VSEP membrane technology for glycol regeneration through the example of waste airport de-icing fluids (part 2)

Summary

The results of a series of long-term pilot tests of the VSEP technology for vibromembrane separation of waste contaminated solutions of glycol-containing fluids using nanofiltration membranes are presented. The tests were carried out on the basis of one of the research and production companies located in the Central Federal District of Russia. A mixture of waste contaminated solutions of de-icing fluids collected at large airports during the cold season of the year was used as research liquid. He studies have shown positive results, so the technology can be recommended for industrial application. The separation process is stable, and the quality of the effluent meets the most stringent requirements. A feature of the technology under study is its ease of use, the almost complete elimination of chemicals and the compactness of the equipment, which makes it possible to design local systems for the purification of solutions of glycol-containing liquids.
