Abstract
The present invention is directed toward the dampening of concentration variations in fluid streams, especially concentration variations that are substantially sinusoidal, by subjecting such streams to a plurality of backmixing steps whereby such concentration variations are reduced. In one embodiment of the present invention, there is provided a surge drum that is divided into a predetermined number of mixing stages, each of which is provided with means to create a fluid jet stream at substantially the inlet of the mixing stage and baffle means positioned with respect to the inlet jet for reversing the flow of the jet.
