The TSS concentration with Nano-sized particle in mine drainage is caused by clay minerals which are dominated by montmorillonite type. Therefore, a vast chemical agent is usually used to treat TSS concentrations of liquid waste less than 300 mg/L based on government regulation. However, in this case, the chemical flocculant triggers the onset of secondary pollutant because of carcinogenic and non-biodegradable conditions. This study aims to observe specific fungi, Marasmius sp, as bio-flocculant for the treatment of mine drainage with extra high TSS. The fungi can produce a biodegradable polymer that precipitate the montmorillonite with two-mode action, namely bio-flocculant polymerization and mycelial trapping. A role model was performed in a laboratory-scale less than 1 L in several graduated/measuring cylinders under 22-30 °C. The results of clarity and flocculation rate tests indicated that the minerals in the mine drainage samples from PT.BC mining excavation area, had been precipitated rapidly. The clarity test by using spectrophotometer indicated that eighty six percent (86%) clarity value averagely in one-hour treatment, while the TSS concentration amount decreased down to 110.1 mg/L from original measured at 11,000 mg/L based on the flocculation rate test.[/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]Bio-flocculant,Concentration,Mine drainage,Total suspended solid[/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 would like to thank the PT.BC for the mining water sample and the Research Institution and Community Services (LPPM) of Bandung Institute of Technology for the P3MI research publication funding.[/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/10.1063/5.0007421[/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]
