This paper presents experiments showing the existence of a critical filtered volume (CFV) when operating colloid dead-end filtration. The CFV is here defined as the filtered volume below which there is no irreversible (with respect to a break in the filtration) fouling on the membrane surface: it has thus the same meaning as cross-flow critical flux but applied to a dead-end process. The existence of the CFV is demonstrated when filtering stable latex or clay suspensions in constant-flux filtration experiments with alternating rinses: in contradiction to the current view, an irreversible deposit is not formed as soon as dead-end filtration begins. This critical filtered volume is shown to be dependent on the suspension stability and to be fully linked to the permeate flux: for permeate fluxes of 80 and 110 l h −1 m −2 the CFV is, respectively, 82 and 65 l m −2 for latex particles. Analyses of results are made by depicting the transition between concentration polarisation and deposit formation considering a critical osmotic pressure, which appears to be a characteristic of the fouling potential of a suspension. The results are discussed in the light of how this concept could lead to an interesting way to control and develop a strategy to operate filtration in dead-end mode.

“…membrane modules) thereby increasing both the plant footprint and capital cost. The benefits of longer filtration cycles and less chemical cleaning may not justify the additional expense in a purely economic sense but may become viable if environmental sustainability is an important consideration [11]. Membrane materials will have a significant effect on the fouling capacity for any particular compound as well as the reversibility.…”

“…Integration of MF into a membrane bioreactor typically involves membrane filtration of high solid content feed, which has advantages (low excess sludge) and disadvantages (membrane fouling). An alternative approach is to use MF after settling the biomass so that relatively low solids content feed goes to the membrane (Parameshwaran et al 2001).…”
