Research advances and challenges in one-dimensional modeling of secondary settling Tanks - A critical review
2014, Water ResearchCitation Excerpt :The colloidal solids within the well-flocculated suspension, however, only constitute a relatively small fraction of the total weight, hence their contributed osmotic press could be indeed insufficient to retard the settling behavior (Fitch, 1993). Dynamic compression force is characterized as the force that causes the particle deceleration as it approaches the discontinuity or settles within a region having a concentration gradient, such as the transient zone (Dixon, 1977a, b, 1978; 1981). It originates from the excess local pressure required to squeeze fluid out interstitial floc areas to make them more concentrated (Fitch, 1993).
