A Reverse Osmosis (RO) system is a water purification system that uses pressure to force water through a semi-permeable membrane, removing dissolved salts, minerals, heavy metals, chemicals, and many other contaminants. RO is widely used for drinking water purification, desalination, industrial water treatment, and wastewater recycling.
How an RO System Works
A typical RO system includes several stages:
- Sediment Filter
- Removes sand, silt, rust, and other particles.
- Activated Carbon Filter
- Removes chlorine, odors, and organic compounds that can damage the RO membrane.
- RO Membrane
- The core component that rejects most dissolved solids and contaminants.
- Post-Carbon Filter
- Improves taste and odor before the water reaches the tap.
- Storage Tank (in many residential systems)
- Stores purified water because RO filtration is relatively slow.
Advantages
- Produces high-quality drinking water
- Improves taste and odor
- Effective for high-TDS water
- emoves a broad range of contaminants
- Commonly used for seawater desalination and industrial purification
