Abstract
The present invention is a highly efficient and easily shippable drum filter device comprising segmented filter media, easy to manufacture light-weight drum segments or torsional tensioning elements. Preferably, it comprises bulged side wall, that can be fitted after shipment and that can be readily opened for easy access to the filter. The drum filter device can be incorporated into a filtering system further.
