We need to check and follow up the treatment and cleaning of the ultrafiltration system every day. If abnormal conditions are found, we must take corresponding measures to solve them in a timely manner, and we must maintain a daily record of the situation. During this period, we may find that there is a decrease in the amount of transmission. If the amount of transmission decreases by 30, we must pay attention to it. At this time, general organizational cleanup measures will be taken.
Therefore, cleaning is the work to maintain ultrafiltration equipment, and the surface of the equipment will often adsorb a large amount of impurities such as microorganisms and particulates during the work. At this time, cleaning can not only clean the equipment, but also extend the service life of the equipment. When the equipment is running, we can use reverse hydraulics for regular backwashing to clean up the impurities adsorbed or intercepted during the work on the surface of the ultrafiltration membrane, and reasonably adjust the system operation time and cleaning time according to the water inflow.
During the maintenance work on holidays, during short-term holidays, the equipment must be guaranteed to run 24 hours, and traffic monitoring should be done in a timely manner. For long-term holidays, it is necessary to use ultrafiltration to squeeze out the paint solution in the membrane tube. Use the ultrafiltration to clean the entire ultrafiltration membrane group. The cleaning time is controlled to about 12 hours. When the ultrafiltration system is stopped, the ultrafiltration membrane should be cleaned in time. The group was sealed with ultrafiltration water to ensure that the membrane surface was moist.
