Question

In sedimentation, l – clear liquid zone, t- thick suspension zone, s- solid zone. With concentration of solids as the y-axis and the time as the x-axis, which curve does the following represent?

(a) l-t interface

(b) t-s interface

(c) t zone

(d) none of the mentioned

I have been asked this question in quiz.

This interesting question is from Unit Operations topic in section Sedimentation and Centrifuge, Mixing, Size Reduction and Separation and Material Handling and Transportation of Food Engineering

Answer 1

The correct choice is (b) t-s interface

The best explanation: The above curve shows the t-s interface. The concentration of solids increases and then becomes constant.
