Utilization of Pulsed Current-Electro Fenton Technology for the Treatment of Wastewater from Industrial Processes.
In recent years, there has been a rise in the use of electrochemical and advanced oxidation methods to treat the industrial wastewater. The efficiency of several approaches for treating industrial wastewater, including hydrogen peroxide (H2O2), electro-Fenton (EF) and pulsed-electro-Fenton (PEF) processes were all investigated. In evaluation to the H2O2, EF, and PEF technologies, the results showed that the PEF process produced 100 % total color and 98 % chemcial oxygen demand (COD) removal efficiency with a low consumption of power of 3.4 kWhrm-3. The experimental parameters comprised the following: COD - 2500 mg L-1, pH - 3, H2O2 - 300 mg L-1, distance between electrode - 0.75 cm, current - 0.40 A, cycle of pulse duty - 0.75, combination of electrode - Fe/Fe, stirring speed - 500 rpm and treatment duration (TD) - 125 min. It was demonstrated that increasing the TD, current, and H2O2 while lowering the COD content improved the COD elimination efficiency while employing a iron (Fe/Fe) electrode combination with wastewater pH of 3. The efficiency of the EF process has been reduced in comparison to the PEF process because of the development of an impermeable oxide layer on the cathode and the oxidation-induced corrosion on the anode. Consequently, experimental results have indicated that the PEF could be a more promising technology than the EF method for eliminating pollutants from wastewater with reduced power consumption and process efficiency.
期刊介绍：
ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
