| dc.description.abstract | Water quality is a critical factor in fish production. Biofilters are used to improve water quality. Peanut is one of the major field legumes grown by the farmers in the Philippines. Peanut generates an agricultural waste (shell). Peanut shell is very woody, converting it into activated carbon will maximize its adsorptive properties. The study was carried out to develop a biofilter system using peanut shell activated carbon as filtering media for aquaculture. The filtration system was designed using peanut shell activated carbon and sand as filter medium and local available materials. The biofilter system was fabricated according to the proposed design using PVC pipes. The peanut shell activated carbon as filter medium were evaluated using multi parameter tester. Water quality parameters such as temperature, dissolved oxygen, pH level, and ammonia concentration were gathered for the analysis of the study. The filtration system was composed of three different treatments, peanut shell activated carbon with 2 mm, 4 mm, and 6mm size. The data were laid out in Completely Randomized Design (CRD) with three replications. Results showed the fabricated biofilter system using peanut shell activated carbon can decrease the water temperature to 28.03 °C, pH level to 8.29, and ammonia concentration to 0.19 mg/L and increase the dissolved oxygen to 4.47 ppm which is favorable for fish production. Evaluation of the filtering capacity resulted to the lowest filtering capacity of 0.26 L/min for 2 mm size of peanut shell activated carbon. Small size gives slow filtration capacity and slow filtration capacity gives better qualities for treated water. | |
