Familiarizing with Reverse Osmosis, the Different Types
When talking about reverse osmosis, one needs to understand what it is a reversed of. Osmosis is basically the movement of water from a high concentration to a low concentration through a semi-permeable membrane. In osmosis the water from a dilute solution will naturally move through a separating membrane to the concentrated side to equalize the concentrations of the both solutions.
Industrial Sector Increases Use of Reverse Osmosis
Reverse osmosis was introduced during the 1950s. It was promoted as an effective and safe process of purifying water as well as removing salts and many more impurities so that taste, color, and properties of the liquid could be further improved for greater potability. It is not surprising that within a span of just several decades, reverse osmosis for water purification has picked up so well that it is widely used in more than 100 countries now as a means for producing safer and more potable drinking water for growing population. The desalination (a reverse osmosis technique) market even grew to emerge as an $8 billion global industry.
Pros and Cons of Reverse Osmosis
Through the years, reverse osmosis has been widely used worldwide for treatment of water. Not all forms of water present in the surroundings could be potable and used for natural and household purposes. Through this process, water is purified by filtering out contaminants. Through the use of a semi-permeable membrane, reverse osmosis works upon application of external force or pressure. It should reverse the natural process of osmosis and force out pure water from a solution containing many contaminants or solutes. Of course, the advantage is quite logical: safer and more purified water is produced.
