As the highest permeation flux during the
previous set of experiments, 32.0 l/(h*m2), was
obtained at 4 bar and 4 m/s, the subsequent concentration
experiment was carried out at these
operating conditions. The data relative to the
permeation flux and proteins rejection during the
concentration experiment of the microfiltrated
fish meal effluent by NF, as a function of the
volume reduction factor, VW, are shown in Fig. 2.
The conclusions to be drawn are the following:
