Electro-oxidation of pistachio processing wastewater using Ti/Pt mesh-type anodes in batch system
Özet
In this study, the treatment of pistachio processing wastewater (PPW) by electrooxidation method was investigated. Ti/Pt-plated electrodes were used for the anode
material, and stainless steel electrodes were used for cathode material. Experimental
studies were carried out in batch mode. Stirring speed, supporting electrolyte species
and concentration, initial pH value, current density, temperature and dilution ratio
were selected as experimental parameters effecting removal efficiency. In Ti/Pt electrode experimental studies on the optimum conditions, chemical oxygen demand
(COD), total organic carbon (TOC) and total phenols (TP) removal efficiencies were
obtained, respectively, as 99.98%, 70.74% and 100%, and energy consumption value
was obtained as 297.5 kW-h/m3 (12.39 kW-h/kg COD, 51.29 kW-h/kg TOC and
64.68 kW-h/kg TP). As a result of the experimental studies, the PPW can be treated
by electro-oxidation. Given the results of removal efficiency and energy consumption
values, it was concluded the electro-oxidation using Ti/Pt anode very appropriate
treatment of PPW.
