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
Objectives
- 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)
