arium pro VF

Ultrapure Water System

The Arium pro VF system (Sartorius) has been designed to produce ultrapure water from pretreated drinking water by removing contaminants that are still present in this potable water feed. Production of ultrapure water requires continuous recirculation and a constant water flow rate, which is achieved using a built-in pump system with controlled pressure. The conductivity of the water is measured at the feed water inlet and directly at the downstream port (product water outlet).

The system works with two different cartridges. These are filled with a special active carbon adsorber and mixed-bed ion exchange resins in order to deliver ultrapure water with a low total organic carbon (TOC) content. In addition, the system has an integrated UV lamp that has an oxidizing and bactericidal effect at wavelengths of 185 nm and 254 nm, respectively.

Moreover, the water system has a built-in ultrafilter module used as a crossflow filter. The ultrafilter membrane incorporated in this filter retains colloids, microorganisms, endotoxins, RNA and DNA.

A 0.2 µm final filter installed at the water outlet serves to remove particulates and bacteria during dispensing of the ultrapure water produced.
