摘要： There is disclosed a method of treating water comprising adding to the water a composition comprising a weighting agent and an electrolyte having a multivalent metal cation.
The resultant floc absorbs suspended solids in the water and gives rise to a dense sludge which is easily removed from the purified supernatant liquor. A composition for use in the method is also disclosed. The composition may be in the form of a slurry or a friable solid (which may be briquetted).
