CaCl2 is used in Mexico in an industrial wwtp application for sludge conditioning that we wish to mimic in another country; we toured the plant and saw it first-hand.
We had never heard of using CaCl2 either.
Does anybody have any experience or knowledge of the use of calcium chloride for sludge conditioning just prior to mechanical dewatering? I'm curious to know exactly what it does, how it does it, who does it, and if it is a good idea.
Thanks!
