Final Jeopardy
Coagulant Aids
Final JeopardyWhat is a coagulant
aid and what are three types of coagulant
aids??
Final Jeopardy-Answer• They are Activated silica, weighting
agents like bentonite clay, and polyelectrolytes.
• Stronger more settable flocs• Overcome the effect of temp drops that
slow coagulation• Reduce the amount of coagulant needed• Reduce the amount of sludge produced.
