Installation of bag filter in series can realize the filtration gradually.
If gradual filtration is used as the pre-filtration of high precision filtration, the cost of filtration will be reduced a lot.
Also, we can combine sand filtration and other filtration method with bag filter together, to improve the filtration efficiency and reduce the filtration cost.
Combine self cleaning machine, centrifugal filter and bag filter together. We can use it separately, and also can install this with other filters in series, to get best result.
