This document specifies a method for the comparative evaluation of the performances of flocculants for clarification, thickening and sedimentation applications on a given slurry. This performance can be evaluated by
-
the settling velocity in the initial period,
-
the sediment volume after compaction and consolidation, and
-
the clarity of the supernatant liquid.
