Aquaculture filtration system employing a rotating drum filter

Year	Description
1994	Invention patented by James E. Bradley and Duane C. Leach on June 31th, 1994. Abstract: An aquaculture system is provided for filtering water and includes a filter rotatably carried in a container for receiving water to be filtered. The filter includes a porous resilient filter screen forming an outer layer of the filter for removing particulate from water passing through the filter screen. A vacuum cleaning device is positioned in direct contact with the resilient filter screen for removing particulate collected at the outer surface of the resilient filter screen. A water nozzle supplies a stream of water to the resilient filter screen to remove particulate therefrom not previously removed by the vacuum cleaning device. A rotation device is coupled to the filter to rotate the filter in the container.
