The foregoing has outlined rather broadly the features and technical advantages of the present invention in order to better understand the claims of the invention which will be described later. Additional features and advantages constituting the claims of the present invention will be described below. It should be appreciated by those skilled in the art that the conception and specific embodiments of the invention disclosed may be readily used as a basis for designing or modifying other structures for carrying out similar purposes to the invention.

In addition, the inventive concepts and embodiments disclosed herein may be used by those skilled in the art as a basis for modifying or designing other structures for carrying out the same purposes of the present invention.

As described above, the cartridge type multilayer fiber filtration apparatus of the present invention sequentially processes the compressed fiber layers 28, 30, and 32 in which the inflow water is used as a medium at the uppermost part of the main body 18. By passing through to ensure that the suspended solids to be removed from the fiber layer having the optimum density, thickness and properties, respectively, can maximize the filtration efficiency. In other words, depending on the degree of contamination of the raw water, the nature of the suspended solids, and the target water quality of the treated water, the top fiber layer 28 is designed to filter out relatively large particles and the lower fiber layers 30 and 32 to filter out small particles. Substantial multi-layer filtration can be realized by separating.

In addition, by configuring the filter medium fiber layers 28, 30, 32 and the fiber fixing plate 34 in the form of a cartridge, there is an advantage that the installation of the device, the replacement and filling of the filter medium can be simplified.

In the backwashing process, the fiber is sufficiently relaxed by using a mechanical device 20 for compressing or relaxing the fiber such as a pneumatic cylinder, a spur gear, and the like. Inflow from the lower portion 22 has the advantage that the backwash can be performed completely.
