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
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
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。 ( )
- What isthe essential characteristic of colloid? A: Tyndall effect B: Brownian motion C: Colloidal particles size ranges from1nmto 100nm D: colloidal particles charged
- The performance of coagulation process will be better when low-turbidity water is treated. A: 正确 B: 错误
- If △H value of a reaction is positive, the conditions that must be a spontaneous process is(). A: △S value is positive and high temperature B: △S value is positive and low temperature C: △S value is negative and high temperature D: △S value of is negative and low temperature
