Abstract
A scrubbing apparatus comprises a gas-exchange column with a flow control system for removing extraneous gaseous matter from water. The flow control system includes an upper reservoir mounted above the column for receiving a supply of water to be passed through the column, a controllable valve responsive to predetermined control signals for regulating the flow of water to the upper reservoir, a level sensor in the upper reservoir responsive to the level of water therein for producing the predetermined control signals for the controllable valve in a predetermined systematic fashion in accordance with the water level, and a further adjustable orifice arrangement for delivering water from the upper reservoir to the column. The gas exchange column preferably comprises a plurality of foraminous sheets mounted in vertical array, each sheet including at least one enlarged through aperture; and the apertures of adjacent sheets in the vertical array being respectively offset.
