CeraMem®
CeraMem® Pilot-size Membrane Modules
Pilot-Scale Modules
General industrial PVC pilot system (PMX-Multiop) utilizing pilot-scale membranes; available for pilot trials
Veolia Water Solutions & Technologies routinely performs pilot tests for a variety of applications utilizing CeraMem ceramic membranes.
This new generation of "honeycomb" inorganic membrane modules for microfiltration and ultrafiltration has a variety of abrasion-resistant ceramic membranes applied to silicon carbide monolith supports.
Product features include:
-
Compactness
-
Low life-cycle costs
-
High-temperature processing
-
Chemical inertness
Many industrial plants totaling tens of thousands of square feet of membrane have been sold in several countries around the world using this patented technology in first generation CeraMem® membrane products.
This second generation membrane module incorporates new chemically inert membranes and support monoliths (silicon carbide), featuring superior chemical and mechanical durability.
