Coagulation process, which is the combination of agglomeration and flocculation, is mainly used to remove colloids.

Coagulation process, which is the combination of agglomeration and flocculation, is mainly used to remove colloids. A: 正确 B: 错误

The efficiency of coagulation process is not good during the condition of low temperature, because ( ) A: coagulants will not hydrolyze completely B: the hydration of colloidal particles is enhanced, which hinders the coagulation process C: the viscosity of water is high, so the Brownian motion is weak, making it difficult for colloids to aggregate D: The rate of coagulants hydration is too high
