This paper deals with an examination on a technique for evaluating solid/liquid separation effectiveness in sludge without chemical conditioning for a vacuum filter as viewed from both quantity and quality of the separated liquid. It uses a statistical model based on the analysis of the separation curve (i.e., the speed of separation) through a multivariate analysis of variance. Among the three separation factors, suction force is recognized as the main effect. Also, quality of the separated liquid resulting from the filter experiment was examined. Moreover, the analysis was extended to the quality of the separated liquid as related to the speed of separation.
