Fouling Characteristics

Fouling characteristics of crossflow flat-sheet membranes for two Nanofiltration (NF), one Ultrafiltration (UF), and one Microfiltration (MF) membranes were analyzed using 12.5 parts per million (mg/L) FeCl3 solution and 350 mg/L copper nanofluid. FeCl3 solution represents dissolved contaminant whereas copper nanofluid simulates particulate contaminant. The spatial and temporal fouling evolutions were captured using digital photography and analyzed using ImageJ software. FeCl3 fouling studies for one NF membrane showed uniform fouling whereas for the other NF membrane, isolated fouling was apparent and the fouling initiated at the outlet then gradually extended towards the inlet. Copper nanoparticle fouling studies analyzed through gravimetric and image processing revealed spatial and temporal fouling developments. Both non-equilibrium and equilibrium fouling stages/regions were evaluated through fouling density analysis.

Fouling Characteristics

In this study, the variation of Zeta potentials and distribution of molecular weight in Extracellular Polymeric Substances (EPS) and soluble microbial products (SMP) were investigated. It is indicated that the salinity is effect on Zeta potentials significantly. When the salinity increased from 0 g/L to 35 g/L, the Zeta potentials decreased gradually. The average molecular weight is mainly over 30 KDa in EPS and SMP at 0 g/L salinity, and is mainly below 10 KDa at 10 g/L and 35 g/L salinity. This result is evident that the variation of molecular weight is contributed to high salinity.
