Abstract


The objective of this work was to introduce an advanced wastewater treatment technology; co-polymerized polyvinyl difluoride (PES)-polyethylene glycol (PVP) membrane system for anaerobically-pretreated palm oil mill effluent (POME) treatment. The co-polymerized hollow fibre membranes were fabricated using a wet spinning technique and then used to remediate POME as the feedstock. The physicochemical properties of the POME were analyzed before and after treatment with the hollow fibre. The analyzed parameters included chemical oxygen demand (COD), colour, total suspended solids (TSS), turbidity (TDS), and total nitrogen (TN). A preliminary test was carried out using distilled water before continuing with POME as a feed solution. The average permeate flux obtained by the PES-PVP membrane was 70 L/m2.hr with a slight flux decline that is probably due to the attachment of foulants compounds on the membrane surface and pores. The synthesized modified membrane reduced the COD, colour, TSS, TDS and TN by 92.1, 86, 97.89, 99.98 and 80.26 %, respectively. In conclusion, it can be said that the modified PES-PVP membrane demonstrated excellent performance in treating the POME to produce a permeate with better qualities.
