Treatment of Mount St. Helens volcanic ash suspensions by plain sedimentation, coagulation, and flocculation
Aqueous suspensions made from Mount St. Helens volcanic ash, which fell in Pullman, Wash., on May 18,1980, were characterized in terms of pH, conductivity, alkalinity, acidity, turbidity, settleable solids, and fluoride content. Plain sedimentation followed by coagulation‐flocculation successfully reduced the turbidity and fluoride content of the ash suspensions at two alkalinity concentrations and two volcanic ash levels.
