A) B) 1732 To discriminate the fouling mechanisms, the flux decline behaviour during rough beer microfiltration can be examined by estimating the time course of the overall resistance (RT) to filtrate flow as follows: vP T J η TMP R = (3) where ηP is the permeate viscosity, and TMP the transmembrana pressure difference. The quasi steady-state flux (Jv,ss) was reached after about 1 h, independently of the turbidity (H) of rough beer.	cache/cet-6683.pdf	txt/cet-6683.txt
