Removal of undesirable chemicals, materials, and other biological components from raw water is called water purification and the device used is called water purifier. It is necessary to remove these unwanted particles from water to reduce the occurrence of many diseases. Water purifiers use various technologies such as UV and reverse osmosis. Reverse osmosis water purifiers are more efficient.

A reverse osmosis water purifier uses a selected membrane which allows water to pass through the other side of the membrane trapping the undesired materials present in water. This results in movement of solvent (water) from an area of higher concentration of solute (undesired particles) to an area of lower concentration of solute. This process is referred as reverse osmosis. An osmotic pressure is created across the membrane. The membranes are made of specific materials. Thin film composite (TFC) membrane and cellulose triacetate (CTA) membrane are the two types of membranes used by reverse osmosis water purifiers.

Size and capacity of reverse osmosis water purifiers vary based on area of use. Optimum filtration requires an osmotic pressure of 24 bar or 350 psi. Desalination or removal of salt from sea water is done by these water purifiers. They can also be used for many domestic, industrial and medical purposes. Specific reverse osmosis water purifiers are made by including specific customizations to remove rust, calcium carbonate solubles, chlorine and other organic chemicals.

Benefits of Reverse Osmosis Water Purifiers:

  • Disease causing microbes can be removed by these filters.
  • Hardness and bad taste of water can also be removed which improves taste of water.
  • There is no need to add any chemicals during the process of purification.
  • Any toxic by-products cannot be allowed to mix with purified water.
  • It is worth to use reverse osmosis water purifiers for home and industrial purposes.

Hence it is beneficial to use reverse osmosis water purifiers.
