PROCESSO DE ELETROCOAGULAÇÃO-FLOTAÇÃO: INVESTIGAÇÃO DOS PARÂMETROS OPERACIONAIS PARA O TRATAMENTO DE ÁGUAS RESIDUAIS DA INDÚSTRIA DE PESCADOS

The objective of this study was the utilization of an electrocoagulation-flotation process to evaluate the treatment of a real wastewater from fish industries (Brazil - SC). This type of effluent is usually treated by conventional processes, which are often not sufficient to meet the desired final quality of legal environmental requirements. The effect of current density, pH and treatment time was evaluated. The best experimental conditions for the process were current of 5 A, potential of 15 V and distance between electrodes equal to 10 mm. Under these conditions, the removal of the contamina...
