Abstract

A dynamic vertical solids separator acts as a dynamic filter to produce a clarified supernate sample for use in measuring the net electrokinetic charge demand of finely divided particles suspended in the slurry. The dynamic vertical solids separator first removes silt by simple solids separation, and then promotes rapid agglomeration of particles by first directing the slurry across serrated floc plates and then discharging the slurry upward through a venturi. Above the venturi a dynamic sample pool forms, within which the clarifying action occurs. The clarified supernate forms above the sample pool with a visible boundary separating the two. The clarified supernate can be fed to a streaming current detector for measuring the net electrokinetic charge demand of finely divided particles suspended in the slurry, or the position of the boundary can be measured as an indication of the concentration of finely divided particles suspended in the slurry. The measure of the net electrokinetic charge demand of finely divided particles suspended in the slurry can then be used in an automatic control system to control the turbidity of the slurry.
