Tablets at 8% weight gain made it through the ... talc as traditional anti-adherent agent, which causes sedimentation and system instability. These
middle Miocene; this sedimentation was accompanied by basaltic in- trusions, with moderate alteration under closed conditions (smectite, sometimes chlorite and talc).
The talc particles ballast the flocs of bacteria and accelerate their sedimentation. The addition of talc results in top quality discharge and zero bacterial loss. It can help to upgrade plants without resorting to costly plant expansions.
In the case of the HSA talc the falling leaf effect for very fine platelets perturbed the aspect ratio values for all models that base on the sedimentation technique. The current model underestimates the aspect ratio, if the particles are too fine whereas the models of Jennings and Parslow, 1988, Pabst and Berthold, 2007 overestimate the ...
