Avaliação de parâmetros eletroquímicos para dois sistemas de escoamento, tortuoso e linear, em um reator eletrodialítico.

Abstract

The present work has as objective to study the performance of a prototype of an electrodialysis reactor for the purpose of desalination of sodium chloride solutions via electrodialysis. O reactor has been studied for two types of flow systems: tortuous and linear. The main parameters investigated for both systems were as follows: effect of electric potential as a function of power flow, current density, ohmic resistance, current efficiency, potability time and energy consumption. It has been observed that energy consumption decreases as the feed flow increases. While the time when the saline remains under continuous circulation during the process until it reached a concentration in the potability range, it varied decreasing for the tortuous outflow system and increasing for the linear flow system as a function of feed flow.
