Treść
Environmental requirements, increasing costs, and water usage are generating the need for closed water cycles in the production processes and for reclaiming water from sewage. Activities in this regard also include the emulsion fluids used in subtractive machining processes used as mixtures with 90–98 percent water. This article presents a method for recycling waste cutting fluids consisting in separating of the oil/water emulsion and treating the water to the level that will allow its reusing for technical purposes. The waste emulsion fluids that had been used in subtractive steel machining were subjected to testing after coagulation, barrier filtration, adsorption, and aeration. The subsequent processes were carried out using the developed device. The changes between the physicochemical properties of the cutting fluid and the reclaimed water phase were determined to reflect the effectiveness of the processes. The reclaimed water was subjected to a detailed analysis of its physicochemical properties, which would consequently determine its suitability for reuse for the manufacturing of cutting fluid. It was found that, as a result of destabilization processes and wastewater treatment, the reclaimed water properties that allow its reuse for technological purposes were restored. The method and the device can be used in the metal industry.
