Abstract

Removal of Phosphorus from Potato Chips Processing Wastewater by Electrocoagulation Process: Comparison of Electrode Material

Abstract

In this study, removal of phosphorus from potato chips processing wastewater by electrocoagulation (EC)
process was investigated by using Al and Fe electrodes. Operating parameters affecting phosphorus
removal efficiency such as pH, current density and electrolysis time were optimized. In the EC model
reactor in which either Al or Fe electrodes were used, the optimum hydraulic retention time was found to
be 40 and 60 min, respectively, while the final pH was found to be 7.85 and 8.15, respectively, and the
current density was found to be 65 A/m2 for both electrode types. In case of using Al and Fe electrodes
under these experimental conditions, the initial total phosphorus concentration of 54.4 mg/L decreased to
10.4 and 5.0 mg/L, respectively, and the initial orthophosphate concentration of 45.3 mg/L decreased to
5.9 and 2.9 mg/L, respectively. Considering the final pH value, it can be pointed out that the resultant
effluent can be discharged without any pH adjustment.
Considering the costs for electrodes, energy and chemical agents, operating costs for the continuous-flow
EC model reactor were found out to be $1.14 and 0.76 per cubic meter wastewater for Al and Fe
electrodes, respectively. It was determined that Fe electrodes are more effective than Al electrodes for the
removal of phosphates from potato chips processing wastewaters, and that the operating costs are lower
when Fe electrodes are used. It has been determined that the orthophosphate and total phosphorus
removal by the EC process is suitable with the second order reaction kinetics.
