E. Hence, A-7 and A-8 leads to: (A-9)

. Eq, A-9 has to be integrated from the feed to the retentate concentration and from 1 to VRR

. Eq, A-11 can be rewritten to get Eq. A-12

E. Actually, A-2 (solute mass balance) is modified using an average value of the permeate concentration (calculated by Eq. A-5) because of our assumption of cross-plug flow, p.15

A. Eq, A-4 becomes A-16: (A-16

. Eq, A-18 can be rearranged to give the abatement (Eq. A-19). (A-19
