According to ESAI Membrane Technology Report 2023, properly maintained UF systems achieve 85% cost-efficiency improvement. This guide reveals maintenance frameworks adopted by Fortune 500 manufacturers, compliant with ISO 23447:2021 standards.
1. Commissioning Phase Protocol
● Execute "3-stage ramp-up": Maintain 60% flux for first 24hrs with precise temperature control (20±2℃)
● Case Study: Petrochemical plant reduced membrane replacement costs by 33% using this method
2. Operational Monitoring Essentials
● Feedwater criteria: Turbidity ≤0.5NTU, SDI15＜3, TOC＜3ppm
● Smart backwash adjustment: Implement IoT-enabled controllers responding to TMP fluctuations
3. Preservation Strategies
● Short-term shutdown: Daily air-water mix backwash (0.12MPa, 1.8m³/h)
● Long-term storage: Preserve with 1% sodium metabisulfite solution, monthly pH monitoring
Physical Cleaning Matrix
Chemical Cleaning Algorithm
● Organic Fouling → Alternating 0.3% NaOH/NaClO
● Inorganic Scaling → 3% Citric Acid (pH2.3)
● Biofouling → 800ppm Peracetic Acid Shock
Implementation case: 89% flux recovery rate achieved in desalination plant
● Install multi-parameter sensors: Real-time tracking of TMP, ΔP, flow asymmetry
● Build chemical consumption database: Record cleaning agent dosage & efficacy
● Predictive maintenance: Machine learning models forecast membrane lifespan (accuracy＞92%)
