Abstract: A filter candle to separate contaminants from a plastic melt is disclosed. The filter candle has a filter element through which a melt flow is directed to retain contaminants contained in the melt flow, and a supporting body to support the filter element. The supporting body is a hollow body having multiple passages for the melt flow. At least one additional supporting body is on the side of said filter element that faces away from the supporting body. The additional supporting body acts on surface regions of the filter element and/or accommodates them such that the filter element can be backwashable.

Abstract: A filter medium for removing particles from a fluid flow has a pre-filter layer and a fine-filter layer joined to each other in the flow direction. A first supporting layer is attached to the unfiltered side of the pre-filter layer and a second supporting layer is attached to the filtered side of the fine-filter layer in order to absorb the longitudinal and transverse forces in the event of tensile loading. The traverse force absorbing layer has a greater bending stiffness in a traverse direction while the longitudinal force absorbing layer has a greater bending stiffness in a longitudinal direction.

Abstract: Fluid treatment elements substantially inhibit electrical charge imbalances and/or build-ups of electrical charges. A fluid treatment element may comprise a multilayer composite including an electrically conductive fibrous matrix, having an upstream side and a downstream side, disposed on a porous substrate, also having an upstream side and a downstream side, which supports the fibrous matrix. The fibrous matrix may include a combination of conductive and nonconductive fibers, wherein the conductive fibers include metal, carbon, or conductive polymer fibers and substantially inhibit an electrical charge and/or build-up of electrical charge. The conductive fibers of the electrically conductive fibrous matrix may comprise less than about 50% by weight of the conductive and nonconductive fibers and may have diameters in the range from about 1 μm or less to about 10 μm. The multilayer composite may also include a drainage layer positioned along one of the upstream side of the fibrous matrix and the downstream side of the porous substrate.
