Abstract
The performance of the electrocoagulation process for Phosphates (PO₄) and Silica (SiO₂) removal from synthetic wastewater using Titanium as anode and Stainless Steel as cathode has been studied under some governing operating variables such as initial pH, applied voltage, electrodes inter-spacing and treatment time and at other fixed variables such as temperature, stirring Rpm, electrodes dimensions and the type and amount of the supporting electrolyte.The results showed that the maximum PO₄ removal efficiency of 99.97% after 90 mn. atpH 4.0 and electrodes spacing of 3cm was achieved at applied volts of 12 while the maximum SiO₂ removal efficiency of 31.18% after 90 min. at pH 7.0 and electrodes spacing of 3cm was achieved at applied volts of 12.The results showed also that decreasing the applied voltage drastically dropped the removal efficiency of both PO4 and SiO₂.
