Explanation

It is also called coagulant. It refers to the substance used to condense solutes, colloids or suspended solids in aqueous solution into flocs and precipitation. In industrial water treatment, water treatment agent in the process of coagulation and sedimentation is collectively referred to as coagulant. Gellants are divided into two categories: inorganic and organic. The gelation mechanism is complex, and the basic principle is to increase the diameter of suspended ions in water and accelerate their settling speed. The specific gelation effect is achieved through two factors: physical and chemical effects. Chemical factors neutralize the charge of particles, reduce their potential, make them unstable particles, and then aggregate and settle. These types of gelling agents are mostly low molecular inorganic salts. The physical factor is that the gelling agent changes small particle aggregates into flocs through crosslinking and adsorption, and most of these gelling agents are macromolecule substances.
