three proven technology to reduce TDS
Reverse Osmosis (RO) remove TDS by forcing the water, under pressure, through a synthetic membrane. The membrane contains microscopic pores which will allow only molecules smaller than 0.0001 micron to pass through. Since the molecules of dissolved metals and salts are large compared to the water molecules, the water will squeeze through the membrane leaving the metals and salts behind.
A professional Reverse Osmosis system is capable of removing 90-99% of the dissolved mineral salts from water. A pre-filter is usually required to protect the membrane and remove organics.
The Pureoflow is a type of whole business or whole house reverse osmosis that is used as both a salt-free water softener, and a purifier. Whole house systems like the Pureoflow have the added benefit of protecting water heaters from corrosion, in addition to high quality drinking water.
Distillers are better known as “stills.” Stills work by heating small amounts (less than 2 gallons) of water to produce steam. The steam is then collected and condensed back into water. The dissolved mineral salts will not vaporize and are left behind in the heating chamber.
Stills require frequent, rigorous cleaning to remove the baked-on mineral salts. They also produce a “flat” taste and acidic water which has kept them from becoming a popular drinking water solution.
Deionization (DI) Systems pass water through a resin cartridge that attracts the dissolved solids, producing a high-purity water. Because DI cartridges have a limited life and require frequent replacement they are generally not used for high volume applications.
