Do high-efficiency filters need regular cleaning? What is the working principle of high efficiency filter?

High Efficiency FilterDoes it need to be cleaned regularly?High Efficiency FilterHow does it work?

Does the high-efficiency filter need to be cleaned regularly? The answer is that it needs to be, because the high-efficiency filtration material is mainly glass fiber paper or PP material, and the filtration efficiency can reach 90%-99.999% (0.3um). Due to its own high filtration precision for dust particles, the requirements for the filter paper are also high, and it cannot be damaged in any way, therefore, in the cleanliness industry, the high-efficiency filter is not easy to clean.

If you want to clean it, of course, it is not clean, not to mention that after washing, the whole filter has been broken badly, and then talk about using it once again! How to clean it?

It is hereby recommended that the majority of users should not only consider how to clean the filter, but should focus on how to extend the service life of the filter itself. So as to better utilize the performance of high-efficiency filters, in fact, want to do this is not difficult, as long as the following two points of attention:

1. In the foreground air conditioning fresh air unit, the primary effect filter maintenance, because the primary effect filter itself cost higher, but also appropriate cleaning, strict compliance with the primary effect filter replacement norms, generally a change in March, the intermediate effect filter in June, the intermediate effect filter in June, a change, the specific replacement is still to be based on the site conditions to judge.

2. To regularly clean the new air ducts, for example, the first replacement of high-efficiency filters, air supply ducts can be cleaned up along with the replacement of high-efficiency filters can reduce the burden!

Of course, even if you don't need to clean your HEPA filters, there are other ways to extend their service life and reduce the cost of HEPA filter replacement!

How do high efficiency filters work?

Mechanical filtration of wastewater treatment is commonly used in many ways, and according to different filter media, mechanical filtration equipment is usually divided into two categories: granular media filtration and fiber filtration.

One of the granular media filter is mainly used sand and other particles filter as a filtration medium, and then through the interception and filtration of solid suspended solids in the water. There are advantages and disadvantages, the disadvantage is that the filtration speed is slow. Usually not more than 7m/h. In addition to the small amount, the core filter layer is only the surface of the filter layer.

However, high efficiency asymmetric fiber filtration systems primarily use asymmetric fiber bundle materials as filters. This type of filter is a kind of fiber that is not being symmetrical, but can add nuclei on the basis of fiber bundle filter, which not only provides the advantages of fiber filter, but also provides the advantages of particle filter. Due to the special structure of the filter, the filtration gap can quickly form a gradient density, so that the filter is fast, fouled, easy to backwash, through a special design, pharmaceuticals, mixing, flocculation, filtration process, the use of the filter this equipment can effectively remove the organic matter in the aquaculture water, and to reduce the COD, ammonia nitrogen, nitrites and so on.
