Antifouling polysulfone membranes blended with green SiO2 from rice husk ash (RHA) for humic acid separation

This study investigated the effects of silica prepared from rice husk (RHA) as an antifouling additive in the polysulfone (PSf) membrane. The ultrafiltration mixed matrix PSf/rice husk silica (RHS) flat-sheet membrane was prepared via phase inversion technique at different percentages of silica conc...
