dc.description.abstractThe disposal of pig manure and the odor associated with their storage facilities are two of the main problems connected to the increasing swine production in terms of surface water, groundwater, and air quality. Converting swine manure into biochar can help mitigate its negative environment effects while also generating sustainable energy and value added biochar. This study aims to evaluate swine manure as a precursor for producing activated carbon. Also, this is to assess the potential of the product activated carbon in adsorbing various contaminants such as biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia, phosphate and total coliform present in piggery wastewater. Swine manure was carbonized through an improvised kiln and activated using calcium chloride (CaCl2). The activated carbon was charactyerized by its physical properties such as percent ash, percent moisture, and bulk density. Scanning Electron Microscopy (SEM) was used to analyze and compare the pore structure of the activated and carbonized swine manure. The study used different amounts of filter media. Treatment 1 with 4-inch AC thickness, Treatment 2 with 6-inch AC thickness and Treatment 3 with 8-inch AC thickness. For the characterization of activated carbon, the ash content of swine manure activated carbon was 18.87%, the moisture content was 9.58%, and the bulk density was 0.26 g/mL, which were within the range of acceptable levels. The operating time for Treatment 1 was 0.45 hr, Treatment 2 was 1.18 hr, and Treatment 3 was 1.40 hr. Their filtering capacities were 2.24, 0.86 and 0.72 liters per hour, respectively. The results showed that among the three treatments, the 8-inch AC thickness (T3) proved to be the most effective in adsorbing BOD (63.76%), TSS (89.94%), ammonia (97.74%), phosphate (89.97%), and total coliform (63.76%). Statistical analysis showed that there are significant differences among the treatments.
