In general, the cleaning methods of MBR membrane components include airflow exposure, chemical cleaning, physical cleaning, electrical cleaning and ultrasonic cleaning. First, the flow of air exposure method is the first diehard membrane surface layer of sludge. Therefore, the first treatment method we recommend is to aerate the MBR membrane module through the airflow aeration method. The simple explanation is that it takes two to three hours to aerate the MBR membrane module with the flow condition of the membrane frame.
