Reserve Osmosis: you think that water in your glass is pure?
Author: boxieblueWithout going into chemical details, we will just note reverse osmosis as a filtration process used mainly for water. It is considered to be the safest water purification process. Yet, there are some hidden dangers to the reverse osmosis process.
First, in an attempt to leech out pollutants from the water, naturally occurring essential minerals are often leeched out as well. This is an unavoidable phenomenon, causing water to become too pure. In the absence of these minerals, which are chemically basic, water attains a slightly acidic nature (pH below 7). This causes the body to charitably offer minerals from its bones, weakening them over a long term. Further, consuming such water over a long term can cause diseases as deadly as cancer.
Further, substances which are smaller than water molecules themselves, as many herbicides are, are not removed. This means that reverse osmosis should not be used as the only purification method.
Not to mention the amount of water the process wastes! Performing reverse osmosis on a large scale is not the greenest way to purify water. Start drinking smart, and use methods other than reverse osmosis to purify your water. Combining it with UltraViolet radiation or distillation is recommended.
