RO System Maintenance & Consumables Replacement Guide
Filter Media
Quartz sand, activated carbon and resin are essential filter media for RO pretreatment systems. They effectively remove suspended solids, chlorine and hardness ions. Recommended replacement period: every 18-24 months.
PP Filter
PP filters remove suspended particles and impurities before RO membrane filtration. Regular replacement ensures stable water flow, protects the RO membrane and improves system performance. Recommended replacement: every 1-3 months.
Chemical Dosing
Professional dosing chemicals protect RO membranes by preventing scaling, fouling, and biological contamination, improving system efficiency and extending membrane service life.
