The filter medium resistance was calculated for three 2 types of filters with varying pore size before and after regeneration. The first data points of each run (i.e. t=0s) were used in calculating the filter medium resistance as the Rc (i.e. cake resistance) term can be neglected since the filter cake, presumably had yet to form. Table 1 below provides a summary of all the filter medium resistances obtained for each run completed. Filter resistances here are given in the form of Rfη, thus in units of mPa*s*m-1, since the viscosity of the solution was not measured. This is an accepted practice as can be seen in Ullmann’s Encyclopedia (Alt, Ripperger, & Gosele, 2011). The regenerated filters are denoted by a (R) after the filter letter.
