Abstract

Background and Objectives: FORMALDEHYDE is a toxic substance and harmful to human beings and the environmental health. Therefore, the effluents containing FORMALDEHYDE have to be efficiently treated before discharging into the environment. This study was aimed at investigating the efficiency of ELECTRO-FENTON (EF) PROCESS in pre-treating INDUSTRIAL WASTEWATER containing high concentrations of FORMALDEHYDE.Materials and Methods: The effect of the important operational variables including pH, current density, H2O2 dosage, and reaction time were evaluated on the degradation of 7500 mg/L FORMALDEHYDE using batch tests. The EFP batch reactor was consisted of a cylindrical glass column with 5.20 cm in internal diameter and 34.50 cm in height. Working volume of the reactor was 500 mL.Results: The maximum FORMALDEHYDE removal was obtained at alkaline pH of 10, H2O2 concentration of 10 mM/min, current intensity 8.5 mA/cm2, and the reaction time of 6 minute. Furthermore, aerating the EFP cell could enhance the FORMALDEHYDE removal. Complete removal of FORMALDEHYDE was obtained under the abovementioned operational conditions.Conclusion: This study demonstrated that the EFP is capable of reducing high concentration of FORMALDEHYDE (7500 mg/l) to the level suitable for biological post-treatment.
