Common failures & inspection points
Visual inspection for tears, cracks, or damage to the membrane surface; check for discoloration or degradation indicating chemical attack
Verify SDI (Silt Density Index) is below 5.0; confirm chlorine levels <0.1 ppm; test pH is within 2-11 operating range before system startup
Confirm system pressure does not exceed 41 bar (dSW) or 83 bar (dBW); monitor for sudden pressure drops indicating membrane damage or fouling
Ensure feed water temperature does not exceed 45°C (113°F); monitor for temperature fluctuations that could degrade membrane performance
Conduct baseline testing to confirm >99% salt rejection for dSW and 98-99.5% for dBW; perform periodic testing to detect membrane degradation or fouling
