Daily maintenance of PP filters

‌ Daily maintenance of PP filters mainly includes the following aspects:

‌ Regular cleaning and replacement of filter elements: Regular cleaning of the filter is the key. Excessive accumulation of impurities will clog the filter, increase energy consumption, and reduce filtration efficiency. When cleaning, use a suitable cleaning agent to avoid corrosion of the PP material. For dirt that is difficult to clean, a mild chemical soaking method can be used, but it must be rinsed clean afterwards. If the filter element cannot be cleaned or the filtration effect is poor after cleaning, the filter element should be replaced in time.

‌ Check seals and valves: Always check the seals, valves and other vulnerable parts of the filter, and replace them in time if they are worn or aged to avoid losing more than less.

‌ Check pressure and flow: Regularly check the inlet and outlet pressure and flow of the filter. When the pressure difference exceeds the set value or the flow drops significantly, the filter element should be cleaned or replaced in time. At the same time, check whether there is leakage at the connection parts of the filter. Once a leak is found, tighten or replace the seal in time.

‌Check the housing and accessories‌: Clean the filter housing regularly to remove dirt and rust on the surface to prevent corrosion of the housing. For stainless steel housings, use a special cleaning agent to wipe; for carbon steel housings, if rust occurs, remove rust and anti-corrosion treatment should be carried out in time. In addition, regularly check whether the valves, pressure gauges and other accessories of the filter are working properly, and replace them in time if damaged. ‌High-temperature disinfection‌: For occasions where high-temperature disinfection is required, the operation should be carried out in accordance with the requirements of the equipment manual. It is usually necessary to remove the filter element from the plastic bag and place it in a disinfection cabinet for high-temperature disinfection. ‌Through the above maintenance measures, the service life of the PP filter can be effectively extended, its stable operation can be ensured, and the filtering effect can be improved.
