Hyde energy ESNA1 series nanofiltration membrane：
U.S. Hydranautics ESNA launched in 1996, energy-efficient nanofiltration membrane can effectively removing hardness, iron, color, and chloroform (THM) and other substances, and at very low pressure can also be obtained through the high water volume. Low-voltage operation not only saves energy, and associated pumps, piping and pressure vessels and other ancillary equipment is also cheaper, ESNA series of membrane modules of the advantages of growing users of all ages.
In 2004, Hydranautics will clean performance nanofiltration membrane technology with the organic combination of the original ESNA1 nanofiltration membrane modules, based on the development of neutral ESNA1-LF and ESNA1-LF2 products . Both nanofiltration water conditions can be complex in some applications a stable operation.
