The main reasons that the curtain type MBR membrane module is likely to be blocked in winter are as

Operating temperature (temperature: 10-35℃, bacteria in the membrane pool will not survive when it is too high or too low)

Designed sludge concentration ( MLSS range: 5000-12000mg/L )

Maintenance and cleaning (maintenance: 1 ton of water for 5KG medicine; recovery: 1 ton of water for 30KG medicine)

Imported Mitsubishi Chemical MBR membrane modules should be cleaned regularly, online maintenance and cleaning once a week, and cleaning once every 3 months.
