In this work, composite polypropylene-based membrane (PP) with improved anti-organic fouling is prepared by coating polysulfone (PSf)/PEG400/ZnO layer on PP hollow fiber membrane. Separation properties and organic fouling tendency of the composite membrane are investigated during the peat water filtration. Results show that PSf/PEG400/ZnO layer is successfully deposited on PP membrane evidenced by scanning electron microscopy and fourier-transform infrared spectroscopy analysis. ZnO particles increase membrane hydrophilicity shown by decreasing water contact angle from ∼97.7 to 77.1, which results in higher pure water permeability (from ∼16 to ∼46 L.m−2. h−1. bar−1). Higher hydrophilicity also reduces organic fouling tendency of the membrane during peat water treatment. The flux recovery ratio increases from 63 % to 66 % while relative flux reduction decreases from 53 % to 44 %. The composite PP membrane (M-ZnO-40 %) is able to remove ∼70 % humic substances from peat water. Results of this study show that the addition PSf/PEG400/ZnO layer can effectively improve membrane permeability, selectivity, and anti-organic fouling of PP hollow fiber membrane.[/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][/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,Hydrophilic,Peat water,Polymeric membrane[/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]This research is partially funded by Multidisciplinary Research Program provided by Institut Teknologi Bandung and the Indonesian Ministry of Research, Technology and Higher Education under WCU Program managed by Institut Teknologi Bandung.[/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/10.1016/j.jwpe.2020.101158[/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]
