A method for operating a filter includes forcibly passing a stream of a fluid through a filter wall of the filter from a raw gas side to a clean gas side of the filter so as to separate out particles and particle constituents from the stream, wherein the particles and particle constituents are collected on the raw gas side and performing a regeneration process on the filter during operation of the filter. The regeneration process includes removing particles and particle constituents from the raw gas side of the filter and moving the removed particle constituents to a receiving device disposed on the raw gas side. Alternatively, the filter walls includes a plurality of channels on the raw gas side, each channel closed by a closure wall configured to be partially opened to enable the disposing of the particle constituents.

The method as recited in claim 2, wherein the fluid is a gas. 7. The method as recited in claim 2, wherein the filter is a particle filter for an internal combustion engine. 8. The method as recited in claim 2, wherein that the fluid stream forcibly passed through the filter so that the particle constituents are carried by the fluid to the receiving device is imparted with a pulsating flow to move the removed particle constituents to the receiving device. 9. The method as recited in claim 2, wherein a portion of the fluid stream flows through the receiving device. 10. The method as recited in claim 2, wherein the receiving device includes a regenerable filter surface. 11. The method as recited in claim 2, wherein the forcibly passing a stream of fluid through the filter so that the particle constituents are carried by the fluid to the receiving device includes a step of passing a medium that moves the removed particle constituents to the receiving device through the receiving device and out of a flow outlet leading out of the receiving device and into the clean gas side. 12. The method as recited in claim 2, wherein the forcibly passing a stream of fluid through the filter so that the particle constituents are carried by the fluid to the receiving device includes closing an outlet leading out of the clean gas side of the filter and passing a medium that moves the removed particle constituents to the receiving device through the receiving device and out of a flow outlet leading out of the receiving device. 13. The method as recited in claim 2, wherein the regeneration process includes feeding nitrogen dioxide into the filter. 14. The method as recited in claim 2, wherein the regeneration process is performed thermally. 15. The method as recited in claim 2, wherein the forcibly passing a stream of fluid through the filter so that the particle constituents are carried by the fluid to the receiving device includes feeding a pressurized medium into the filter on the raw gas side to move the removed particle constituents to the receiving device. 16. The method as recited in claim 15, wherein the pressurized medium is pressurized air. 17. A filter comprising: a filter wall dividing a clean gas side and a raw gas side of the filter and configured to separate out particles and particle constituents from a stream of fluid passing flowing from the raw gas side through the filter wall and to enable the particles to be removed in a regeneration process; anda receiving device located downstream of at least a portion of the filter wall configured to receive a flow of the fluid from the raw gas side of the filter therethrough and to receive and hold the particle constituents, the filter wall and receiving device being arranged such that the stream of fluid passing through the filter wall from the raw gas side forces the particle constituents into the receiving device. 18. The filter as recited in claim 17, wherein the receiving device is removably connectable to the filter wall.
