ABSTRACT:
A water purification device includes a plurality of tiers of flow channel or passage defining plates along the inner surface of the wall of a filter tank, a water collecting strainer at about the center of the tank for collecting purified water, and raw water distribution conduit means for distributing and supplying raw water to the respective flow channels. Since raw water permeates into the filter layer in the tank not only from above but from below and from the peripheral zone of the tank, and the purified water is collected at the center and drawn to the outside, the filtration efficiency is improved as compared to the case where raw water is permeated into the filter medium from above and the purified water is collected at the bottom of the tank.
