NANO MEMBRANE OPTION Each of the RainDanceH2O-TV systems can be equipped with NANO membranes instead of the standard reverse osmosis membranes. NANO membranes provide a significant electric power savings (up to 40% less) than reverse osmosis membranes with only a moderate increase in permeate TDS level. NANO membrane work especially well when the principal feed water mineral problem is hardness.

The benefit of nano membranes instead of R.O. membranes depends largely on your feed water quality. If the feed water problem is mainly hardness (calcium, magnesium, sulfate) then nano's will do a good job and use less energy (watts). If the problem is more due to  things like arsenic then R.O. is a better choice.  Nanos will make product water that is moderately higher in TDS compared to R.O. membranes. The 1/2 HP pump on our nano system will use less electric power than the 3/4 HP pump that is needed on the R.O. systems.

The most important part of our nano systems is the special membrane that creates the purified water.  Unlike the membranes used in most reverse osmosis systems which remove up to 99% of dissolved minerals the nano membrane removes only about 80 to 90% (nominal).

Nano Membranes provide high productivity performance while removing 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 - applications include drinking water - water softening - commercial business - farming - agriculture - livestock - greenhouses - horses and all other animals. Visit our Commercial 2000gpd up to 12,000gpd  Nano-Filtration Water Treatment Selection Guide at

What is the difference between Nano Filtration & Reverse Osmosis?


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 salt rejection of reverse osmosis is not necessary. 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 pressures and provide hard water softening as known as "membrane softening". 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.


Our Nano filtration systems are capable of removing a high percentage of water hardness (calcium and magnesium) Nano filtration is also used to remove pesticides and other organic contaminants from surface and groundwater.  Nano filtration is also an alternative to salt based water softening. NANO Advantage: lower investment costs and lower energy costs! Compared to conventional softening, operation costs are considerably reduced as expensive water regenerations with large salt amounts becoming obsolete.


We know it can be overwhelming wading through mounds of information when selecting a nano filtration system. Before long your brain is abuzz with different competitors, options, custom features, and terminology. Our experienced nano membrane water treatment support/design team is here to help you understand and address any questions or concerns that you may have Contact us at: - Our support/design team will answer your questions or concerns 7 days a week, typically within minutes with honest easy to understand answers before and after your purchase. We believe in an educated buyer who will buy the water filter he/she needs, with ultimate long term satisfaction
