Micro porous filter is a new type of filtration equipment developed domestically and internationally. It can filter out particles and bacteria above 0.1um in liquids and gases. It has the advantages of high filtration accuracy, fast transition speed, minimal adsorption, no medium detachment, acid and alkali corrosion resistance, and easy operation. It is now widely used as an essential equipment in industries such as pharmaceuticals, chemicals, electronics, beverages, fruit wine, biochemical water treatment, and environmental protection.

Micro porous filters are now widely used as essential equipment in industries such as pharmaceuticals, chemicals, electronics, beverages, fruit wine, biochemical water treatment, and environmental protection. So its maintenance is very necessary, not only to improve the filtration accuracy, but also to extend the service life of the microporous filter. How can we do a good job of maintaining the microporous filter?

There are two types of maintenance for microporous filters, namely precision microporous filters and coarse microporous filters.

1. Micro porous filter for coarse filtration

① The core part of the microporous filter for coarse filtration is the filter core, which is composed of a filter frame and stainless steel wire mesh. The stainless steel wire mesh is a vulnerable component and requires special protection.

② After the filter has been working for a period of time, a certain amount of impurities settle in the filter core. At this time, the pressure drop increases and the flow rate decreases. It is necessary to remove the impurities in the filter core in a timely manner.

③ When cleaning impurities, special attention should be paid to ensure that the stainless steel wire mesh on the filter element is not deformed or damaged. Otherwise, if the filter is installed again, the purity of the filtered medium will not meet the design requirements, and equipment such as compressors, pumps, and instruments will be damaged.

④ If the stainless steel wire mesh is found to be deformed or damaged, it needs to be replaced immediately.

The microporous filter has high filtration accuracy, fast transition speed, low adsorption, no medium detachment, acid and alkali corrosion resistance, easy operation, and a wide range of applications. Its role is becoming increasingly important.

2. Precision microporous filter

① The core part of a precision microporous filter is the filter element, which is composed of special materials and is a consumable component that requires special protection.

② After the precision microporous filter works for a period of time, the filter element blocks a certain amount of impurities. At this time, the pressure drop increases and the flow rate decreases. It is necessary to remove the impurities in the filter in a timely manner and clean the filter element.

③ When removing impurities, special attention should be paid to the precision filter element, which must not be deformed or damaged. Otherwise, if the filter element is installed again, the purity of the filtered medium will not meet the design requirements.

④ Some precision filters cannot be reused multiple times, such as bag filters, polypropylene filters, etc.

⑤ If the filter element is found to be deformed or damaged, it needs to be replaced immediately.
