“…Recently, Usher et al (17) and deKretser et al (18) have proposed a stepped pressure filtration strategy for rapid measurements of the dewatering parameters, which should be highly convenient for model-based design and scale up studies. This quick and absolute method is ordinarily feasible only in an offsite laboratory environment.…”

“…For the operation of a GBT, the operator requires a knowledge of the relationship between the rate of slurry application, initial slurry concentration, and the belt speed to achieve a consistent product quality and throughput. This model, although not complete, provides the foundations for the establishment of such relationships, based on slurry properties which can be determined in the laboratory (DeKretser, 2001).…”

The modeling of gravity driven batch filtration is dicussed in which the Keywords: Gravity filtration, belt thickeners, belt filters, drying beds, flocculated suspension ObjectiveThe objective of modeling filtration under declining pressure is to establish the relationship between the rate of filtrate flow, the slurry physical properties and the design parameters of the device. This knowledge can be used to improve the design of sludge "drying" beds and more, particularly, gravity belt thickeners.

“…Below a particular solids fraction (the suspension gel point, denoted φ g ) the compressive yield stress is identically zero (Landman and White, 1994): the suspension has not yet formed a network and cannot bear weight. For φ > φ g , the compressive yield stress is non-zero, and experimental techniques are available for measuring it for any given suspension (Green et al, 1996(Green et al, , 1998de Kretser et al, 2001;Usher et al, 2001). …”

When the initial feed solids fraction is sufficiently large and/or the initial suspension is sufficiently tall, the densification process has little effect on the solids fraction observed at the bottom of the settler.
