A highly-effective technology for reducing a wide range of both health-related and aesthetic contaminants, RO systems work by pressuring water up against a semi-permeable membrane that stops contaminants from passing but allows clean water to get through. Reverse osmosis systems offer a comprehensive means of eliminating more than 90 percent of potentially harmful contaminants in home drinking water including Cryptosporidium and Giardia.
Most RO systems are compact units installed under your sink. (In some cases, they can also be installed on the countertop). A typical system is comprised of one or more pre-filters, a reverse osmosis module, a post-filter and a pressurized holding tank
Tap water contains remnants of drugs, antibiotics and hormones. They can cause unpredictable damage to your health every day. Unfortunately, modern municipal sewage treatment plants are unable to completely remove these impurities from the water. Reverse Osmosis protects you against all harmful substances, contaminants, pesticides, herbicides including antibiotics and hormones, to maintain your health and well-being.
Reverse Osmosis Remove Minerals
Reverse Osmosis (RO) removed more than 90-99.99% of all the contaminants including minerals from the drinking water supply. RO removes minerals because they have larger molecules than water. The subject of minerals and RO created controversy and disagreement among water and health professionals. The World Health Organization (WHO) made clarification that majority of healthy minerals are needed for human body is from food or dietary supplementary sources and not from drinking tap water. In addition, minerals found in water can be harmful to human health. The evidence is strong that calcium and magnesium are essential elements for human body (WQA, 2011). However, its a weak argument to suggest that we should make up this deficiency through water consumption (WQA, 2011). Tap water presents a variety of inorganic minerals which human body has difficulty absorbing (Misner, 2004). Their presence is suspect in a wide array of degenerative diseases, such as hardening of the arteries, arthritis, kidney stones, gall stones, glaucoma, cataracts, hearing loss, emphysema, diabetes, and obesity. What minerals are available, especially in "hard" tap water, are poorly absorbed, or rejected by cellular tissue sites, and, if not evacuated, their presence may cause arterial obstruction, and internal damage .
Organic Minerals vs. Inorganic Minerals There are two types of minerals in water, organic and inorganic. Human physiology has a biological affinity for organic minerals. Most organic minerals for our body functions come from dietary plant foods . A growing plant converts the inorganic minerals from the soils to a useful organic mineral . When an organic mineral (from a plant food) enters the stomach it must attach itself to a specific protein-molecule (chelation) in order to be absorbed, then it gains access to the tissue sites where it is needed . Once a plant mineral is divested within the body, it is utilized as a coenzyme for composing body fluids, forming blood and bone cells, and the maintaining of healthy nerve transmission.
Reverse Osmosis has Little Affect on Water pH Water pH levels will automatically change when it is ingested and comes into contact with the food in your stomach . Even on an empty stomach, your stomach acid alone is already several times more acidic than RO water (pH 6-8) with a pH level of 2 . The human body regulates pH levels constantly to find balance and equilibrium. Therefore under normal conditions it will always maintain a neutral 7.4 pH balance. The healthy body is very robust and it will restore homeostatic pH fairly quickly and easily. Soft drinks and sports drinks typically have a pH level of 2.5, orange juice has a 3 pH and coffee has a 4 pH level and we drink these beverages all the time without problems.
Conclusion Water filtered or treated by RO is pure, clean, and healthy. RO treatment system is currently the only technology that can remove most of the emerging contaminants (i.e., prescription drugs and perchlorate) including other contaminants (i.e., Arsenic, Cyanide, and Fluoride) that are difficult to remove by other treatment methods. No more ingesting of harmful inorganic minerals means the body will no longer be stressed with trying to absorb something that wasn't supposed to be there in the first place. Consumers should not be concerned about the removal of minerals by RO system. WHO (2009) and WQA (2011) pointed out, that the human body obtains vast majority of minerals from food or supplements, not from drinking water.
