ABSTRACT:
In a water purification apparatus in which a granular filter medium is washed by agitation imparted to the filter medium, a pipe adapted for collection of purified water is mounted within the heap of precipitated granular filter medium and enclosed by a filter mesh to prevent outflow of the filter medium. Sliding contact elements such as turns of a wire wound about the collecting pipe or linear brush-like members inserted on the collecting pipe are also provided between the pipe and the filter mesh so that both the inner and outer surfaces of the filter mesh may be cleaned during countercurrent washing of the filter medium for assuring optimum water permeation at all times.
