‌Maintenance focus‌: Monthly detection of anode membrane permeability (standard value <15%)
Replacement of ultrafiltration membrane chemical cleaning agent (nitric acid + surfactant) every quarter
Calibration of electrode potential sensor every year
Note: Safety requirements‌
Anti-leakage fences must be set up around the tank (insulation resistance >100MΩ)
LEL concentration monitoring must be installed at the exhaust outlet (explosion lower limit warning value <25%)
Emergency power supply must ensure continuous operation of the circulation system for ≥30min
