In this study, a zirconium oxide ceramic membrane was employed. Experimental investigations were also conducted to assess the influence of coagulant dose and solution pH on the coagulation perfor-mance. Afterward, for microfiltration (MF) and the hybrid process of bio-coagulation-microfiltra-tion, the effect of transmembrane pressure (TMP) was evaluated. The results indicate that the pH of the solution and the dose of coagulant used have a significant impact on coagulation performance. However, the MF process is primarily influenced by TMP. Furthermore, the pH and operating pres-sure were found to have an important influence on the hybrid process. The experimental results showed that the highest removal efficiency for dye and turbidity removal (96.2% and 98.77%, respec-tively) was obtained by hybrid process at pH 3 and TMP of 1.7 bar. For the same previous condi-tions of pH and TMP, the permeate flux increased and reached the highest values. A comparative study between the experimental results and those obtained by simulation with SuperPro Designer software demonstrated close agreement between the findings.eninfo:eu-repo/semantics/closedAccessDyeBio-coagulantNatural coagulantAcorn leavesCoagulationMembrane filtrationMicrofiltrationHybrid processTurbiditySuperPro DesignerArticle10.5004/dwt.2023.29980311144154Q4WOS:0011185649000212-s2.0-85198577540Q3
