Abstract: A water-treating ceramic filter unit comprising a filter having pluralities of flow paths partitioned by porous ceramic cell walls and plugs alternately sealing the one-side or other-side ends of the flow paths; a housing containing the filter such that water to be treated is supplied from one end of the filter, and that the treated water is discharged from the other end of the filter; and seal members disposed on the outer edge portions of both end surfaces of the filter for longitudinally sandwiching and fixing the filter to the housing; the maximum of a gap between a side surface of the filter and the housing being equal to or less than the equivalent diameter of the flow paths.

Abstract: A water-treating ceramic filter module comprising a filter unit, and a housing containing the filter unit; the filter unit comprising pluralities of cylindrical honeycomb structures each having pluralities of flow paths partitioned by porous ceramic cell walls and extending in one direction, and sheet-shaped connecting members connecting the honeycomb structures in series in the flow path direction; each connecting member having pluralities of penetrating holes for achieving the communication of the corresponding flow paths of adjacent honeycomb structures, to constitute pluralities of communicating flow paths; the communicating flow paths being composed of first communicating flow paths plugged only at one-side end, and second communicating flow paths plugged only at the other-side end; and the housing has an inlet on the side of the one-side end for receiving the water to be treated from outside, and an outlet on the side of the other-side end for discharging the treated water.
