Development of ceramic membrane

Alsys' expertise allows the development of ceramic membrane. Alsys is a designer and manufacturer of ceramic membranes. We put our historical know-how and our innovative dynamics at the service of your projects. We have a Research & Development center dedicated to the development of ceramic membranes.

Send us your project and we will determine together material best for you: orelis@alsys-group.com



  • To begin with, definition of the size and geometry of the supports: external diameter of 25 mm, or 40.5 mm, feed channel diameters from 2 mm to 6 mm
  • Material development  based on oxide (zirconia, alumina, silica, titanium) for example, or silicon carbide
  • First of all, the steps of the ceramic membrane development  preparation of powders, formulation of materials, shaping (extrusion) and sintering of supports, deposition and sintering of membranes, sol-gel process, hard-coating, zeolite thin film deposition, organometallic, MOF (Metal Organic Framework)
  • In any case, Technical objectives: porosity (porous, semi-dense, dense membrane), mechanical (abrasion) and chemical resistance, surface affinity (hydrophilic, hydrophobic, etc.)


Knowledge and experience

  • 100 different membranes, based on oxide (Kleansep™) or silicon carbide (CeraMem®)
  • 10 tubular and monolith geometries, and 10 cut-off points (MF, UF, NF) 
  • A team of engineers and R&D technicians in materials and chemistry. Laboratories, analysis tools (SEM) and testing tools (furnaces)

Recent activities:

  • New 5 kD and 1 kD nanofiltration membranes
  • New 10 kD ultrafiltration membrane
  • Continuous improvement of 15 kD ultrafiltration (improved abrasion resistance)
  • New 1 µm membrane with mono-dispersed cut-off (to replace  DE filters)
  • 55 channel membrane
  • 40.5 mm diameter
  • Universal laser engraving system with QR code
