  • RO Purification eradicates All Essential Minerals from Water
  • RO Purification diminishes the pH Level of Water

Come on, don’t start looking for other alternatives and Water softener cost before you get to the details of RO. Below you can have a look at the details of RO and these draw backs that have been associated with this best water softeners system.

RO Purification eradicates All Essential Minerals from Water

It is a hugely known fact that RO purification not just eradicates harmful contaminants such as disease triggering microorganisms and harmful heavy metals such as lead, mercury, arsenic etc. but also eradicates some essential minerals such as calcium and magnesium. This is because the size of the molecule of the minerals is huger as compared to that of water and RO membrane just allows water molecules to pass through it because of such a fact, some individual’s claim that since RO eradicates these essential minerals from the purified water, hence RO water is not great for your health. Presence of heavy metals like iron creates many problems in the body, hence removing them is very important. Check out for best iron removal softners in the market.

There is no denying the reality that minerals like calcium and magnesium are important and necessary for the body and RO purification does eradicate these during purification. But it is also absolutely true that no other water purification technique is as effective and as hugely used as that of RO purification.

RO Purification diminishes the pH Level of Water

RO purification also diminishes the pH level of water. Once water is passed through a semi-permeable RO membrane, various organic and inorganic constituents fail to pass through, though gases like Carbon Dioxide (CO2) pass through RO membrane. CO2 linked up with the free Hydroxide ions (OH-) in water to create acidic Hydrogen Carbonate or bicarbonate ions (HCO3), whereas the Hydrogen ions (H+) fail to search any substance to react with as most of the scums are removed through the RO membrane. As a result of this, water has a positive balance of H+ ion, dropping its pH and making it acidic. The more the amount of CO2 in the water, lesser is the pH level. However, your body does a wonderful job of managing a near neutral pH of 7.4 at all the times. Once you consume slightly acidic water, it loses its acidity the moment it encounters saliva in your mouth and food in the stomach. In case you are suffering with any type of health issues or are trying to lose weight, then you must stop consuming acidic and sugar-added drinks. You should consume pH-neutral or slightly alkaline water for upholding a proper acidic balance in your diet.

What is the Smallest Level of Minerals or TDS in Drinking Water?

Most of the nations around the world including India have well-defined maximum acceptable restrictions of inorganic and organic substances to assure the safety of drinking water you know absolutely little modern research has been done to set guidelines for the least quantity of minerals or TDS in water. However, it should not be forgotten that the importance of minerals and other beneficial ingredients in drinking water has been present for thousand years, being mentioned and talked about in the Vedas of ancient India.

The report by WHO (World Health Organization) published in the year 1980, recommended that the minimum TDS in drinking water has to be 100 mg/L. The best TDS should be nearly 200-400 mg/L for that of chloride-sulphate waters and 250-500 mg/L for that of bicarbonate waters. Water having TDS of twenty five to fifty mg/L was described tasteless.

Apart from the TDS levels, the report recommended that the least calcium content of drinking water has to be thirty mg/L. The same report also discloses European countries like the Czech Republic and Slovakia accepting the optimum magnesium level of ten to thirty mg/L in the drinking water.

Possible Damaging Effects or Disadvantages of Drinking De-mineralized RO Water for Long

As per a WHO report published in 1980, de-mineralized water or low-mineral water is not believed to be ideal and its day today consumption may result in a lack of some essential minerals. The study showcased that drinking water that is deficient in calcium or magnesium could end up in several health consequences such as a high risk of Cardio Vascular ailments. The research also discovered that drinking water low in magnesium could be associated with a higher risk of motor neuronal disease, sudden death in infants, pregnancy disorders, and some kinds of cancer.

On the other hand, some recent studies suggest that drinking water that has a low value of calcium heads to higher danger of bone fracture in children, low weight at birth and premature birth and some kinds of cancer.

Does it mean you should Stop Using RO Purifiers?
