Abstract

A method of coacting a fluid with a media, such as granular particles. The media is moved to an upper portion in an upright media container, and held there during a treatment cycle in which the fluid is coacted with the media. When the media requires regeneration, the media is allowed to fall to a lower portion of the media container where a regeneration fluid is passed through the media.
