     Abstract Ammonia treatment in a tilapia pond is considered of great significance, for cleaning and changing water in the pond can cost substantially while ammonia has a high toxicity to aquatic animals. In the experiment of the treatment of tilapia wastewater, a 10 L column reactor and a 10 L baffle reactor were employed. Two biofilter materials included bioball and fiberglass while two types of wastewater were synthetic wastewater and authentic wastewater. From experimenting on synthetic wastewater, it was found that on the same surface area of biofilter media, the baffle reactor could treat ammonia most effectively, yet the water was not reusable for tilapia culture. Therefore, the experiment was further conducted to enhance efficiency in the wastewater treatment for aquaculture. In the same-volume reactors, the surface area of fiberglass could be increased owing to fiberglass having higher void percentage. In contrast, the surface area could not be increased in the case of bioball because of their rigid shape and lower void percentage. Thus fiberglass was used instead in the experiment to enhance the efficiency in wastewater treatment. It was discovered that the biofilter system with the fiberglass used as the biofilter media on the 2.4 m2 could remove the ammonia in the wastewater, specifically decreasing it to 0.2 mg/L, which contributed to the reuse of water for a closed recirculation tilapia culture system.
