What is an FRP filtration system?
An FRP (Fiberglass Reinforced Plastic) filtration system is a pre-treatment vessel that uses filter media such as silica sand, activated carbon, softener resin, or iron removal media to treat raw water before it reaches an RO system. It is designed to reduce sediment, iron, colour, chlorine, odour, and other contaminants in bore or untreated water, helping to protect downstream filters and extend the lifespan of the RO membrane.
Is a 6-stage RO system enough?
Yes. For most homes, villas, cafés, and small commercial use, a properly selected 6-stage RO system is sufficient. It includes sediment filtration, carbon filtration, RO membrane, UV sterilisation, and water storage tank. Additional stages are only required if water testing shows a specific problem.
Do I need an FRP system as well as RO?
Not always. A standard 6-stage RO system is usually sufficient for drinking water and food preparation when the incoming water quality is already reasonably treated.
An FRP pre-treatment system (such as sand, carbon, or softener filtration) is required when raw water quality is poor and would otherwise reduce RO performance, increase maintenance frequency, or shorten membrane lifespan.
Do I need both systems together?
Only if water testing confirms it. Installing unnecessary filtration increases cost, space, and maintenance without improving water quality.
BBS approach: test the water first, then recommend only what’s required.
