Nanostone Water Inc’s Ceramic Ultrafiltration Module Receives NSF/ANSI Standard 61 and NSF/ANSI Standard 372 Certification

Eden Prairie, MN, Feb. 9, 2017 – Nanostone Water, Inc., manufacturer of a unique high surface area ceramic ultrafiltration membrane for municipal water/wastewater and industrial water treatment, today announced it has received NSF/ANSI Standard 61 and Standard 372 certification for its ceramic ultrafiltration (UF) membrane module. The NSF/ANSI Standard 372 was received in February of 2017, while the Standard 61 was received in August 2016. This certification, issued by Underwriters Laboratories (UL), represents Nanostone’s commitment to ensuring drinking water safety. A copy of the certification can be located on the UL manufacturer’s directory for NSF/ANSI Standard 61.

The NSF/ANSI 61/372 certified ceramic UF membrane from Nanostone Water is a revolutionary high surface area pressurized monolith style module with greatly improved permeate flow efficiency and lower energy consumption versus currently available ceramic ultrafiltration membranes. The patented design uses multiple rows of channels in flat sheet segments and incorporates multiple segments inside a pressure vessel similar to those used with polymeric hollow fiber membranes. Together with the improved energy efficiency, the high surface area and unique segmented construction drastically reduces cost of ownership, making systems using Nanostone’s ceramic UF module competitive with polymeric UF/MF systems.
