UltrafiltratiOn Separation of Sewage Containing Active Dyeing

Basing on the study of liquids separation by capillary-porous polymeric membrane the mathematic model of sewage waters separation process of textile enterprises finishing department containing active dying by ultrafiltration method considering the influence of physical parameters on the mechanism and kinetics of the process of ingredients’ transfer through membrane, accompanied by jelly build up are studied. The model was tested in its adequacy and let calculate concentration of active dying in the separated sewage water depending on resistance of jelly layer. The use of this model let find definitive technologic regime of the process, define basic characteristics both for non-standard and for the established regimes, to choose the definite grade of components’ concentration.
