Abstract

Method for removal of fouling (14) and/or plugging (13) out of a bundle (11) of channels (12) by treatment with a liquid (2), in particular out of firmly interconnected channels (12), oriented in parallel to each other, as a catalyst module, which can be carried out very quickly and cost effectively, by filling the channels (12) repeatedly and alternately with the liquid (2) from their ends, and draining at least part of the filled in liquid off the same ends.
