Modeling of the Capillary Suction Time of Kaolin Slurries Using Chemometrics.

Sharma-SK; Stanley-DA
Ch in Adv in Filt & Sep Tech Sep; 5::319-26
For this investigation, eight different concentrations of kaolin slurry were evaluated. Factor analysis of the data showed that there were two physically significant factors affecting the experiment. The first factor was applicable to the data below X = 3 cm and had an exponential characteristic, while the second factor applied to the data between X = 3 to 6 cm. The data between 3 and 6 cm were reproduced adequately by tiller's equation. A regression equation was used to predict the data between 0 and 3 cm. The combination of both equations reproduced the results to within +/-4 pct. It was found that the average specific resistance is inversely proportional to the clay slurry concentration and that as the concentration increases, the average resistance decreases. Finally, this investigation showed that factor analysis was successful in finding significant factors that had physico-chemical meaning; therefore, it could be applied to future dewatering studies.
