What Is Reverse Osmosis?
Reverse Osmosis (ro) is one of the most convenient and economical methods of reducing unwanted contaminants in your drinking water. Reverse Osmosis is the process by which water molecules are forced, by water pressure, through a semi-permeable membrane. Most of the impurities and other contaminants are rinsed to the drain while refined water is routed to a special holding tank for future use.
The Principle of Osmosis
Osmosis is the exchange of dissolved substances through a semi-permeable membrane. When for example, water with different concentrations is separated by a semi-permeable membrane, the weaker solution will be forced through the membrane to dilute the higher concentration until measurable pressure is created. This pressure is referred to as osmotic pressure.
The Principle of Reverse Osmosis
This procedure can also take place in reverse by building up such high on the concentrated side (tap water) that the osmotic pressure is overcome. The solution is now forced through the membrane in the reverse direction, with only the solvent (water) actually passing through, not the dissolved substances. This membrane functions as an ultra-fine filter which is capable of separating out even superior molecular substances such as:
VIRUSES, BACTERIA AND PYROGENES
No other process, whether chlorination, oxidation with ozone, UV-irridation or activated carbon filter, ceramic or distillation has the same positive influence on the purification of water.
What Is the Membrane And How Does It Work?
The membrane consists of several thin layers of sheets of film that are bonded together and rolled in a spiral configuration around a plastic tube. (This is also known as a thin film composite or TFC membrane). The material of the membrane is semi-permeable; it allows water molecules to pass through while acting as a barrier to dissolved solids (i.e., mineral and chemical contaminants). The pores of the membrane are too small for the contaminants in water to pass through them. A high quality membrane will prevent even the smallest bacteria from entering your drinking water. The pores of the membrane are undetectable even to the scanning electron microscope at 8000x magnification. The pore size of an RO membrane is .0006 of a micron.
What Happens To The Contaminants?
The reverse osmosis process cannot go on indefinitely without removing the contaminants. Ultimately the membrane could become clogged by salt and other impurities, requiring increasingly greater pressure to force water through the membrane. To solve this problem, the membranes are configured to split the feed water into streams - one part to be purified and the other part to wash away the particles rejected by the membrane.
What Is The Actual Process Of The Reverse Osmosis System?
With Dr. Guberman's reverse osmosis system, the raw tap water first flows through a 10 micron Carbon Filter to remove dirt, rust and other sediment as well as 98% of the chlorine and organic chemicals. The next stage of the process is the reverse osmosis membrane which will separate 70-99% of the dissolved contaminants from the water molecules. The contaminants are then washed down the drain. The next stage of the process is the carbon post filter that removes the remaining traces of chemical tastes and odors. The RO water is then stored in a 3.2 gallon tank for immediate use by holding the handle down on the kitchen counter or sink installed spigot.
What Will Reverse Osmosis Remove From Your Tap Water?
Here are but a few of what RO removes:
Herbicides Pesticides Benzene Fluoride Lead Mercury Nitrate Radium Radon Barium Cadmium Cyst reduction Ionized salts Chlorides Sulfates Arsenic Asbestos Bacteria Fungus Virus Trichlorethylene Trihalomethane
Our unit will make 50 gallons per day of pure water free of harmful chemicals. Here are the rejection rates for our Reverse Osmosis Filtration system:
Aluminum: 96-97% Arsenic: 94-96% Bacteria: 99+% Barium: 96-98% Cadmium: 95-97% Calcium: 94-97% Chlorine: 90-95% Copper:96-98% Cyanide: 90-95% Fluoride: 93-95% Hardness: 90-95% Iron: 97-98% Lead: 96-98% Magnesium: 95-98% Manganese: 94-96% Mercury: 95-97% Nitrate: 92-95% Phosphate: 97-98% Silver: 95-97% Sodium: 94-98% Zinc: 96-98%
Because coffee and tea are 99% water, they are no better than the water which they are made in. Imagine better tasting coffee, tea and clearer ice cubes. Your plants and pets will love it too.
