Efficient Lead Remediation with Fenton Oxidation in Produced Water

Abstract

Wastewater contains multiple pollutants in different forms that may be biodegradable or non
degradable. Therefore, it was necessary to find different methods and processes to remove these 
pollutants, as Fenton oxidation (FO) processes were commonly used for commercial and residential 
operations. In a glass batch reactor, a Fenton oxidation process was performed for the purpose of 
purifying the produced water (PW) and removing the contaminated lead metal. Depending on the 
batch system used, the effect of operational process variables such as pH, oxidation time and 
concentration of hydrogen peroxide and ferrous sulphate was tested. Through the results obtained, it 
was demonstrated that the possibility of applying Fenton oxidation technology in removing lead 
metal contaminants from the produced water (PW) was successful. Lead elimination of 94.18% was 
achieved when using the Fenton oxidation technique, where a time of 120 minutes was taken at a 
pH of 6.5, 62.5 and 25 ppm for hydrogen and ferrous sulphate concentrations, respectively.
