Frequently Asked Questions: Industrial Water Filtration Sri Lanka

How often should activated carbon and sand media be replaced in Sri Lanka? +
Filter sand typically lasts 3 to 5 years with regular backwashing, although calcified or silt-choked sand should be replaced sooner. Activated carbon typically exhausts its adsorption pores within 12 to 18 months under typical Sri Lankan municipal or well water conditions (especially when removing free chlorine and organics). Water Lanka offers routine iodine value testing and islandwide re-bedding services.
Why choose an FRP pressure vessel over a concrete or mild steel vessel? +
Fiberglass Reinforced Polymer (FRP) vessels are 100% immune to corrosion from brackish water, salinity, and chemicals, unlike mild steel which eventually rusts. FRP vessels are also lightweight, easy to transport and install, and capable of operating at up to 10 bar (150 psi) with zero maintenance for over 15 years.
