    摘要: A filter comprises a main tank and at least two separate beds of particulate filter media contained in respective conical recipients integrated within the main tank so as to minimize the overall height and weight of the filter. A transport pipe is provided for each conical recipient in order to transport dirty filter media therefrom to a washing device in which the dirty filter media is washed as it flows downwardly in counter-current with a wash liquid. A filter media return pipe is provided for each conical recipient in order to return the cleaned filter media therein. The provision of multiple transport pipes and return pipes ensures efficient distribution of the filter media within the filter.
