Protect Membranes. Preserve Performance.
RO performance depends on everything that happens before and around the membrane. C-Water connects pretreatment, filtration, chemical protection, RO, monitoring and optimization into one treatment strategy.
Critical Operating Challenges in RO & Membrane Systems
Colloidal & Particulate Fouling
Silt Density Index (SDI) elevation from suspended solids plugs lead membrane elements and spikes feed pressure.
Mineral Scaling (Silica, Calcium, Barium)
Concentration polarization on tail elements precipitates insoluble salts, causing irreversible membrane flux loss.
Biological Slime & Biofouling
Nutrient-rich feedwater feeds bacteria that build protective extracellular polysaccharides, causing massive differential pressure.
Frequent, Degrading Clean-in-Place (CIP)
Unstable operating conditions necessitate constant acid/caustic CIP cycles, shortening membrane lifespan from 5 years to under 18 months.
