摘要: The optimized application of micellar-enhanced ultrafiltration (MEUF) in industrial scale requires the ability to develop simulation models. more conventional approach for description relationships between operation conditions like, example, surfactant concentration and separation performance fouling, centers on evaluation overall resistance time-independent concentrations before after membrane. In this paper, a novel is presented. It based averaged permeation fluxes, molar ratio pollutant/surfactant predict efficiency separation. evolution additional generated by deposition membrane described as sequence of: maximum initial due gelification; decrease resistance, apparently connected with deformation gel permeating flux; an aging effect. observed that different pollutants have effects its evolution. case phenol, higher causes increase resistance. does not seem effect rate.
