• B01D 46/68 by means acting on the cake side involving movement with regard to the filter elements
• B01D 46/69 by means acting on the cake side without movement with respect to the filter elements, e.g. fixed nozzles
• B01D 46/70 by acting counter-currently on the filtering surface, e.g. by flushing on the non-cake side of the filter
• B01D 46/74 by forces created by movement of the filter element
• B01D 46/785
• B01D 46/79 by liquid process
• B01D 46/80 Chemical processes for the removal of the retained particles, e.g. by burning
• B01D 46/86 Cleaning the filter surface by interrupting suction so that the filter cake falls by gravity
