Filter housing with built-in filter element

Abstract

This invention provides a filter element for use within a filter housing. As a chemical filter for chemical filtration, it eliminates the need for heating or being heated of the filtered liquid. Even under the same supply pressure as before, it increases the contact probability of adsorbed impurities and foreign matter, exhibits excellent durability, and further improves adsorption efficiency. The filter element (1) for use within a filter housing is composed of one or more stacked groups (2, 3, 4...) of groups of impurity and foreign matter adsorbent materials (2a, 3a, 4a...) disposed on the supply side (F1) and impurity and foreign matter non-adsorbent materials (2b, 3b, 4b...) disposed on the discharge side (F2). In each group (2, 3, 4...), the flow resistance of the filtered liquid to the non-adsorbent material (2b, 3b, 4b...) is higher than that to the same type of filtered liquid to the adsorbent material (2a, 3a, 4a...).
