MBR membrane module using notice


The MBR membrane module is one of the main equipments in today's wastewater treatment. What inspection preparations should we do before we run it?



Check and set


 A. First of all, we must confirm the correct connection of the sewage pipe and the air pipe (the connection error is corrected in time);


 B. Confirm that the MBR membrane module has been firmly fixed on the aeration tank;


 C. Confirm that the reaction cell installed in the MBR membrane module has been cleaned to avoid a certain degree of damage to the membrane module caused by dust, dirt, etc.


 D. Open the air discharge valve before putting the clean water into the reaction tank, so that the air in the MBR membrane module is completely discharged;


 E. Put the water or tap water to be treated to the normal water level;


 F. After the waterproofing is completed, the air discharge valve can be closed.



Introduction to clean water operation

 A. After the aeration blower is started, confirm the aeration amount and the uniformity of the aeration. Note that foam may appear when the water is running. The foam may be caused by the infusible hydrophilic substance in the MBR membrane module.


 B. If a blower is used to supply air to multiple MBR membrane modules, we must ensure that the amount of air obtained by each membrane module is exactly the same. If the difference in air delivery volume is large, please carefully check the structure of the pipeline and the air supply to keep the air supply consistent;


 C. When the water is commissioned and run, check the performance of the control equipment to see if the performance has reached the pre-design effect (discover the problem and deal with it in time);


 D. When carrying out clean water debugging, it is necessary to accurately measure the amount of filtered water, such as the maximum and minimum flow rates, and record the pressure difference between the membrane and the water temperature;


 E. Stop the aeration and filtration operations immediately after the clean water is commissioned.
