摘要： There is a need to reduce the amount of overlapping parts of a nonwoven fabric of a filter component to thereby lengthen the life of the filter component. This need is met by the filter component formed of a cylindrical nonwoven fabric having a center axis, and having a plurality of polygon-shaped cross-sections which are a same shape that are formed side-by-side at predetermined intervals along the center axis. Each side of each of the polygons is formed by a mountain fold part on a plane perpendicular to the center axis, and each vertex of one polygon is connected by a mountain fold part to each vertex of another polygon, respectively.

摘要： A filter designed in compact form and requiring low filtration cost, by which there is no need to replace filter each time it becomes clogged and for which no liquid for backwashing is required, and with which is possible to filter under liquid pressure. In the filter, two ends of a filtering segment with a predetermined length of a filter medium in an oblong tube shape are movably and closely squeezed and held by a pair of opposing pressure rollers. A raw liquid introducing pipe is closely squeezed and held between a pair of pressure rollers, a forward end of the raw liquid introducing pipe is disposed within the range of the filtering segment of the tube-like filter medium. The filter medium is moved to the filtering segment constantly or when the filter medium is clogged, and the clogged filter medium is moved beyond the range of the filtering segment.
