ABSTRACT:
A laminated modular water filter includes superposed annular plates. A filter unit is disposed between each adjacent pair of the annular plates. The annular plates include a top plate, a bottom plate, a plurality of intermediate plates, and at least one flow-guiding plate sandwiched between two of the intermediate plates. Each of the top plate, the intermediate plates, and the bottom plate has an annular outer passage unit in fluid communication with a curved outer passage unit in the flow-guiding plate. Dirty water is introduced into two side openings in the top plate, and flows into central holes in the annular plates via the filter units so as to form filtered water. Solid particles in the dirty water are guided into two side openings in the bottom plate via the annular outer passage units and the curved outer passage unit.
