VERFAHREN UND VERBESSERTE VORRICHTUNG ZUM FILTRIEREN MIT TANGENTIELLEM, INSTATIONÄREM FLÜSSIGKEITSSTROM

摘要

Improved process and module (4) for filtration in a liquid medium under tangential flow, according to which the liquid to be filtered is circulated in a nonstationary regime through a circulation loop provided with a filtration module comprising at least one membrane (16), characterised in that the circulation loop comprises a means, in particular a disc rotating in a chamber (6), affecting the flow rate of the liquid to be treated and not its pressure and allowing periodical pseudophysiological flow rates to be generated in the membrane. …Application to microfiltration, ultrafiltration and reverse osmosis. ……
