Aquaculture wastewater often contains high levels of nitrates and phosphates, posing environmental risks. Electrocoagulation—which uses iron, aluminum, and stainless-steel electrodes at currents of 1, 2, and 3 Amperes—offers a possible solution by efficiently lowering these pollutants. During a 30-min treatment at room temperature, important variables like the electrode type, the concentration of pollutants, and the energy used were carefully evaluated. Iron electrodes operating at 3 Amperes were the most effective, which reduced nitrates by 36.23% and phosphates by 93.84%. The electrodes used 9.69% of its mass and 10.50 kWh/m3 of power. The pseudo second-order kinetic model best described the removal efficiency of both nitrates and phosphates, which suggested a concentration-dependent process. All things considered, electrocoagulation showed a great deal of promise as an affordable method of pollutant removal, improving aquaculture environmental management practices.
