Most of us have that water purification system in our homes, normally called as “RO”, but ever tried to understand the meaning of that “RO”? Well, it is the acronym of “Reverse Osmosis”, which is a water purification technique, applied to purify water from the alkaline or salt impurities. Reverse osmosis, as name suggest, is a reverse operation of osmosis, let’s find out what is osmosis first. Osmosis is the name for the tendency of water to migrate from a weaker saline solution to a stronger saline solution, gradually equalizing the saline composition of each solution when a semi-permeable membrane separates the two solutions. In reverse osmosis, water is forced to move from a stronger saline solution to a weaker solution, again through a semi-permeable membrane.
Because molecules of salt are physically larger than water molecules, the membrane blocks the passage of salt particles. The end result is desalinated water on one side of the membrane and a highly concentrated, saline solution of water on the other side. In addition to salt particles, this process will remove a select number of drinking water contaminants, depending upon the physical size of the contaminants. For this reason, reverse osmosis has been touted as an effective drinking water purification method.
Reverse Osmosis Plant or system was developed as a water treatment method more than 40 years ago. The process first arose as a technique of desalinating seawater. Once the method’s decontaminating capabilities were recognized, reverse osmosis plants began to be commercially produced for home water purification purposes. Such reverse osmosis plant was installed in homes as early as the 1970s. Reverse osmosis systems seemed a viable option to the more costly and energy-wasteful distillation units.
