    In thickening applications, the hydraulic flow rate, for the sizing, constitutes a limiting factor. Therefore, sludge must be extracted from the clarifier's recycling pit in order to obtain concentrations of at least 7 8 g suspended solids 183; L 1 at the machine's inlet.

    They also found that consideration of diffusion factors alone failed to predict the perception of several taste compounds in thickened solution, in which cases they assumed mass transfer to be non rate limiting. However, there was no clear rationale behind which compounds/tastes could be modelled in this fashion and which could not.
