The present investigation was carried out with the purpose of evaluating the reduction of pollutants in the effluents tested from the fish canning industry using air nanobubbles. The study was carried out on a laboratory scale using air nanobubble generator equipment. The results were reduced by 89.5% of total suspended solids (from 6180 mg/L to 645 mg/L), 76.5% of BOD5 (from 7350 mgO2/L to 1730 mgO2/L), 73.6% of COD (from 10356 mgO2/L to 2735 mgO2/L) and 79.4% of oils and fats (from 96.3 mg/L to 33.2 mg/L). It was concluded that the treatment using air nanobubbles can significantly reduce the concentration of the pollutants present in the effluents of the fish canning industry.
