Cast Steel Filter 2

Test bed filters:

For the filter performance test-bed, the test-bed must be strictly purified before the test, so the test system and the pollution injection system serving the test system need to be equipped with filters. In this case, the filter and the tested filter are two different things. Its accuracy requirement and the contamination capacity requirement are higher than the tested filter accuracy, in order to distinguish the same test system. The two types of filters are called test bed filters and the tested filters are called test bed filters.

In fact, there are many kinds of filters, such as laminated filter, sand filter, carbon filter and so on. The main principle is to use the pore size of the filter media to intercept materials smaller than the pore size of the medium. Of course, some filter media also have adsorption and other special effects. Most filter backwashing is not so troublesome, as long as clean water from one end of the filtered water into the media in the reverse backwashing filter can achieve a good backwashing effect.
