Reverse osmosis is basically the opposite of a naturally occurring osmosis process. In the osmosis process solvent molecules pass through a semipermeable membrane from lower to higher concentration region to equilibrate the solute concentration between the two sides. In reverse osmosis process also, a semipermeable membrane is used to filter water. The semipermeable membrane used in reverse osmosis process allows removing ions, molecules and other particulates from water to make it potable. Here, an external pressure is applied to reverse the flow from of solvent from higher concentration to lower concentration region.
Reverse osmosis process can be used to produce extremely purified drinking or potable water containing only certain minerals. Reverse osmosis systems are found in both industries and households. With rising demand for water with increasing population, numerous small scale reverse osmosis systems that can be used for household purposes are available in the market. These systems can be fitted with the tap water source in your sink and you will get purified water right out of it. So, to help you buy the best reverse osmosis system, we have listed some great reverse osmosis systems below with their brief review. Continue reading
