Next Generation Ceramic Membrane Technology

CeraMem® Silicon Carbide Membranes with stainless steel housing

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 , silicon carbide membranes and support monoliths featuring superior chemical and mechanical durability.

This broad range of aqueous chemical stability will provide improved productivity, due to enhanced cleaning and flux maintenance, for applications involving oily wastewaters including deoiling of oilfield produced water, treatment of desalter bottoms, and the treatment of metal working fluids.

Other features include:

Operation across the full pH range from 0-14
Faster restoration / recovery of flux rates
Increased membrane permeability
