Abstract
A filter system and associated methods of filtering utilize a combination of ultrasonically enhanced backwashing and a modified filter media configurations for increasing the specific loading on a portion of the filter media, thereby tending to increase the total particulate holding capacity of the improved filter. Depending on factors such as the filter configuration, the particulate size distribution and the differential pressure that can be maintained across the filter, it is expected that the particulate holding capacity can be more than doubled relative to a conventional filter having similarly configured filter media.
