Abstract	During the cutting process, part of the heat generation results from tool-part and chip-tool friction. So that it happens a smaller generation of heat making possible the handling, as well as minimization in the tool deformation, cutting fluids are used, that are the oils base, water or polymeric lubricating solutions, could be synthetic or no, decreasing the attrition coefficient being reduced the amount of heat generated in the process. There is a great variety of cutting fluids that are constituted for several composed as: amines, chlorinated and/or aromatic composed, glycols and nitrosamines besides the presence of metals proceeding of manufacture process, therefore, without a treatment, they cannot be discarded in the conventional sewerage system. At the moment there isn’t a treatment method for the cut fluids in the industries. In that context, intends a study about the viability types of cutting fluids treatment for appropriate disposition. Treatment processes proposed in this work understand acid hydrolysis and Advanced Oxidative Process (AOP), more specifically, Fenton System, in addition proposing a treatment based on the photodegradation (photo-Fenton process). The characterization of fluid before and after treatment it was accomplished by analytical and spectrometry techniques. Oxidative processes were exposed satisfactory for cutting fluids treatment, reducing the levels of pollutants to the allowed by the legislation. Photo-Fenton process was shown more efficient than Fenton process in the oxidation of BTEX and PAHs. Acid hydrolysis processes didn't present satisfactory results, just reducing the metals at the levels allowed for discard.
