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 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.


Nano filtration systems are used for home drinking water filtration & salt free water softening, equine, livestock, dairy and cattle farming, manufacturing business, food, pharmaceutical, municipal, lake, river, well water applications, reclaim water, run off water  from farms, Commercial Water Treatment For Growers. 

The Stockwater series of purification systems provide clean, healthy drinking water for livestock in areas where the available water supply contains high levels of minerals or other undesirable contaminants. The key features of the Stockwater models are portability, simplicity, rugged design, and the ability to operate on typical tap or well water line pressure.

The Stockwater series of purification systems provide clean, healthy drinking water for livestock in areas where the available water supply contains high levels of minerals or other undesirable contaminants. The key features of the Stockwater models are portability, simplicity, rugged design, and the ability to operate on typical tap or well water line pressure.

The Stockwater systems can be wheeled out to greenhouses, gardens, barns, corrals and other livestock areas, connected to a water supply hose and turned on to supply fresh, good tasting water to troughs or other watering containers. The most important part of the Stockwater system 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 Stockwater membrane removes only about 80 to 90%. This means that the Stockwater purified water contains the partial mineral content vital for health and good taste while eliminating excessive hardness and off taste components which can cause lower than normal hydration in livestock. 

The Stockwater systems include a welded all stainless steel frame and pressure vessel, integrated aluminum dolly cart with 8” wheels, dual 2.5”x20” sediment and carbon block prefilters, prefilter in and out pressure gauges, 4”x40” special membrane filter element(s), ” standard hose feed water connectors, ” tube cam lock product and drain connectors, digital electronic water purity monitor for feed and product water, and combined flow restrictor/membrane flush valve. The pressure gauges provide an indication of prefilter condition and feed water pressure while the water quality monitor shows the mineral content of both feed water and product water allowing verification of proper membrane operation.
