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

Next Generation Ceramic Membrane Technology

CeraMem® Silicon Carbide Membranes with stainless steel housing

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 membranesand 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 and silica removal from 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
