Abstract

Nutrient removal in wastewater before disposal into water bodies. One of the common adsorption materials is biochar, which can be made from coconut shells. Coconut shells also grow in the highlands, which are also utilized as agricultural areas. This study was performed to test the ability of biochar to remove ammonium, nitrate, and phosphate in a batch adsorption experiment. The results show a maximum ammonium, nitrate, and phosphate adsorption capacity using highland coconut shell biochar of 5.45, 4.85 and 6.57 mg/g, respectively. The best-fit isotherm that describes the ammonium, nitrate and phosphate adsorption process is the Langmuir isotherm. The best-fit adsorption kinetics are Pseudo 1st order. The results of this study indicate the potential of coconut shells from the highlands to remove nutrients from wastewater.
