DESCRIPTION
This experiment consisted of measuring the upflow velocity with different flow rates and different quantities of lime, while always maintaining a suspended column of lime. This was an initial experiment and hence most of the quantities were taken through approximation. The details of the exact quantities of lime and flow rates as well as the results obtained can be found in the attached file called "ANC-Initial Experiment using Column".
...
The optimum flow rate which could keep the lime suspended without excessive lime coming out (as observed visually) was found to be about 85ml/min.
The figure above below shows the apparatus used for the first trial, it consists in of a tube glass column connected with a water source regulated by a peristaltic pump. The lime was added manually at from the top.Figure - 1. Apparatus for the first trial
