Hydranautics ESNA Series Nanofiltration Membranes
High performance energy savings ESNA (Energy Saving Nanofiltration) 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 the THM formation potential was reduced from 0.6 mg/L to less than 0.020 mg/L, well below the 0.042 mg/L limit.
Benefits
- Up to 91% nominal rejection
- Effectively removes organics
- Optimum hardness rejection
- Ultra-low pressure, energy saving, lower OPEX
- New technology for higher productivity; minimizes bio-fouling and colloidal fouling and enhancing cleanability

A New Generation of ESNA Performance
ESNA1-LF are high performance nanofiltration membranes 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.
ESNA1-LF significantly reduces operating costs and provides optimum hardness rejection for softening applications, available in 4-inch and 8-inch diameter configurations
ESNA1-LF2 are designed to provide high rejection of natural organic materials and moderate rejection of total hardness, while running below 100 psi, offering energy and cost savings.
