WAYS TO CLEAN WASTEWATER FROM CHROMIUM
Description
The reason for a chromium problem in this process is the (inevitable) chromium content of all available vanadium raw materials. This work concentrated on investigating the efficiency and behaviour of Al and Fe electrodes in the EC treatment of Cr, existing both separately and simultaneously in model solutions. Several parameters were examined, such as initial metal concentration, iron and aluminum electrode combination, applied current and initial pH of the solution for a treatment period of 180 minutes. Heavy metals exhibited faster removal rates at higher concentrations, but lower residual concentrations were obtained at lower initial concentrations.
