Abstract

Removal of manganese in contaminated groundwater using filtration is one of the most treatment systems.
The objective of this research was to study the efficiency of fixed-bed adsorption column using eucalyptus biochar and potassium permanganate-modified eucalyptus biochar as filter media to remove manganese from groundwater. The initial manganese concentration of 0.723 +- 0.002 mg/L was continuously fed to the top of column at a flow rate of 5 L/d. Water samples were collected periodically within 24 hours. Thomas and Yoon-Nelson models were used to describe the adsorption performance. Results showed that adsorption capacity of eucalyptus biochar was 1.812 mg/g higher than that of modified eucalyptus biochar (0.769 mg/g) as it has higher iodine number. The adsorption times at 50% breakthrough of eucalyptus biochar and modified eucalyptus biochar were 1,020 minutes and 240 minutes, respectively, which were consistent with the Yoon-Nelson model. Use of EB and MEB as local filter media can reduce the cost of improving community water quality.
