Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules.

Posted August 31st, 2016 & filed under Reverse Osmosis. It may not make our daily news but water crises happen often across America. Major cities turn to one of the best ways to make sure their citizens get clean water and that is with reverse osmosis.

Reverse osmosis (RO) water filters are not good for health according to a recent warning issued by the World Health Organisation (WHO). RO filters not just kills the bacteria, but removes all salts and essential nutrients such as calcium and magnesium. Cauvery water may not require an RO filter.

Reverse Osmosis (RO) removed more than 90-99.99% of all the contaminants including minerals from the drinking water supply (see Figure 1). RO removes minerals because they have larger molecules than water. Tap water presents a variety of inorganic minerals which human body has difficulty absorbing (Misner, 2004).

Water obtained from RO filtration process has a low pH value. Prolonged consumption of low pH water has adverse health effects such as increasing the risk of kidney disorders and gastrointestinal troubles. RO purifiers may reduce TDS levels below the recommended values, resulting in a negative impact on human health.

Water purified through such methods is the healthiest choice for drinking. Spring water still contains all of the essential minerals that are important for your health and also give water its taste. Other contaminants can also be present though, such as metals, nitrates, chlorine, and other chemicals.

The study concluded that four (yes, only four) bottled water brands have a pH and fluoride level completely safe for your teeth: Fiji, “Just Water,” Deer Park Natural Spring Water, and Evamor.
