Among the various methods for recovering lignin from black liquor, membrane separation has gained prominence in paper industry due to its advantages of uniform molecular weight distribution, high recovery rates, and absence secondary pollution. However, over time, particles tend deposit form a cake layer on surface, leading fouling decline filtration flux. To address this issue, study investigates construction ceramic membranes with radial rib patterns, examines effects different trans-membrane pressure differences patterns surface shear force particle deposition. The research findings indicate that at difference 0.5 bar blade rotation speed 1000 r/min, experiences highest force. Compared those without can more effectively delay deposition particles. Furthermore, it was observed combining coarse fine exhibit pronounced increase
