Conclusions
The coagulating action of aluminum sulfate and of the combination of it with polyacrylamide on a suspension of chamotte and clay, leading to a significant increase in particle size of the dispersed phase, was investigated.
The presence of a threshold value of the addition of coagulant as an important production parameter determining the unstable suspension type sedimentation of particles was shown.
To disturb the stability of the systems and to accelerate the clarification process of waste waters contaminated with chamotte and clay the necessary additions of reagents are 25–50 mg/liter of aluminum sulfate and 5 mg/liter of polyacrylamide.
