Reverse Osmosis
RO membranes are used to reduce dissolved substances in suitable applications. Recovery rate, reject water, membrane performance and post-treatment vary between models.

A practical guide to common water purifier technologies.
RO, UV, UF, sediment and carbon stages solve different problems. The final purifier should be selected from the actual input water, model specifications and intended use.
Technology overview
One purifier label does not explain the whole treatment process.
A purifier can combine multiple stages: sediment filtration, activated carbon, RO membrane, UV chamber, UF membrane, remineralisation or other model-specific stages.
Which stages are appropriate depends on the water source and water-quality information. This page is general guidance, not a substitute for laboratory testing or the manufacturer’s instructions.
Discuss Your Water SourceCommon purifier types
Know what each technology is designed to do.
Capabilities vary by product design. Always verify the specifications of the exact purifier model you are considering.
Ultraviolet
UV treatment is used for microbial disinfection when water clarity, dose and equipment condition are appropriate. UV does not remove dissolved salts.
Ultrafiltration
UF membranes physically filter very fine particles and microorganisms depending on pore size, but they do not remove dissolved salts in the way RO does.
Sediment filtration
Sediment stages help capture visible/fine particulate matter and can protect downstream components. Cartridge grades and replacement intervals vary.
Activated carbon
Carbon stages can reduce chlorine, taste, odour and certain organic compounds depending on design, contact time and water conditions.
RO + UV + UF and more
Combination systems integrate technologies, but more stages do not automatically mean a better fit. Evaluate the incoming water and exact model specification.
What to share
Prepare these details before asking for a recommendation.
Your enquiry becomes more specific and reduces the chance of selecting an unsuitable system.
Water source
Municipal, borewell, tanker or mixed.
Water test / TDS
Recent values if available, with test context.
Daily usage
Approximate household/workplace requirement.
Space & utilities
Wall/under-sink space, water line, drain and power.
Important: If water is suspected to be microbiologically or chemically unsafe, follow public-health guidance and use appropriate laboratory testing. A TDS meter alone cannot establish that water is safe to drink.
