Circular filtering disc and filter device having the same

Abstract

A circular filtering disc and a filter device having the filtering disc. The filtering disc includes a circular partition plate having an inner hub and an outer rim, with radial inlet holes formed in the outer rim and introducing water to the partition plate, and a vertical outlet hole formed in the center of the inner hub and discharging pure water; and a filter fabric placed on or below the partition plate, wherein water supplied to the filtering disc passes through the filter fabric and becomes concentrated at the vertical outlet hole, and is discharged from the filtering disc through the vertical outlet hole. In the filter device, raw water is supplied through the circumferential edges of the circular filtering discs stacked on top of one another in the filter device and is filtered prior to being discharged from the filter device through the center of the filtering discs.
