Crystar FT250 25-61-2 offers fine and consistent retention thanks to a 250 nm membrane and a robust carrier geometry with high filtration area.
Crystar® FT Crossflow
Saint Gobain Crystar® FT’s proprietary crossflow technology uses multi-layered membranes of high purity recrystallized silicon carbide (R-SiC) supported by the most permeable carrier in the market, which is also made of porous R-SiC.
The outstanding combination between the superior properties of R-SiC and our compact crossflow geometries elevates the capacities of crossflow membrane filtration processes to new standards.

Exploring the Benefits of Crystar® Crossflow Filtration
Crystar® FT crossflow membranes were developed for the most demanding applications. Thanks to their well-engineered and well-controlled R-SiC microstructure, filtration processes of high value products can be achieved consistently. The carrier geometries were designed with the support of numerical modelling for an optimal combination of filtration fluxes, longitudinal pressure drop and mechanical resistance. To summarise, Crystar® FT crossflow membranes provide:
- Reliable separation processes thanks to the well-engineered and thoroughly controlled multi-layer silicon carbide membrane,
- Low energy consumption resulting from high permeate fluxes at low transmembrane pressures and low recirculation speed,
- Fast and effective CIP cycles enabled by the unmatched thermal shock resistance, thermal stability and corrosion resistance for harsh cleaning operations,
- High compactness thanks to the high filtration area developed in big size tubular carriers combined with high permeate fluxes,
- Efficient backwash operations thanks to high carrier permeability and low adsorption of negatively charged compounds (bacteria, proteins, oils,…).
