The aim of this work is to evaluate the use of electrolytes in the breakdown of waste of cutting fluid
emulsion, reusing the recovered phase to develop the reuse in making new cutting fluid, and for the removal of
COD FENTON’s process was used on the fluid which was left before discharging. The different technologies for
different Metal Cutting Fluids (MCFs) were observed and from that which method is effectively suitable for
treatment of different MCFs were selected. Three metal cutting fluids were used to evaluate the comparison by
different methods: Synthetic cutting fluid (water-in-oil), Semi-synthetic cutting fluid(oil-in-water), Mineral oils, all
the MCF’s collected in the emulsified form. The technologies used for recovery of waste oil is Electrocoagulation
and Fenton’s process for removal of COD. The physicochemical properties of these new cutting fluids were close
to the ones of the initial ones, except the viscosity values which increased.
