Make life healthy with Reverse Osmosis

August 23rd, 2009  |  Published in Health, Technology

Water, that magical substance from which all life springs forth is essential to the very existence of every life form on earth. Water constitutes 70 percent of human body and water borne diseases account for 80 percent of all the diseases. Increasing pollution levels in the city, little control on ground water discharges by the industry and limited municipal water supplies are making conventional forms of water the need for contemporary Reverse Osmosis (RO) water purifying systems comes in.

RO is the finest water filtration method known. This process will allow the removal of particles as small as ions from a solution. It is used to purify water and remove salts and other impurities in order to improve the color, taste or properties of the fluid. RO uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting other ions and contaminants from passing. This technology uses a process known as cross flow to allow the RO membrane to continually clean itself.

This is the reason why an RO element can last many years before clogging or need replacement. This water purification process requires a driving force to push the fluid through the membrane, and the most common force is household water pressure or pressure from a booster pump. The higher the pressure, the larger the driving force and efficiency.

Is it Reverse Osmosis water safe to drink?

RO water is perfectly safe to drink. There is also a scientific explanation as to why this type of purified water is actually better for you than water that contains high mineral (TDS) content. Water with a high TDC count of over 50 ppm, actually becomes electrically charged and can conduct very small amounts of electric current. High TDS water, under the right circumstances, can actually cause a small electric light bulb to become illuminated! Water with high TDS is typically a solution that is lacking in hydrogen molecules. This type of water often causes de-hydration on the cellular level. Reverse Osmosis with low TDS on the other hand, has a much lower ability to conduct electrical charges. Typically, RO water is slightly acidic and loaded with positively charged hydrogen (H+) molecules.

 What’s the difference between conventional water filtration and RO?

A conventional filtration system, such as that in a refrigerator for instance, will give you nice tasting water, but it will not remove Total Dissolved Solids, such as, sodium, manganese, calcium carbonate, to name a few, that are present in most municipal tap and well waters. Residential reverse osmosis systems typically incorporate a combination of conventional filtration to remove sediment and other solids, followed by activated carbon adsorption for the removal of organic compounds, chlorine, pesticides and VOC’s, prior to the reverse osmosis membrane. The end result is as close to distilled water quality as you can get, with virtually no energy consumption. The typical household water line pressure of 40 psi is all the energy that is required to make the RO system work.
