Understanding Reverse Osmosis (RO)
Reverse Osmosis, abbreviated as RO, is a water filtration process that uses a semi-permeable membrane to remove dissolved salts, impurities, heavy metals, bacteria, and other contaminants from water. The process works by applying pressure to water, forcing it through the membrane. Only pure water molecules pass through, while impurities are left behind.
The term “reverse osmosis” is used because it reverses the natural osmosis process. In natural osmosis, water moves from a low concentration of solute to a high concentration. RO does the opposite, moving water from a high concentration of impurities to pure water, making it ideal for water purification.
RO technology is widely used for domestic, commercial, and industrial purposes, ensuring clean and safe water for various needs.
How Does RO Work?
An RO water purifier works in multiple stages to provide safe drinking water. Each stage has a specific function:
| Stage |
Function |
| Pre-Filtration |
Removes dust, rust, and sand particles from water. |
| Activated Carbon Filter |
Eliminates chlorine, bad odor, and organic chemicals. |
| RO Membrane |
Blocks dissolved salts, heavy metals like lead, mercury, arsenic, and microorganisms. |
| Post-Filtration / TDS Controller |
Enhances taste and ensures safe water. Some modern RO systems also add essential minerals back. |
