Advanced oxidation process efficiency in removal of organic pollutants from metal cutting fluid waste water by the Fenton’s reagent

This article consider the treatment of a kind of emulsion wastewater that is named metal cutting fluids (MCFs) which used as a coolant and lubrication in by different metalworking operations and machinery process Treatment of this kind of wastewater imposes an excessive cost on metalworking industries because of its high COD concentration andnon-biodegradability. The worldwide annual usage is estimated that about 3.8-7.6 million m3 of oilywastewater results annually from the use of MCFs. Some of industries In Iran who consume a large amount of this kind of fluids are Hesa airplane manufactures and severalcar manufacturers like as Iran Khodro Co In this paper, it has been evaluated the effectiveness of Fenton Oxidation Process astreatment method for MCFs wastewater. The study was conducted in a pilot plant Also ensign to previous methods and their results which is used for treatment of cutting fluidwaste water in the world.Fenton Oxidation Process has a more prominent role in the treatment of WCFs because it provides some significant advantages such as easy operation a shorter retention time, cost effectiveness
