Treatment of industrial wastewater was evaluated through coagulation-fl oculation using starch of Solanum tuberosum L.‘potato’ as an alternative to the conventional management. Assays were performed in a laboratory scale by performing JarTest with two coagulants: aluminum sulfate and aluminum polychloride, and two fl occulants: anionic polyacrylamideand gelatinized starch, making variations in dose, concentration and speed. To determine the ideal parameters, thefollowing response variables were used: Willcomb index, absorbance, turbidity and chemical oxygen demand. Th e besttreatment was when using aluminum polychloride as coagulant and anionic polyacrylamide as fl occulant, reaching areduction percentage of 83.05% in chemical oxygen demand. Even then, the results suggest that anionic polyacrylamidecan be replaced by starch of S. tuberosum when applying a primary treatment to industrial wastewater from a foodcompany located in the district of Ate in Lima, Peru to meet the admissible values set in the Supreme Decree No.021-009-VIVIENDA, with respect to organic matter present in wasterwater.
