Secondly, cleaning is the work that must be done to maintain the ultrafiltration membrane separation equipment. In the process of working, the surface of the equipment often absorbs a large number of microorganisms, particulate matters and other impurities. At this time, cleaning can not only clean the equipment, but also extend the service life of the equipment.
During the operation of the equipment, we can use reverse hydraulic to carry out backwashing regularly, clean up impurities that the ultrafiltration membrane surface adsorbs or intercepts in the work, and adjust the operation and cleaning time of the system reasonably according to the water inflow.
Finally, in the holiday maintenance work, in the short holiday, to ensure the equipment 24 hours of operation, timely good flow monitoring.
During the long-term vacation, the paint in the membrane tube should be extruded with ultra-filtrate, and the whole ultrafiltration membrane group should be cleaned with ultra-filtrate. The cleaning time should be controlled to about 12 hours. When the ultrafiltration system stops operation, the ultrafiltration membrane group should be cleaned timely and the ultrafiltrate water seal should be carried out to ensure the membrane surface is moist.
The above contents are the matters needing attention for the daily operation and maintenance of the ultrafiltration membrane separation equipment.
