MBR Membrane Chemical Cleaning Dosing
Summary: How to set up chemical dosing for MBR membrane cleaning: common chemicals for maintenance and recovery cleaning (NaOCl, citric or hydrochloric acid) and metering pumps grouped per membrane train with flow meters and PLC timers.
Why Standardized Dosing
Membrane fouling is the main irreversible loss; scientific online/offline cleaning extends membrane life greatly.
Chemicals
- Online (maintenance): NaOCl 200-500 mg/L, short periodic dosing
- Offline (recovery): alternate NaOCl and citric/hydrochloric acid soaks
Configuration
Metering pumps per membrane train, with flow meters and PLC schedules for fully automatic maintenance cleaning.
