Abstract: A filter for water treatment exhibiting high filtering capability by preventing vortices, and a filter apparatus including same is provided. The filter for water treatment, which is a cross flow type filter, includes a metal thin plate and a plurality of micropores passing through the metal thin plate so as to filter water flowing on one side of the metal thin plate. A micropore includes an inlet port which is formed on one surface of the metal thin plate and through which water flows in; a discharge port which is formed on the other surface positioned opposite from the one surface of the metal thin plate, and through which the water flowing in through the inlet port is discharged; and a curved portion convexly curved towards the inside of the micropore connects the inlet port and the discharge port. The curved portion and the other surface form a singular surface.

Abstract: The present invention relates to a filter assembly in which a filter, having a plurality of micropores i.e. openings, which are open in a thickness direction thereof in a state of being extended horizontally or inclinedly with respect to a flow direction of a fluid containing solid foreign substances and have a tapered shape gradually narrowing from upstream ends to downstream ends thereof, is installed communicatively with an upstream end of a branch pipe interposed in a portion of a flow pipe through which the fluid containing the solid foreign substances flows so as to form, in conjunction with the flow pipe, a filtered flow path which passes through the filter and an unfiltered flow path which does not pass through the filter. Therefore, the problem can be solved.

Abstract: The present invention relates to: an improved metal filter having a plurality of apertures which are micropores having a taper shape by which the diameters thereof become narrower from an upstream end towards a downstream end in a state where the directions of the apertures are perpendicular to, or are at an acute angle with respect to the flowing direction of a fluid containing solid foreign substances; and a permanent filter assembly having a filtering pipe connected, in the form of a pitot tube, part-way along a flow pipe in which the fluid containing foreign substances flows, and having the improved metal filter communicatably mounted on the upstream end of the filtering pipe.
