Embodiment Construction

[0012] Description of the preferred embodiment

[0013] figure 1 is a cross-section of a filtration unit 10 comprising a multiple fused laminate of substrates 12 with active material 14 in layered form. Unit 10 is shown in the form of a cylinder, known in the industry as a cartridge filter. However, it is to be understood that the invention is also applicable to bag filters. Unit 10 has a hollow core 16 . The outermost and innermost layers of the cell 10 are preferably formed only from the substrate so as to coat the active material 14 dispersed or sandwiched between the substrate layers at the center of the cell. Substrate 12 is preferably blown microfibers such as polypropylene fibers. Depending on the intended use of the filter unit, such as irrigation, fertilization, disinfection or cleaning, the active substance 14 can consist of a selected variety of substances. For example for filtering water, the active material may be carbon particles.

Abstract

A blown microfibre filter unit has the laminated fibrous layers and the active matter applied to said laminated layers. The fibrous layers are fused into a whole.

Description

technical field [0001] The present invention relates to a filter unit, which is applied in particular to a microfiber unit of the cartridge or bag type, said cartridge or bag having laminates of fibrous material and an active substance applied between the laminates. Background technique [0002] Filtration units as described in US Patent Nos. 3,816,304, 4,902,427, 5,389,166 and 5,679,251, wherein the active material is internally dispersed in the fibrous material. The blown microfiber material used to manufacture cartridges or filter bag filter units is both economical and highly effective. An example of such a unit is described in US Patent No. 4,983,292, the contents of which are incorporated herein by reference. But so far, there has been no introduction of combining active substances with such blown microfibrous units. The active substance is usually added in the form of a powder or small granules. When the active material is added to the blown microfiber stream, the ...
