Supernatant turbidity and sludge volume in a flocculation process with concomitant use of inorganic and polymer flocculants
Flocculation is a typical process which does not progress stoichiometrically. Reproducibility of flocculation with polymer flocculant depends strongly on the amount of additive, the manner of addition and the mixing intensity. It has been found that a dry powder flocculant mixture composed of...

| description | Flocculation is a typical process which does not
progress stoichiometrically. Reproducibility of
flocculation with polymer flocculant depends
strongly on the amount of additive, the manner of
addition and the mixing intensity. It has been found
that a dry powder flocculant mixture composed of
inorganic flocculant, polymer flocculant and
flocculation aid shows high reproducibility of
turbidity removal as long as it contains an adequate
amount of flocculation aid. The flocculation aid
helps the dispersion of the polymer powder into a
suspension [1]. Previously, we have reported that the
optimum dosage of inorganic flocculant under a
given dosage of polymer flocculant decreases as the
polymer dosage decreases, and proposed a procedure
for determining the optimum composition of a
composite dry powder flocculant for turbidity
removal [2]. In this study, the procedure is examined
by using polymer flocculants of various molecular
weights and charge densities. Effects of flocculant
dosage on sediment volume and supernatant turbidity
are also examined. |
