- Normalized data: Temperature and pressure correction reveals true membrane performance trends
- Alarm setpoints: High pressure, low flow, conductivity excursion, and chlorine detection trigger automatic shutdown
- SCADA integration: Remote monitoring enables predictive maintenance and reduces site visits
Membrane Cleaning Protocols
Regular cleaning maintains membrane performance and extends service life:
- Cleaning triggers: 10-15% permeate flow decline, 15% pressure drop increase, or 10% salt passage increase
- Acid cleaning: 2% citric acid or 0.5% HCl removes mineral scale (calcium carbonate, iron, manganese)
- Alkaline cleaning: 0.1% NaOH with EDTA or surfactants removes organic fouling and biofilm
- Cleaning frequency: Every 3-6 months depending on feed water quality and pretreatment effectiveness
