Oil-water-separation / degreasing bath treatment Treatment of oil-water-emulsions for surface treatment (e.g. pre-treatment of metal parts for ed-paint), recovery companies (e.g. for the treatment of alkaline emulsions for part washing), and so on. Separation of emulgated oil particles and recycling of the cleaned liquid into the degreasing bath Concentration of oil-water-emulsions for disposal Cleaning of the oil-water-mixture for indirect lead-in Principle of this process: Aqueous degreasing baths content a tenside combination, alkalines like soda, caustic soda, phosphate, silicate and further complex molecules. The degreasing bath is loosing its efficiency, when to oil content reaches some g / litre. External pollutions also degrease the degreasing efficiency. By ultrafiltration, the oil content can be separated from the degreasing bath and the oil will be collected in the concentrate. The degreasing bath will be dumped into a buffer tank and then pumped in the working tank of the

Recovery of acids and acidic rinse waters Additionally to the pickling bath treatment by microfiltration and ultrafiltration, the recovery of acid becomes more and more important. Additionally to sulphuric and hydrochloric acid, also mixed acids (HF / HNO3) can be recovered. The first step of the acid recovery is mostly a sludge separation by microfiltration. Downstream, diffusion dialysis, electrodialysis or nanofiltration is used for metal separation. For the treatment of rinse waters, OSMO Membrane Systems GmbH offers reverse osmosis or electrodialysis plants.
