An almost identical procedure was followed for this experiment as in the experiment performed on April 23rdExperiment 7. A lime slurry of 100 grams of lime plus 1 liter of tap water was prepared for each apparatus, as well as a lime slurry of 124.5 grams of lime prepared in 1 liter of tap water and then diluted further with 14 additional liters of water for the stock concentration. The difference between the two experiments is in the use of the blender to prepare the slurries.
For the 100 grams of lime that were to be fed into the vertical column, the blender was used for 5 minutes on "liquefy". Unfortunately, at the end of the 5-minute period for the second 100 gram slurry, the blender overheated and became inoperable. Therefore, the mixer had to be used to blend the remaining lime slurry needed for the stock concentration. It is suspected that the mixer does not provide the same particle uniformity that the blender does.
