The efforts to improve the stability of membrane filtration in applications for wastewater treatment or the purification of drinking water still dominate the research in the field of membrane technology. Various factors that cause membrane fouling have been explored to find the solution for improving the stability of the filtration and prolong membrane lifetime. The present work explains the filtration performance of a hollow fiber membrane that is fabricated from polyethersulfone-2-(methacryloyloxy) ethyl phosphorylchloline while using a sodium alginate (SA) feed solution. The filtration process is designed in a pressure driven cross-flow module using a single piece hollow fiber membrane in a flow of outside-inside We investigate the effect of Ca and Mg ions in SA solution on the relative permeability, membrane resistance, cake resistance, and cake formation on the membrane surface. Furthermore, the performance of membrane filtration is predicted while using mathematical models that were developed based on Darcy’s law. Results show that the presence of Ca ions in SA solution has the most prominent effect on the formation of a cake layer. The formed cake layer has a significant effect in lowering relative permeability. The developed models have a good fit with the experimental data for pure water filtration with R2 values between 0.9200 and 0.9999. When treating SA solutions, the developed models fit well with experimental with the best model (Model I) shows R2 of 0.9998, 0.9999, and 0.9994 for SA, SA + Ca, and SA + Mg feeds, respectively.

“…In particular, organic fouling is often mitigated through a variety of pretreatment processes. As a result, extensive research on pretreatment processes such as coagulation (Kimura et al 2014), biofiltration (Netcher & Duranceau 2016), and preoxidation with ozone (Van Geluwe et al 2011) continue to be of vital importance.…”

The effect of integrating ozone ahead of coagulation, flocculation, and sedimentation (CFS) as pretreatment to ultrafiltration (UF) membranes was investigated at the bench scale for treatment of a surface water containing organic foulants. Ozone was applied before a CFS–UF process and compared with a CFS–UF condition without ozone as the control. While CFS alone reduced turbidity by 27%, CFS increased turbidity by 61% while applying ozone. When integrated with CFS and UF, however, ozone reduced filtrate true color by 40%, ultraviolet absorbance (UVA) at 254 nm by 10%, and specific UVA by 30%, relative to the control, indicating that while ozone had impaired turbidity removal during CFS pretreatment, it had improved removal of aromatic‐rich organics. Fluorescent excitation–emission matrixes confirmed that humic acid‐like and fulvic acid‐like substances known to cause irreversible fouling were retained on the control membrane but were absent on the membrane when ozone was integrated with CFS pretreatment.
