I. Overview of the 2540 roll membrane separation system of microscale ultrafiltration/nanofiltration/reverse osmosis

Small multifunctional 2540 membrane separation system, mainly for ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) separation and purification, for the liquid with water as the solvent can be filtered, decolorized, desalted, purified, concentrated. According to the size of the molecular weight of the separated substance, the selection of the membrane, each membrane can be used alone or can be installed with 3 identical membranes at the same time; It can separate substances ranging from 0.03μm to 100DALTON.

Small multifunctional 2540 membrane experimental equipment can be suitable for almost all 2540 membrane elements, easy to change the film, we recommend the selection of standard membrane elements are imported health food grade products, with wide flow channel, pollution resistance, high temperature (80℃), long service life and other advantages, you can also choose strong acid, alkali membrane elements according to customer needs. The equipment has the advantages of easy cleaning, maintenance and large freedom of use.
