QUA UF modules get NSF/ANSI certificate
Pennsylvania-based membrane developer QUA has been awarded NSF/ANSI 61 certification by NSF International for the manufacture of its Q-SEP® range of hollow-fiber ultrafiltration (UF) modules.NSF/ANSI Standard 61 certification is for Drinking Water System Components - Health Effects, the recognized health effects standard in the USA for all devices, components and materials that contact drinking water. Recognized by regulatory agencies at the local, state, federal and international level, the NSF certification means that the product complies with all standard requirements.
Q-SEP UF modules are used for such applications as pretreatment to reverse osmosis (RO) desalination systems (brackish and seawater applications), purification of surface and well water for potable applications, filtration of industrial water, and wastewater recycle and reuse.
The modules contain membranes manufactured with QUA's patented "Cloud Point Precipitation" method. This innovative process ensures a high pore density along the length of the fiber and uniform pore size distribution in the membrane.
Q-SEP modules deliver superior performance characteristics and product water quality that surpass the quality from conventional UF modules, with low silt density index (SDI) and excellent rejection of bacteria and viruses.
"QUA is dedicated to manufacturing products of superior quality and operating our facilities according to the highest standards. We are very pleased to have been awarded this prestigious certification by NSF, which is recognized internationally for its commitment to protecting and improving human health on a global scale," said V J Nathan, technical director, QUA Group LLC.
