Mechanical filters are required in many processes, such as the electrodialysis project we are very familiar with, electrodialysis project, a process that must be passed before water purification is to remove suspended solids, particles and other impurities through mechanical filters. There are also many processes such as desalination of brackish water, production of space water, purified drinking water, defluoridation of groundwater, preparation of injections in the pharmaceutical industry, chemical fertilizers, water in the machinery industry and other processes that require the use of mechanical filters. Precautions for daily operation of mechanical filters: 1. After the system has been shut down for a long time, when the system is restarted, the filter material should be washed for about 5 minutes until the water is clear.
2. When the system is running for the first time or after a long-term shutdown, the equipment should be exhausted: open the exhaust valve, the water inlet valve, and then enter the water until the exhaust valve V8 discharges water without air (some small filters are not separated Set the exhaust valve, and the water outlet can be used for exhaust). 3. For large-scale filters, air scrubbing can be used to enhance the backwashing effect. Generally, compressed air (strength 10-18 l/s.m2) is introduced, and then air-water backwashing is performed. 4. When the equipment is backwashed, the backwashing intensity should be well controlled, and the activated carbon flushing should be prevented from leaking out of the system.
5. According to the quality of influent water, the activated carbon filter material should be replaced regularly, usually every 3-6 months.
