Apparatus for cleaning algae and debris from a water treatment tank

Abstract

An apparatus is provided for cleaning algae and other debris from the baffle, weir, spillway and clean water flow channel of a water treatment tank. The apparatus includes a main frame member that is mounted to a revolving skimmer blade assembly of the tank. A series of cleaners, such as brushes, are mounted to the frame member and biased into engagement with the baffle, weir, spillway and walls of the clean water flow channel. In the preferred embodiment, three sets of brushes are provided. A first set of brushes cleans the baffle and weir. A second set of brushes also cleans the weir and additionally the spillway. A third set of brushes includes opposing brushes for cleaning the sidewalls of the clean water flow channel and a brush at a distal end of a support arm for cleaning a bottom wall of the channel. A bridging device is positioned in the clean water outlet of the flow channel so as to support the third set of brushes as it passes over the outlet.
