Abstract: An incised surface is formed in one surface of a suction plate on the basis of a slit and a pattern roller is placed in a room, which is provided at a thickness part of the slit in which the incised surface is formed, to rotate in place so that the pattern roller partially protrudes outward from the incised surface and forms patterns on a surface of fleeces which are backwashed while passing through the slit so as to increase a filtration area of the fleeces. The backwash may be performed and the filtration area of the fleeces may be increased using the room. The spline-shaped patterns including splines cut to a certain length, patterns including several annular protrusions formed on an outer circumference of the pattern roller, spline-shaped patterns formed on the outer circumference, lattice-shaped patterns, and the like may be formed on a surface of the pattern roller.

Abstract: Disclosed herein is a filtering apparatus for treating ballast water. The apparatus is constructed so that a housing cover plate and an exhaust unit are removably coupled to each other at an upper position of a housing. The exhaust unit includes a base flange on a portion thereof coupled to the housing cover plate and the base flange includes a projecting step that projects to be inserted into a core through hole formed in the housing cover plate. A core serving as a discharge passage of foreign substances includes a shaft coupling unit on a portion thereof coupled to the driving shaft, and is coupled at the shaft coupling unit to the driving shaft via a coupling structure. The outer diameters of the coupling structure and the shaft coupling unit are formed to be smaller than the outer diameter of the core.

Abstract: A device for filtering for treating ballast water and more particularly, to a multicage-type device for filtering ballast water to prevent back pressure, wherein the multicage-type device for filtering ballast water includes a back pressure prevention tank on a backwash line for backwashing and discharging foreign substances that are inside a filter of the device for filtering, so that backwash water and the foreign substances in the backwash line are preliminarily stored in the back pressure prevention tank thereby preventing increase of back pressure, prevents increase of the back pressure on the backwash line by always maintaining level of water inside the back pressure prevention tank at lower than an inlet port that is connected to the backwash line, and always maintains the level of water at lower than a specific level by artificially discharging the backwash water that is stored inside the tank.

Abstract: A fluid pressure vessel has a filter cartridge with spaced headers positioning cylindrical pleated filter media. The headers form an inlet chamber communicating with the inlet upstream side of the filter media and an isolated outlet chamber communicating with the downstream side of the filter media. A hollow piston with a toothed periphery having a circumferential slot is positioned closely adjacent the upstream side of the filter media. The piston hollow communicates with a drain chamber isolated from the inlet and outlet chambers. Upon opening of the drain chamber to atmospheric pressure, the pressure in the piston hollow and slot causes a lower pressure in a localized area of the media and back flushing of trapped material on the upstream side of the media to the drain chamber. An actuator is connected to selectively progressively move the piston and slot along the entire surface of the media.
