Reverse osmosis (RO) systems are water purification technologies that remove contaminants from water by using pressure to force water molecules through a semipermeable membrane. This process separates impurities and dissolved solids from the water. Here’s how it works:
- Pressure Application: Water is pressurized to overcome natural osmotic pressure, pushing it through the RO membrane.
- Semipermeable Membrane: This membrane is designed to allow only water molecules to pass through, while blocking larger molecules and impurities, such as salts, bacteria, viruses, chemicals, and minerals.
- Contaminant Removal: As water passes through the membrane, contaminants are filtered out and flushed away, leaving purified water.
- Post-Filtering: After passing through the membrane, the water often goes through additional filters, such as carbon filters, to remove any remaining tastes and odors.
RO systems are used in various applications, including residential drinking water purification, industrial processes, and wastewater treatment. They are effective in producing high-quality, clean water, especially where the removal of dissolved minerals and chemicals is necessary.
