Abstract

A method of transferring filter media between a media bed of a dry scrubber and a filter media container, comprising placing the media bed in flow communication with the filter media container, obstructing a majority of an airflow path of the media bed, the airflow path extending from an unfiltered air input opening of the dry scrubber, through the media bed of the dry bed scrubber, to a filtered air output opening of said dry bed scrubber, powering a blower in the airflow path of the media bed when the airflow path is obstructed and the media bed is in flow communication with the filter media container, whereby the filter media is transferred between the media bed and the filter media container.
