Description
Summary:The development of effective and economic purification methods for the treatment of hydrocarbons contaminated waters is an intensively investigated research area. Especially complicated the purification of stable oil in water emulsions (doil droplets<2 µm). Advanced oxidation processes, membrane separation and their combination are also promising methods. In the present study pre-ozonation combined with membrane microfiltration(PES, dpore=0,2 µm) was applied for the purification of stable oil in water emulsions (coil=100 ppm; doildroplets<2 µm). The effects of applied pressure, stirring speed, time of ozonation and water matrix were also investigated. Fluxes were measured during the experiments, the removal efficiency was determined turbidity and TOC measurements.
