RO: Reverse Osmosis

RO is an abbreviation of Reverse Osmosis. It is a course of action that aids the RO water purifier to banish unfavorable ions, dissolved solids, and TDS from the water. Reverse osmosis is the contrary of osmosis. From a less concentrated solution to a more concentrated solution, a solvent moves through a semi-permeable membrane in osmosis. In the case of the direction of reverse osmosis, in a contrary direction from a more concentrated solution to low concentrated solution the solvent passes through the semi-permeable membrane. By the pump of the RO water purifier, the pressure needed to move solvent which is water from more concentration solution which is a solution of tap water to low concentration solution which is purified water is produced.

  • RO without a phase change executes a severance. Therefore, the demands of energy are less as the demand of energy depends on the phase change.
  • RO systems are dense, and in comparison with other desalting systems, space demands are less, e.g. distillation.
  • RO equipment is systematized - pumps, motors, valves, flow meters, pressure gauges, etc. Therefore, the learning curve for untrained labor is small.
  • Various RO systems through interlocks are fully programmed and created to automatically start-up and shutdown. Therefore, RO plants generally need very little labor.
  • Maintenance is effortless because of its modular design. Execution of Scheduled maintenance can be done without closing down the complete plant.
  • The modular design also makes development a simple choice.


  • RO is generally not valid for concentrated solutions because of the high-pressure constraint.
  • The RO procedure generally cannot be functional without pretreatment because all RO membranes and devices are vulnerable to contamination.
  • RO eliminates mineral which is natural such as iron, magnesium, calcium, and sodium which are vital to the human body and are the source of a mineral insufficiency in the body.
  • Waterborne diseases which are the source of bacteria and viruses do not kill by the RO water purifier. Through the RO membrane, there is a high possibility that microorganisms can pass, which makes RO water suitable to pass for the treatment of microorganisms through the UV water purifier.
  • Removal of natural minerals makes the water de-mineralized and as a consequence of that water, the taste gets affected which makes it becomes insipid.
  • For the refinement of water, RO water purifier takes too much time.
