Abstract
An air quality control system scrubs flue gas of SO.sub.2 and particulates with a slurry of lime/limestone and water. The system includes a tank below the contact of gas and slurry in which the chemical action is completed and from which the slurry is recirculated to the scrubber. A bubbler system is connected to the reaction tank to detect the density of the slurry and monitor or control the density. The bubbler system is supplied the liquid and dissolved solids decanted from the thickener to which the slurry is drawn for disposal.
