Abstract:
Provided are processes of removing particulate fouling from a filtration membrane or for preventing membrane fouling by particulate matter. A process capitalizes on reversal of a naturally occurring diisophoretic particle deposition to actively move particulate material away from a membrane. A process includes placing a microparticle including a salt in proximity to a membrane such that the microparticle creates a gradient generated spontaneous electric field or a gradient generated spontaneous chemiphoretic field in the solvent proximal to the membrane that actively draws charged particles away from the membrane thereby removing charged particulate matter away from the membrane or preventing its deposition.
Abstract:
A process for preparing a composite membrane comprising the steps: a)applying a radiation-curable composition to a porous support; b)irradiating the composition andthereby forming a gutter layer of cured polymer; and c)forming a discriminating layer on the gutter layer; wherein the radiation-curable composition comprises a partially crosslinked, radiation-curable polymer comprising epoxygroups and siloxane groups, a photoinitiator and is substantially free from mono-epoxy compounds. Composite membranes and gas separation cartridges are also claimed.
Abstract:
A membrane filter 26 is disclosed comprising cellulous material 23 allowing the transition of fluid therethrough, and, in a substantially dry state, said membrane comprising also a salt of deoxycholic acid. Optionally, the air side of the membrane (the side facing away from the screen or belt used to manufacture the membrane) faces the sample fluid during use of the membrane. A method of manufacture of the membrane material is disclosed also, employing deoxycholic acid as a surfactant, to improve the recovery rate of the membrane filter in use.
Abstract:
The present invention relates to a preparation method of a hollow fiber membrane for water treatment, wherein the hollow fiber membrane is prepared by preparing a spinning composition comprising a cellulose-based resin, a poor solvent, a plasticizer and an organic solvent, and spinning the spinning composition to a non-solvent. The present invention makes up for shortcomings of conventional preparation methods of a hollow fiber membrane, that is, can easily increase the physical properties of a separator for water treatment, shows easy reproducibility, and can provide a nanofilter (NF) and a reverse osmosis (RO) hollow fiber membrane for water treatment capable of obtaining high efficiency with a low cost.
Abstract:
The invention relates to a process for making porous cross-linked charged cellulosic polymeric membranes capable of binding to a target molecule. The invention provides methods for separating target molecules from other components in a solution comprising use of membranes obtainable by the process of the invention. The method has particular utility in separating proteins and nucleic acids from cell lysates and cultures.
Abstract:
Die vorliegende Erfindung betrifft eine mikroporöse Membran auf Cellulosebasis mit einer porösen Schutzschicht als erster Membranoberfläche und einer porösen Schutzschicht als zweiter Membranoberfläche und einer porösen schwammartigen Struktur zwischen diesen beiden Schutzschichten, wobei die schwammartige Struktur aus zwei isotropen Regionen besteht, und die Poren der ersten isotropen Region, die der ersten Membranoberfläche benachbart ist, kleiner als die Poren in der Schutzschicht, die die erste Membranoberfläche darstellt, aber grösser als die Poren der zweiten isotropen Region sind, und die Poren der zweiten isotropen Region kleiner als die Poren in der Schutzschicht sind, die die zweite Membranoberfläche darstellt. Es wird ein umweltfreundliches Verfahren zur Herstellung einer derartigen Membran offenbart. Die Membranen sind anwendbar in Filtrationsprozessen und zeichnen sich durch hohe Filtrationsleistungen und Filtrationsstandzeiten aus.
