Effect UV irradiation and ozonation(O3) process for degradation of copper from electroplating wastewater

Abstract

Copper (Cu) is one of the most common pollutant of the plating industrial wastewater. UV irradiation and ozonation (O3) treatment will enhance reduction of heavy metals pollutans in electroplating wastewater such as copper (Cu). This research intended to study the performance of degradation of Cu using UV irradiation and ozonation (O3) treatment. The research uses variable proses are the intensity of UV irradiation and the ozon flowrate. UV irradiation equipped with UV-lamp tube (8 W, 16 W and 24 W). Ozonation process was carried out at different flowrate (3 L.min-1, 5 L.min-1 and 7 L.min-1). Experiment was done at room temperature and initial pH reaction adjusted at pH 8. Synthetic copper wastewater was prepared at the initial concentration of 150 mg.L-1. The reduction of Cu concentration was analyzed using Atomic Absorption Spectroscopy (AAS). The results of this research showed that treatment of UV and O3 have significant effect for degradation of copper pollutant. The treatment of UV irradiation and ozonation (O3) reduced of Cu contaminant until 48.9% and 66 %, respectively after 60 min of reaction.Copper (Cu) is one of the most common pollutant of the plating industrial wastewater.
