Here is a brief description of the RO system works:

Pre-filtration: The first step in an RO system is pre-filtration. This is usually done with a sediment filter that removes larger particles such as sand, silt, and dirt from the water.

Carbon Filtration: The second step is carbon filtration, which removes chlorine and other organic compounds that can affect the taste and odor of the water.

RO Membrane: The heart of the RO system is the semipermeable membrane, which is a thin film composite membrane that separates the pure water from the impurities. The membrane is designed to allow only water molecules to pass through while rejecting larger molecules and ions.

Post-Filtration: The final step in an RO system is post-filtration, which is done with a carbon filter. This removes any remaining taste and odor from the water before it is dispensed.

Storage: After passing through the filtration stages, RO water is stored in a tank for later use.

Distribution: When required, RO filter water is distributed in the tank with the help of a faucet or dispenser.
