Silica synthesized using the sol-gel method resulted in particles range 189–227 nm in size. Characterization with FTIR further confirms the silica cluster produced from the synthesis. The membrane was successfully made in the form of flexible paper sheets in three compositions: T1 (BNC 60%, microcellulose 20%, and silica 20%), T2 (BNC 50%, micro cellulose 20%, and silica 30%), and T3 (BNC 40%, microcellulose 20%, and silica 40%). The SEM characterization shows the constituent elements, BNC, microcellulose, and silica, were evenly spread on the resulting flexible membrane sheet and shows matrix of BNC and micro cellulose while the space between them are filled in by silica particles. EDS characterization are carried out to observe morphology and dominant element on the membrane. Performance test of the membrane was done at pressure 4 bar. The T3 membrane had the largest maximum flux value of 4.412 × 103 l m-2 h. The T2 membrane had the highest salt rejection value of 4.89% in the first minute, but the value was lower than T1 at the end of five minutes. The salt flux and rejection values of the entire membrane tend to decrease with time due to clogging on the membrane surface.[/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]Banana peel wastes,Constituent elements,Flat sheet membranes,Flexible membranes,Membrane surface,Performance tests,Research reports,Silica particles[/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]Bacterial nanocellulose (BNC),Banana peel waste,Silica,Water filter 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][/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/10.1088/2053-1591/abba3f[/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]
