Flocculation temperature
Meanwhile, flocculation is a mixing technique that promotes agglomeration and assists in the settling of particles. The most common used coagulant is alum, Al 2 (SO 4) 3 ·14H 2 O. The chemical reaction involved: Al 2 (SO 4) 3 · 14 H 2 O → 2 Al (OH) 3(s) + 6 H + + 3 SO2− 4 + 8 H 2 O See more Flocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from See more According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters".

Usually in higher pH ranges in addition to low ionic strength of solutions and domination of monovalent metal See more WebThe flocculation efficiency of cationic flocculant is influenced by the reaction temperature. The best reaction conditions are: reaction time of 3 min, reaction temperature of 70°C, ratio of lignin to quaternary ammonium salt of 1:2.5, and stirring rate of 600 r/min.
