Suspension

TL;DR: Sure, here is the TLDR: Maximum flocculation occurs at a certain positive zeta potential, and persists until the zeta potential becomes sufficiently negative for deflocculation to occur.

Abstract: examination of the various suspensions shows that at a certain positive zeta potential, maximum flocculation occurs and will persist until the zeta potential has become sufficiently negative for deflocculation to occur once again. The onset of flocculation coincides with the maximum sedimentation volume determined. F remains reasonably constant while flocculation persists, and only when the zeta potential becomes sufficiently negative to effect deflocculation.
