Reverse osmosis is a water purification process that uses a semi-permeable membrane to remove impurities, contaminants and dissolved salts. By applying pressure, water is forced through the membrane, leaving behind impurities and obtaining purified water.
This process is based on the principle of natural osmosis, where water flows through a membrane to balance the concentration of solutes. In reverse osmosis, external pressure is applied to reverse this flow, filtering out impurities and obtaining pure water.
The reverse osmosis membrane has microscopic pores that allow water molecules to pass through, but retain larger particles such as salts, bacteria, viruses and chemical contaminants, resulting in high purity water.
