	%X This study presents an investigation of
electrochemical variables and an application of the optimal
parameters in operating a continuous upflow electrocoagulation
reactor in removing dye. Direct red 23, which is azo-based, was used
as a representative of direct dyes. First, a batch mode was employed
to optimize the design parameters: electrode type, electrode distance,
current density and electrocoagulation time. The optimal parameters
were found to be iron anode, distance between electrodes of 8 mm
and current density of 30 A·m-2 with contact time of 5 min. The
performance of the continuous upflow reactor with these parameters
was satisfactory, with >95% color removal and energy consumption
in the order of 0.6-0.7 kWh·m-3.
