A Study on Experimental Analysis of Semi-Continuous Settling Tank using Characteristics of Solid Sedimentation in the Binary $CaCO_3$-Water Slurry

탄산칼슘-물 이성분계 슬러리의 침강 특성을 이용한 반연속식 침전탑의 실험적 해석에 관한 연구

In the present paper, batch and semi-continuous settling characteristics of a binary calcium carbonate-water 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.
