Filtration vs. Reverse Osmosis: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 17, 2023
Filtration is a process of separating solids from liquids or gases using a filter medium, while reverse osmosis involves water purification by forcing water through a semi-permeable membrane.

Key Differences

Filtration is a physical or mechanical process used to separate solids from fluids by passing them through a filter medium. In contrast, reverse osmosis is a specialized filtration method that removes impurities from water by pushing it through a semi-permeable membrane.

The principle of filtration involves trapping particles larger than the pores of the filter medium. Reverse osmosis, however, operates by applying pressure to overcome osmotic pressure, allowing only water molecules to pass through a very fine membrane.

Filtration can be applied to various materials and fluids and does not necessarily require pressure or electricity. Reverse osmosis specifically targets water purification and typically requires external pressure to be effective.

In filtration, the efficiency and effectiveness depend on the pore size of the filter and the nature of the material being filtered. In reverse osmosis, the efficiency is influenced by the membrane's selectivity and the pressure applied to the system.
