Abstract

Global population growth and resource limitations have increased the urgency for sustainable food production systems. Aquaponics combines aquaculture and hydroponics, offering 90 percent water savings compared to conventional methods. System effectiveness depends on water quality management, particularly ammonia regulation. Ammonia concentrations exceeding 0.05 mg per L cause physiological stress in aquatic organisms and disrupt nitrification processes. This research develops a smart integrated monitoring system with electrocoagulation technology for ammonia reduction in household aquaponic systems. The system uses stainless steel 316L electrodes at 12 to 24V DC with 2 to 3 cm electrode spacing. Ammonia reduction occurs through electrochemical oxidation, in-situ coagulant formation, and adsorption. The prototype measures 200 cm by 100 cm by 100 cm with five compartments: pre filtration, electrocoagulation, ozonation, sensor, and post filtration. Methodology includes system development, parameter optimization with 15 to 60 minute retention time and 10 to 30 mA per cm2 current density, ammonia elimination efficiency evaluation, and organism growth analysis. Experimental design employs factorial design with 3 replications and ANOVA analysis. The novelty lies in integrating electrocoagulation, ozonation, and smart monitoring for household aquaponic applications.
