| dc.description | The effluents from the food industries have high contents of oils and fat, so it is necessary to treat these effluents in order to comply with the National Standards. The effluents in this scope were characterized by high amounts of oils and fat (10447,80 mg / l), BOD5 (1600 mg / l), COD (28900 mg / l), turbidity (1091,5) and pH (8,7). The objective of this thesis is to optimize the wastewater treatment of the DANEC company. Through the implementation of a primary treatment. Two primary treatments were executed: dissolved air flotation and electroflotation at 5, 15 and 30 minutes, respectively, with an adjusted pH of 5 and the use of the electrolytic medium with H2SO4. Subsequently, the coagulation-flocculation technology was applied, using 40 ml of 0,075 percent aluminum polychloride and 23 ml of the 0,1 percent anionic polyelectrolyte adjuvant. The experimental designs that were used, allowed us to conclude that the best treatment was the dissolved air flotation method with a residence time of 5 minutes, due to the turbidity removal of 99,5 percent; COD of 99,5 percent and composition of oils and fat of 99,8 percent, reaching values of 5,2 NTU, 39,6 mg/l, 95,3 mg/l and 14 mg/l, respectively. This treatment complies with the maximum permissible limits of the Regulatory Legal Framework of the Ministerial Agreement. | en |
