The permeate flux, J, steeply decreased at the
very beginning of these experiments, e.g. the
permeate flux at 3 bar and 4 m/s after 1 min of
operation was 3 1% of the corresponding pure
water permeation flux.
J increased for increasing operating pressures
and crossflow velocities, reaching a threshold
at 4 bar for the lowest velocity (2 m/s).
The rejections with respect to the proteins, oil
and grease, VS, and TS ranged 63-66%, 64-
69%, 55-64%, 1 S-22%, respectively.
The variation of the rejections with regard to
the crossflow velocity and the operating pressure
were not significant, thus apparently the
rejections were constant irrespective to the
operating conditions.
