The clarification of humic‐acid suspensions by means of coagulation followed by sedimentation and by microflotation has been studied as a function of sol concentration, pH, sol stability, coagulant concentration, and ionic composition. Microflotation produced the same degree of removal as coagulation‐sedimentation but at a much faster rate.
