ESNA - Energy Saving Nanofiltration Membrane Element

High performance energy savings ESNA nanofiltration membrane elements are ideal for softening applications and the removal of pesticides, 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. At the Boca Raton plant THM formation potential was reduced from 0.60 mg/Lto less than 0.020 mg/L,well below the 0.042 mg/L limit.

ESNA elements are available from Hydranautics in both 4-inch and 8-inch diameters by 40-inch long spiral wound configurations for many applications. Smaller diameter elements are also available from Hydranautics' licensed manufacturer Oltremare, located in Fano, Italy.

Our ESNA elements can be used as either a stand alone product or part of our Integrated Membrane Solution ® (IMS) which combines a range of RO, NF, UF and MF membrane technologies to achieve the most comprehensive, effective, low-cost results in the industry.
