This work shows results obtained in the electrochemical incineration of a synthetic vinasse with initial chemical oxygen demand (COD) of 75.096 g L(-1) in aqueous media (which resembles vinasse industrial wastewater). Electrolyses in a filter-press-type FM01-LC electrochemical reactor equipped with a three-dimensional (3D) boron doped diamond electrode (BDD) were performed at Reynolds values between 22

Electrodisinfection of wastewater has been investigated extensively in the past, although a consensus over the use of direct current (DC) or alternating current (AC) as the most efficient electricity source has not been reached to date. The research presented herein compares the use of DC and AC in electrodisinfection of municipal wastewater aiming to provide conclusive evidence on the benefits of using one type of current over the other. During the experimental phase, a bench-scale electrodisinfection reactor equipped with iridiu m o xidecoated titanium electrodes was operated continuously, and E.coli inactivation, free and total chlorine generation were measured. The results observed indicate that, under the experimental conditions, DC represents a more efficient and economical alternative to electrodisinfection than AC.
