests that those concerned can purchase a water filtration system to significantly reduce the presence of hexavalent chromium in their tap water. Pentair Residential Filtration (PRF), a division of Pentair, specializes in reverse osmosis water filtration systems for the home that are third-party certified to reduce hexavalent chromium. Chia Kung, Pentair Residential Filtration’s global product manager for membranes, leads a team devoted to producing these state of the art reverse osmosis systems.

“Pentair Residential Filtration has a long history of successfully reducing hexavalent chromium, as well as other undesirable substances, from drinking water,” said Kung. “Each of our reverse osmosis systems is designed to provide clean drinking water by separating substances such as hexavalent chromium from the incoming water source. These systems typically have four to five total stages of filtration that will separate other substances including, but not limited to, arsenic, lead and cysts.”

“I am proud to be a part of a company whose goal it is to develop technology that can improve the quality of life in our communities,” said Sam Karge, Pentair Residential Filtration vice president of global marketing. “As concerned citizens, we at Pentair are here to serve by providing high quality, water filtration solutions that residents can incorporate into their home to help alleviate the problem.”

Residents that live in areas where hexavalent chromium has been found in tap water can contact their local plumbing professional, water treatment professional or kitchen and bath dealer to purchase one of the Pentair products that specifically reduce the presence of the chemical. These products include the American Plumber WRO-3500 Reverse Osmosis system or Pentair Water RO-3000 and Pentair Water RO-3500 Reverse Osmosis systems, which are certified by NSF to reduce hexavalent chromium. Residents also can purchase the Everpure Reverse Osmosis II or Everpure Reverse Osmosis III systems as these products also reduce the substance.
