In engineering, the flocculation process is generally divided into a mixing process section and a reaction flocculation process section. A mixing process section: the medicament is fully contacted and mixed with the raw water body; a reaction flocculation process section: the reaction stage is the process of reacting the added medicament with small suspended matters and colloid chroma in the raw water body of the floc to form floc particles.

Secondly, when the flocculator is installed, the thin steel wires need to be manually crossed across the flocculator body and then are sequentially connected in series, so that the assembly and the installation are very complicated, and the construction efficiency is low.
