New 75- and 100-gpd elements help remove contaminants and impurities in household water systems
Dow Water & Process Solutions, a business unit of the Dow Chemical Co., launched Filmtec reverse osmosis (RO) 75- and 100-gal-per-day (gpd) home drinking water membranes at the WQA Aquatech USA 2013 conference and exhibition.
The RO membranes are the company's latest innovation to facilitate potable water that tastes better, smells better and has fewer impurities to help bring clean drinking water to homes in water-stressed areas.
The new elements help remove contaminants that can lead to health risks, and reduce impurities such as calcium, magnesium and iron. With a stabilized salt rejection rate of 99% at 75 gpd and 98% at 100 gpd, in standard sizes (1812 configuration), Dow Filmtec BW-60-1812-75 and TW30-1812-100HR home drinking water elements offer premium water faster. The new 75-gpd membrane uses new Dow membrane chemistries that have been customized to maximize element performance. The elements offer a balance of flow and high rejection, producing more water with 20% higher flow rates at standard test conditions.
These residential elements feature longer lifetimes that can potentially reduce operating costs for OEMs and brand owners, as well as NSF Intl. safety certification and the ability for NSF data transfer to help reduce certification costs. Fully automated manufacturing facilitates consistent, high-quality elements, while dry shipping offers convenient handling and longer shelf life.
The elements are manufactured in an ISO-certified facility in the U.St. They are NSF/ANSI 58 listed for material safety requirements, which means their safety and performance have been evaluated by NSF, the leading global provider of public health and safety risk management solutions.
