Oil-water emulsion is used in the metal industry for lubrication, cooling, removal of solid particles from the processes, etc. It is consumed in large quantities, and it can pose a serious ecological problem as wastewater if it is not properly treated before its discharge into the environment.
In this thesis, I compared two methods of processing waste oil-water emulsion with the aim of reducing final waste's volume as efficiently as possible. For comparison, I chose vacuum evaporation and the combined method of flocculation and Fenton oxidation. As criteria of the efficiency of the methods, I chose the value of chemical demand for oxygen in the obtained aqueous phase and calculated volume yield in each process. The vacuum evaporation method proved to be more effective and more suitable for use on industrial scale.
