    NEWater Nanofiltration Membranes

    As mentioned earlier, our Nanofiltration Membranes are pressure-driven. They have a 90 percent rejection capacity of substances with a molecular weight of 200 to 1000 Da. Their pore diameters range from 0.1 to 1 nm, and they can easily operate at pressures of 5 to 15 bar.

    Nanofiltration Membrane9

    Our Nanofiltration Membranes are composed of thin films of organic material. They can operate at lower pressures compared to reverse osmosis membranes and they have the ability to much more selective rejection of impurities based on their size and their charge. And they may be composed of materials that include polycarbonate, polyimide, and cellulose acetate along with others based on your requirements.

    NEWater’s Nanofiltration Membranes have a high rejection capacity for salts, which has an order of highest rejection of Na2SO4, then CaCl2, and then finally NaCl, also referred to as sodium chloride or table salt.

    Nanofiltration Membrane10

    Our Nanofiltration Membranes are employed in a variety of machines, that are used in a number of application areas. These include both wastewater treatment and the production of fresh and healthy drinking water. They can also be used to recycle water. They are used to treat a variety of alternative water sources such as saline water, brackish water, groundwater, and surface water.

    The process that our Nanofiltration Membranes are employed in begins with the screening of the raw water, after which coagulation and flocculation are carried out, which then leads to sedimentation. Once larger impurities are removed then nanofiltration is carried out, which can then be followed by the removal of unwanted odors and tastes, and disinfection.

    Nanofiltration Membrane11

    Thus, our Nanofiltration Membranes here at NEWater are ideal for water treatment and purification. They not only have the ability to take part in the desalination process but also lower the turbidity and hardness of water, fraction out dissolved salts, and along with all these advantages, they also remove microorganisms from the water.
