Electrodialysis (ED) is used around the globe in many industrial, laboratory and recycling environments. ED is an industrial membrane separation process in which ions are transported through ion- permeable membranes, from one stream to another, under the influence of a voltage potential gradient.
An electrodialysisunit consists of a package of membranes alternating selectively permeable for cations or anions. The feed and the concentrate flow between these membranes.
Paques develops and produces complete units for the application of electrodialysis, (membrane) electrolysis, diffusiondialysis and membrane filtration.
SnowPure's Excellion ion-exchange membranes are uniquely designed for e-coat paints, electrodialysis (ED), electrochemical separations, deionization processes, and are used in SnowPure’s own electrodeionization (EDI) modules.
Electro-deionization (EDI) is based on the engineering principle of electrodialysis. It is an electrochemical separation process in which ions from a low concentration solution pass through a special membrane to a solution of higher concentration. The activating force is an electric field between cathode and anode.
Application Field: Micro scale feasibility tests of ED applications, Electrodialysis of precious samples, Analytical sample pretreatment.
Recovery of acids and acidic rinse waters; Additionally to the pickling bath treatment by microfiltration and ultrafiltration, the recovery of acid becomes more and more important. Additionally to sulphuric and hydrochloric acid, also mixed acids (HF / HNO3) can be recovered. The first step of the acid recovery is mostly a sludge separation by ...
