Abstract

The present invention relates to a zigzag-type fiber filter and to a filtering apparatus using the zigzag-type fiber filter, which can efficiently and smoothly transition between a filtering process and a backwash process without malfunctioning, even when the transitioning between said processes is periodically and continuously performed, can reduce manufacturing costs as a strainer is not required as an inner component, and can automate the control of the pores of the fiber filter material forming a filter layer.

IPC Classes  ?

• B01D 33/052 - Filters with filtering elements which move during the filtering operation with filtering bands or the like supported on cylinders which are pervious for filtering with endless filtering bands combined with a compression device
• B01D 29/11 - Filters with filtering elements stationary during filtration, e.g. pressure or suction filters, not covered by groups Filtering elements therefor with bag, cage, hose, tube, sleeve or like filtering elements
• B01D 35/16 - Cleaning-out devices
