ABSTRACT:
A coal-fired power plant with a wet scrubber wherein sulfite or bisulfite ions are converted to sulfate ions by forced aeration in the scrubber reaction tank. Air bubbles are introduced at only a few points in the tank, but an impeller is used which continually sweeps fine particulates off the tank bottom until they have reached a certain minimum size.
