        The present study has measured the velocity distribution in a three-dimensional shape model of the rectangular settling tank using PIV system. The experiment system consists of hi-speed camera, laser and host computer. Reynolds number based on the guide wall height(H=25mm) has been applied during the whole experiments. The results showed that recirculation flow in settling tank exists and a internal flow weakly influenced by Reynolds number at Re=5×103 greater.

        In the present paper, batch and semi-continuous settling characteristics of a binary calcium carbonatewater system were investigated. Using experimental data of batch settling characteristics, a graphical analysis for a semi-continuous thickening column was developed and compared with experimental results on the basis of Kynch theory, only where the feed velocity line was within the limits of Kynch theorem Ⅲ. The analysis showed good agreement with experiments. Quite erroneous results, however, was observed for the analysis of a sludge region on the underloaded operation, which was considered due to the deviation from the limits of theory.
