Water, water everywhere, and not a DROP TO DRINK… How does your water taste? Does your water contain Chlorine? Do you buy bottled $$$$$$$$ water?
What other chemicals are added to water supplies running through antiquated, sometimes leaded, pipes into your home or business?
Reverse Osmosis Filtration is for all water systems, private and public, and requires no harsh chemicals!
Reverse osmosis filtration cleans water by taking out the totally dissolved solids (TDS) which contaminate the water. Although public water treatment removes the dirt and debris and adds chlorine to prevent the spread of diseases, it does not remove the dissolved solids from the water. And with the increasing pollution of our surface and ground water with contaminants such as lead, mercury, and chromium-6, as well as the naturally occurring harmful contaminants such as arsenic, fluorides, and sulfides found in some areas of the country, it is more important than ever to have a way to remove these contaminants at the point of use–your home!
Reverse Osmosis membranes used in water filtration systems can on average remove 95% of dissolved contaminants from water (see table on right). Only 1% of the city water entering the home is used for drinking and cooking—about 2-3 gallons per day—where the average home used 300 gallons per day or more. So it makes sense to treat the whole house for dissolved calcium for efficiency of detergents and protection in personal hygiene, then to micro-filter drinking and cooking water with RO. Public and private water systems both have the required pressure of 60-70 psi to make the reverse osmosis system work properly.
Reverse Osmosis is a naturally occurring process in human and animal membranes. Salts in the body fluids build up osmotic pressure, forcing water molecules through the living membranes in our bodies. In under-sink reverse osmosis systems, pressure from the city water overcomes the “salt” pressure of the dissolved materials and forces the water molecules through a thin, synthetic film membrane, leaving the dissolved salts behind. The city/county water enters the membrane filter element, and two streams leave; the clean water and the water containing the dissolved solid residue, called brine, which is discarded to the drain. RO removes the smallest of materials, from 1-micron down to 1-Angstrom. For materials larger than 1 micron, particle filters are used ahead of the RO membrane to prevent plugging of the tiny membrane pores.
