“…A study on cold sterilization of beer showed that precipitation of large particles, chemical interaction between solutes and membrane, absorption of small particles or solutes by inside wall ca. 254.9-500 µm long by 64 µm wide (cercariae) (Braun et al, 2018) or 70-175 µm long by 40-70 µm wide (egg) (Jing et al, 2018) of membrane pores, etc. may be associated with the mechanism of membrane fouling which may cause the following consquences: complete pore blocking, partial pore blocking, cake formation and internal pore blocking (Esmaeili et al, 2015).…”
