ZnO and eugenol were used as additives and introduced into the membrane matrix via the additive blending method. The additives could improve the performance of the PSF membrane due to their hydrophilic nature. The water contact angle (WCA) of the PSF membrane decreased from 67.7° ± 1.2° to 52.8° ± 0.8° when the additive loading was increased from 0 to 5%-wt. The PSF membrane with 5%-wt ZnO and 5%-wt eugenol had pure water permeability and humic substance rejection of 83.8 ± 3.7 L mr2 h~1 bar1 and 95.6%, respectively. In addition, the additives were able to improve antifouling properties, e.g. a recovery ratio (FRR) of 85.4% and relative flux reduction ratio (RFR) of 30.2%. In the antibacterial assay, the membrane displayed 3 mm and 10 mm inhibition zones against Escherichia coli and peat water microorganisms, respectively, probably due to antibacterial properties of the additives.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antibacterial properties,Antifouling property,Inhibition zones,Phase inversion,Phase inversion techniques,Pure water permeabilities,Ultrafiltration membranes,Water contact angle (WCA)[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Additive,Fouling,Hydrophilicity,Phase inversion,Water treatment[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors gratefully acknowledge the financial support from P3MI (Program Penelitian, Pengabdian kepada Masyarakat dan Inovasi) Institut Teknologi Bandung and KARG (KURITA-AIT research grant).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.2166/ws.2019.103[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
