Full-size ceramic membrane element
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. The membrane elements are extremely compact with up to 230 ft2 membrane area/ft3 (760 m2 membrane area/m3).
Module Range & Specifications - Production Scale Membrane Elements (2mm & 5mm)
