ceramic membrane element

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)

Dimensions: 34 inches (864mm) L x 5.6 inches (142mm) diameter. Area is approximately 115 ft.² (10.7m²) for the 2mm channel and 54 ft.² (5.0 m²) for the 5mm channel.
