permeation flux, Jcrit, during crossflow microfiltration of bentonite suspensions using a tubular
ceramic membrane module was investigated. The investigation determined the effects of
flocculant concentration on Jcrit at various crossflow velocities. The best filtration performance
(highest Jcrit) was obtained at a flocculant dose of 500 mg kg-1 (mg of flocculant per kg of solids)
and at a crossflow velocity of 1.71 m s-1. Particle size has been used as a parameter to fit the
shear-induced hydrodynamic diffusion model to the experimental filtration data.
