ABSTRACT:
A cylindrical element for filtering various substances and separating particles therefrom is shown wherein a wire is cylindrically wound in the form of a helix to form a helical slit between the adjoining peripheral margins of the wire thereby increasing to the maximum the area for filtering or separation treatment. The helical slit forms a linear treatment hole with improved filtering and separation deficiency. The cylindrically wound wire may be supported by actually extending support members having grooves therein or by cylindrically-shaped support members having openings of various sizes and shapes. An embodiment of the invention wherein the cylindrical element is mounted in a pipe is also shown.
