    • NF Nanofiltration Membranes For Water Treatment

    Short Description

    The operation range of nanofiltration membrane filter cartridge is between ultrafiltration and reverse osmosis,

    Function:

    ♦ Micron Rate: 0.001 μm

    ♦ Salt Rejection Rate: NaCl 30%-50%, MgSO4>96%

    Details

    Nanofiltration membrane has the selective desalination mechanism for removal of high polyvalent ions and partial maintaining of monovalent ions with health benefits. Moreover, the FNFM membrane elements can achieve as the high rejection, ultra-low operating pressure for desalination of raw water with low salt concentration.

    NF Nanofiltration Membranes For Water Treatment

    Application

    Nanofiltration membranes can effectively reject, among other contaminants:

    ♦ Dissolved organics

    ♦ Endotoxins/pyrogens

    ♦ Insecticides/pesticides

    ♦ Herbicides

    ♦ Antibiotics

    ♦ Nitrates

    ♦ Sugars

    ♦ Metal ions

    ♦ Latex emulsions

    ♦ Textile

    ♦ Whey / Whey Permeate

    ♦ Caustic cleaning solutions

    ♦ Antibiotics

    ♦ Recycle of acid solutions

    ♦ food & beverages manufacturing

    ♦ pharmaceuticals manufacturing

    Typical applications of nanofiltration membrane systems include:

    The removal of color and total organic carbon (TOC) from surface water.

    The removal of hardness or radium from well water.

    The overall reduction of total dissolved solids (TDS).

    The separation of organic from inorganic matter in specialty food* and wastewater applications.

    Features:

    The primary distinction is that nanofiltration is not as rigid as reverse osmosis. It functions with less feed water pressure and is incapable of removing single charge ions from the water as definitely as reverse osmosis membranes.

    Nanofiltration is the preferred choice for removing hardness from water while not affecting the total dissolved solids content than would reverse osmosis.id solutions
