Catfish farming is an important livelihood source in the Philippines; however, due to improper management of wastewater from concrete ponds, very high- water consumption, increased labor, and environmental pollution results. The wastewater from catfish ponds contains high organic matter, ammonia, and suspended solids, all harmful to fish health and the ecosystem if released untreated. Therefore, the study focused on the design and development of a filtration system for catfish wastewater for small- and medium-scale aquaculture purposes. The developed system integrates sequential treatment process, coagulation, flocculation, sedimentation, and a biofilter, using cost effective and locally available resources. Moringa oleifera was utilized and impurities, while sand, gravel and charcoal were employed as biofilter to further purify the wastewater. Submersible and centrifugal pump were used to ensure controlled water flow and effective treatment at each Performance testing is conducted to evaluate the filtration system efficiency based on the water parameter such as pH level, ammonia concentration and total dissolved solid (TDS). The test result showed a significant reduction in TDS, ammonia level, while the pH still maintains the value within acceptable ranges for the farm. The treated water was suitable non potable apply such as cleaning livestock area and watering. The developed system filtration demonstrates a sustainable, practical, and low cos solution for improving wastewater management in catfish farming.
