In spite of it is a dangerous substance already defined as carcinogenic, formaldehyde even widely used in industry and in the academic environment, in Brazil, it still does not present a regulation that delimits what can be considered a safe disposal. Based on the literature, it was defined that 1.61 mg L-1 of formaldehyde represents a safe concentration to be lead to sewage. The proposal of this study is to establish a complete oxidation model of this residue, followed by its simulation using different types of reactor models. The entire process was structured to satisfy the demands from the human and animal anatomy laboratories, both present at Federal University of Jequitinhonha and Mucuri Valleys, in the city of Diamantina, MG. The corpses and carcass washing process implanted provides the effluent which will be treated. The reaction model has three stages, the first follows zero-order kinetics and the other two follow a pseudo-first order kinetic, their specific reaction rates were 0.0457 mol L-1 min-1, 0.0702 min-1 and 0.0144 min-1, respectively. A 150 L BSTR presented satisfactory operation, with a batch time of 7 minutes to achieve a safe disposal. Further tests with the real effluent ought to be implemented in order to compare with the results from the synthetic effluent.Downloads
