Diafiltration

Diafiltration is a membrane technical process, in which the solvent and, depending on the application, a part of the ingredients of a solution or a suspension to be replaced. This method is often a classic cross-flow filtration on the back burner because it hardly differs from its technical requirements.

Microfiltration applications

Suspensions, which are contaminated by the manufacturer will be passed in the cross -flow operation in this case over a microfiltration membrane. Feed the template is made up during the process with the same amount of clean liquid is separated as in the filtration. In this way the suspension is purified without the disadvantages of increase in viscosity. The production of high-purity substances is a typical application of this method.

Ultrafiltration applications

Here, high molecular weight constituents of low molecular weight to be replaced in solvent solutions in the same manner, separate, or alter its composition.

Nanofiltration applications

In this way, smaller organic molecules can be shown highly pure. This method is described in the chemical and food industries, is important.

Hemodiafiltration

In hemodiafiltration hemodialysis and hemofiltration are combined. Thus, the pressure-driven and concentration- driven properties of both methods are combined.
