Abstract: A first filter element has a filter medium body for radial fluid flow therethrough and first and second end plates at opposed end faces of the filter medium body. A first engagement device extending axially parallel to a longitudinal axis of the filter medium body is arranged at the first end plate. A second filter element has a filter medium body and a seal device for radially sealing the second filter element in a filter housing. A fluid flow through the second filter element is perpendicular to a plane spanned by the seal device. The seal device has a second engagement device extending axially perpendicularly to the plane spanned by the seal device. The filter elements are axially joined to a filter element arrangement, wherein the first and second engagement devices engage each other. A filter system has such a filter element arrangement arranged in a filter housing.

Abstract: A solids interceptor and methods of using the same. The solids interceptor includes a tank including an open end, a wastewater inlet, and one or more wastewater outlets. A basket assembly is removably attachable to the tank via the open end between an operable position and a removed position. The basket assembly may seal the open end when in the operable position and expose the open end of the tank to a surrounding environment when in the removed position. A first and second outlet may extend away from an interior of the tank in a first and direction, respectively, with the second direction being oriented at an angle with respect to the first direction. The basket assembly may include a seal that is compressed about a circumferentially extending corner provided on the tank to thereby seal the open end of the tank and the plumbing system.
