Electro-oxidation treatment for turbidity in pistachio processing industry wastewater (PPIW)

Abstract

In this study, it was investigated removal of turbidity from Pistachio Processing Industry Wastewater (PPIW) by electro-oxidation. Electro-oxidation was established using Ti/Pt anodes and stainless steel cathodes in batch mode. Experimental parameters were selected as stirring speed, initial pH value and supporting electrolyte species. Removal fraction and energy consumption was calculated using experimental results of electro-oxidation of PPIW using Ti/Pt DSA type anode and stainless steel cathodes. The highest removal fraction was obtained as 0.85 at pH: 5.3 (natural), no stirring and 0.5 M NaCl supporting electrolyte concentration. Whereas, energy consumption was obtained as 203.5 kW-h/m3 at same experimental conditions.
