Abstract

Micellar-enhanced ultrafiltration(MEUF) is a new technology for the treatment of wastewater containingorganic pollutant. The basic idea is that the surfactant forms micellae when it is added to aqueous streams with aconcentration higher than its critical micellae concentration. Almost all of the organism originally dissolved can besolubilized in the micellae formed by the surfactant. Solution then passes through an ultrafiltration membrane withpores small enough to block micellae passage. So as to achieve the goal of getting rid of the organic pollutant. Theprinciple and influence factor of micellar-enhanced ultrafiltration are introduced in detail, and the problemsexisting in this technology and its developing direction in the future are analysed.
