Membrane Technology in Metal Production Processes
Membrane technology - as a modern and innovative technology - has advanced significantly in the last few years and has established itself as one important step in the manufacturing and processing of metals.
Microfiltration - Ultrafiltration - Nanofiltration
In these processes, microfiltration, ultrafiltration and nanofiltration have developed into state of the art technologies and are being applied worldwide. The filtration methods are effective, save energy and conserve resources while improving quality.
MICRODYN-NADIR products are designed for various pressure-driven membrane processes in crossflow, semi- and dead-end-operation, under “normal” as well as extreme conditions. We supply high quality membranes and modules made from different polymers. Chemical resistance often plays a decisive role when selecting a suitable membrane or module. MICRODYN-NADIR possesses extensive experience regarding the correct selection of membrane and module materials.
Membranes and modules for acid and caustic filtration in complex processes
Microfiltration and nanofiltration are common processes for the separation of particles and heavy metals from process solutions. Because of the chemical and mechanical resistance of MICRODYN-NADIR’s membranes and modules, both MICRODYN tubular modules and SPIRA-CEL® spiral wound modules have proven their worth in these types of application. Precisely because of the extreme chemical resistance even under extreme conditions, high flux rates and high separation efficiency can be realized.
