In case of anionic polyelectrolyte, it was observed that the optimum flocculant dose depends on the amount of cations present in the system. For suspensions made with demi-water, a lower optimum flocculant dose (<1 mg/g) than for suspensions prepared in tap water (2.28 mg/g) was observed.

Article Flocculation of Clay Suspensions by Anionic

The optimum flocculant to clay ratio was defined as the ratio that gives the fastest initial floc growth by static light scattering or fastest initial settling velocity by settling column experiments. In case of anionic polyelectrolyte, it was observed that the optimum flocculant dose depends on the amount of cations present in the system.

How to Select a Chemical Coagulant and Flocculant.

organic polyelectrolyte should not be considered. The choice of inorganic coagulant should be one that quickly generates the Al(OH)3 sweep floc and will form a stable sludge bed. In moderate turbidity waters (<100 NTU) the use of a general purpose inorganic salt is preferred, and most will be successful if the other conditions are right.
