High performance energy saving ESNA nanofiltration membrane elements are ideal for softening applications and the removal of pesticides, pathogens, bacteria or viruses. They provide 50% - 90% salt rejection with ultra-low-pressure operations, increased energy savings, and significantly lower installation and operating costs. They can effectively remove organics which can form disinfection by-products in municipal water distribution lines.

Hydranautics also offers Integrated Membrane Solutions (IMS) combining a range of RO, NF, UF and MF membrane technologies to achieve the most comprehensive, effective, low-cost solutions for the industry.
