Contact Us About CeraMem® Ceramic Membrane Products
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.
Membrane elements are 34 inches (864 mm) long and 2.6 inches (67mm) in diameter. Membrane area for the 2mm channel is approximately 27 ft.2(2.5m2) and membrane area for the 5mm channel is approximately 11 ft.2 (1.0 m2 ).
