Mathematical modeling of multi-layer filter parameters calculation depending on application field

The process of a sediment formation on a multilayered Alter is considered. The multilayer filters efficiency calculation method is proposed, which helps to ensure maximum dust holding capacity and minimum pressure differential in the diameter and thickness variations of fiber layers. According to the results of double-layer specimens studies the maximum amount of sediment is deposited on filters which packaging density is in the range of 0.03-0.06.
