Salt Free Well Water Softeners & Filtration Systems - Nano-Membrane Well Water Softening Systems   

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, nitrate, and organic compounds such as pesticides, herbicides and THM precursors. 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 alternative to lime softening or zeolite salt regenerating type softening technologies.

 Reduces salts & total dissolved solids (TDS)
 
Reduces heavy metals
 Reduces pesticides, herbicides, insecticides
 Reduces nitrates & sulfates
 Reduces uranium & radium
 Reduces fluoride
 Reduces color, tannins, and turbidity
 Softens hard water (calcium & magnesium minerals) without salt
 Filters bacteria, viruses, giardia, cryptosporidium, cysts

What is the difference between Nanofiltration (NF) & Reverse Osmosis (RO)?

Nanofiltration water treatment is much the same as reverse osmosis technology. The key difference is the lower rejection levels - NF is used where the high salt rejection of RO is not necessary. Our Nanofiltration systems offer a cost-effective alternative to commercial & whole house reverse osmosis units as NF systems can be operated at lower pressures and provide hard water softening, known as "membrane softening", a salt-free alternative to salt-based water softeners. 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.

The benefit of nano membranes versus RO membranes depends largely on your feed water quality. If the feed water problem is mainly hardness (calcium, magnesium, sulfate), then nano membranes work well and use less energy (watts). If the feed water problem is high arsenic or similar water quality concerns then RO is preferred. Unlike the membranes used in most reverse osmosis systems which remove up to 99% of dissolved minerals, the nano membrane removes only 80-90% (nominal). NF systems also provide high productivity performance while removing a high percentage of salts, nitrate, and organic compounds such as pesticides, herbicides, and THM precursors.

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.
