Nano Filtration: State of the art water purification and most leading edge technology in water treatment is now available for practical use in your business or manufacturing facility.

Do your research : ask our competitors if their "salt free" well water softeners actually soften hard water or remove hard water minerals - ask if they guarantee that your water will be softer and test softer after their "no salt softener" - The answer may surprise you!  

Nanofiltration is a liquid separation membrane technology positioned between reverse osmosis (RO) and ultrafiltration (UF) A nanofiltration filter has a pore size around 0.001 micron. Nano Membranes provide high productivity performance while reducing a high percentage of salts, organic compounds, and hard water water minerals. The low net driving pressure NF membrane allows the removal of these compounds at low operating pressures - NF also removes hardness from water, which accounts for NF membranes sometimes being called “softening membranes” – NF is an attractive salt-free alternative to lime softening or zeolite salt regenerating type softening technologies.
Nano filtration water treatment is much the same as reverse osmosis technology. The key difference is the lower rejection levels - Nano Filtration is used where the high purity of reverse osmosis is not necessary – reverse osmosis systems can remove up to 99% of dissolved minerals, the nano membrane removes only around 75 to 80%. This means that the softened filtered water contains a partial mineral content which provides a good mineral taste while filtering excessive hardness, chemicals, nitrates, sulfates, pesticides, insecticides, and off taste components. Our Nano filtration systems offer a cost-effective alternative to commercial & whole house reverse osmosis units, as Nano filtration systems can be operated at lower operating pressures and typically do not require the addition of a separate water softener. The level of dissolved solids to be removed is less than what is typically encountered in brackish water or seawater. As such, Nano filtration is especially well-suited for treatment of municipal city tap water, well water, or water from surface sources like rivers and lakes.

System Options: Iron, Manganese, Chlorine Pretreatment Systems, Storage Tanks, Repressure Pumps
For well water users, iron and manganese are the enemies to nano membranes. These substances will accumulate on the membrane surface and clog the pore structure, not allowing water to pass through. Symptoms of this are decreased flow of product water over a relatively short time. Most good quality membranes last anywhere from three to five years depending on how much water passes through them as well as the quality of the unfiltered water. A water analysis will tell you which of these contaminants are present in high enough concentrations to warrant the need to employ some form of additional pre-filtration before the nano filter. If you suspect iron or manganese is present in your water, please fax or email us your well water analysis or contact us for a free water analysis test.
Chlorinated water supplies (typically city treated water) at no time should there be a Free Chlorine residual in the Nano feed water. Even very low levels of chlorine in the feed stream will result in irreparable oxidation damage of the nano membrane. We can provide a chlorine pretreatment filter quote upon request
Once installed - the purified water produced by the nano filter comes out as a small stream. A separate storage tank (at least 300 gallons storage or more is suggested) and a re-pressure pump is required to deliver the filtered water into your application. Use with your existing storage tank or contact us to find out what tanks and re-pressure pumps we have to offer.
