Water Challenges: Sodium and chloride ions, which make up salt, can cause a variety of unwanted environmental issues from damaging the aquatic and marine ecosystem (oceans, rivers, lakes) to altering the fine biochemical stability in the soil. Eradicating the usage of salt within the water treatment process can be are very costly. However, investing in a nanofiltration system will not only soften water without the usage of salt, but also remove other particles and parameters present in the water without leaving the discharge of the system beyond municipal sewage guidelines. Pure Aqua manufactures nanofiltration systems which utilize catalytic-conversion media to neutralize sodium, calcium and magnesium, including minimizing scaling.

Applied Solution: Nanofiltration systems are used for the removal of contaminants from water sources as well as for reducing big ions. Nanofiltration (NF) is a cross-flow filtration technology that falls between ultrafiltration (UF) and reverse osmosis (RO). The membrane has about a 1 nanometer nominal pore size. Nano filter membranes are usually rated by molecular weight cut-off (MWCO) instead of nominal pore size. The molecular weight cut-off is usually less than 1000 atomic mass units (daltons). The pressure drops across the membrane (transmembrane pressure) required is lower than the one used for a reverse osmosis system leading to a significant reduction in operating cost. Because nano filter membranes are still susceptible to scaling and fouling, including an antiscalant dosing system is highly recommended to preserve the longevity of membrane life. Nanofiltration (NF membrane) functions similarly to reverse osmosis or RO membrane, but is generally targeted to remove only divalent and larger ions. Monovalent ions such as sodium and chloride will pass through an NF or Nano filtration membrane, therefore many of its uses involve de-salting of the process stream. In the production of lactose from cheese whey, for example, NF Filtration System concentrates lactose molecules while passing out salts, a procedure that purifies and concentrates the lactose stream. In water treatment, NF membranes are used as a softening membrane for hardness removal (in place of water softeners), pesticide elimination, and color reduction. It can also be used to reclaim spent Sodium Hydroxide NaOH solutions, in which case the permeate stream is purified NaOH, allowing reuse many times over.

    Works well and our team maintains the NF system very well too. System came with very detailed manuals that are easy to follow. Great buy.
