COAGULANT EVALUATION SODIUM ALUMINATE ALKALIZED AT MATERIAL REMOVAL ORGANICS FROM INDUSTRIAL EFFLUENT FROM THE DAIRY INDUSTRY

Objective: The food production area is one of the most consume water and produce effluents liquids per unit of production. In the dairy sector, one of the main branches, there are one production significant amount of effluent liquids with a high matter load organic. You waste generated by this industry they are characterized by the great presence of matter organic, which makes essential to use an Effluent Treatment Station (ETE) for treatment of these effluents before disposal in bodies of water. Theoretical Framework: So, this works he had as goal propose the implementation of a decantation system primary at the ETE of a dairy industry, aiming improve the efficiency of the treatment system. Method: An approach adopted involved the execution of the jug test using 2,000 mL containers, with the aim of evaluating the pollutant removal capacity. The process included adjusting the pH to 8.5, through the incorporation of Sodium Aluminate Alkalized and the application of different dosages of coagulant - 0.4 ml, 0.6 ml and 0.8 ml of PAC - and flocculant - 6 ml, 8 ml and 10 ml. Resultados e Discussão: You results obtained indicated that the Sodium Aluminate Alkalized demonstrated efficiency to the collaborate at separation between the components solids and liquids of the liquid to be treated in the phases subsequent ones. That contributed to adapting the effluent to the requirements settled down by standards environmental in force, facilitating your destination to the receiving body in a way more effective.
