Abstract
A method for removing matter from a filter is disclosed. The method may include measuring loading conditions of a filter media. The method may also include applying at least one voltage pulse between an electrode external to the filter media and a housing of the filter media to induce a plurality of shock waves directed toward the filter media, based on the loading conditions.

A method for removing matter from a filter, comprising:
- measuring loading conditions of a filter media;
- and
- based on the loading conditions, applying at least one voltage pulse between an electrode external to the filter media and a housing of the filter media to induce a plurality of shock waves directed toward the filter media.
A regeneration system comprising:
- a filter media configured to collect matter from an exhaust flow;
- a conductive housing enclosing the filter media;
- a diagnostic device configured to monitor loading conditions of the filter media;
- an electrode disposed within the conductive housing separate from the filter media and electrically insulated from the conductive housing;
- a pulse generator configured to apply a voltage pulse between the electrode and the conductive housing such that a plurality of shock waves are created within the conductive housing;
- and
- a regeneration controller in communication with the pulse generator and the diagnostic device, and being configured to activate the pulse generator based on the loading conditions.
