Question

Which of the following describe the process of coagulation?

a
It is a process by which a liquid is converted into a solid or semisolid mass.
b
It is a process that creates disinfection by-products.
c
It is a process by which a liquid mixture is separated into its individual components.
d
It is a process where the combined rapid mix-slow mix process with the use of a chemical that in combination of the the mixing process create floc.

Answer 1

Answer: D. It is a process where the combined rapid mix-slow mix process with the use of a chemical that in combination of the mixing process creates floc.

Step-by-step explanation:

Coagulation is a process used in water treatment to remove suspended particles from water. It involves the use of chemicals (typically aluminum sulfate or ferric chloride) that are added to the water to destabilize the suspended particles and create larger, heavier particles called floc. The floc can then be removed from the water by sedimentation or filtration. The process typically involves a rapid mix phase, followed by a slow mix phase, where the chemical is added and the floc is formed.
