Abstract

Removal of particulate matter from OMWW using cartridge filtration seems to be more reasonable compared to sedimentation and sand filtration, because the bulky structure and flotation of the settled sludge makes the sedimentation process inefficient. Sand filtration is not a feasible solid separation process for OMWW due to rapid clogging and enormous sludge volume coming from backwashing. In this study, cartridge filter filtration of OMWW using 20 gm and 5 gm cartridge filters after acid cracking was applied as pretreatment step. A Box-Wilson statistical experiment design method was used to investigate the effects of operating parameters such as pH of OMWW and filtration time on TOC and TS removal efficiencies. Both cartridge pore sizes gave satisfactory results. Low pH value and long filtration time improves the removal efficiencies of TOC and TS.
