<p>A filter apparatus comprises a plurality of ceramic porous filter elements (l) each having parallel passages separated by filtering walls, with the passages closed at either the inlet side (4) or the outlet side (6) to form inlet and outlet passages respectively. The elements are in individual casings (l5) piled one above the other with the filter elements (l) being spaced apart from each other. Raw liquid to be filtered is supplied to the inlet sides (4) of the filter elements via supply chambers (36) located between the filter elements. Filtrate discharge chambers (37) are located between the filter elements for receiving filtrate which has passed through the filter elements. With this arrangement, raw liquid passages and filtrate passages are completely separated, so that no mixture of the raw liquid and the filtrate occurs, and therefore filtering can be effected with high efficiency and high reliability. The apparatus can be light in weight.</p> |
