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

D: The rate of coagulants hydration is too high
举一反三
- The performance of coagulation process will be better when low-turbidity water is treated.
- G value and GT value are employed to design coagulation tanks， because they can describe the coagulation process comprehensively。 （ ）
