Featured Livestock & Agriculture Products: Nano Water Filtration

Animal, Equine, & Livestock Drinking Water Filters: Horses, Mules, Dairy & Beef Cattle, Goats, Sheep, Pigs, Chickens, Ducks, Turkeys


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.

Portable Water Filters - The RDWS-TPC Nano series of purification systems provide clean, healthy drinking water for horses and other livestock as well as filtered water for greenhouses, organic gardens, beer brewers micro & craft beer breweries, or 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. Learn more here

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.  Learn more here
