Cross-flow Filter

Optimized for cross-flow filtration, this high-stability series supports steam sterilization and backwashing, delivering a high-flux, long-life solution for superior industrial separation and environmental compliance.

Specifications and Description

Core Design: Dynamic Equilibrium & High Flux
inopor® ceramic membranes utilize a tubular geometry with an internal active layer for precision separation. By employing cross-flow (tangential) filtration at velocities of 3–5 m/s, the system generates high turbulence that continuously flushes the membrane surface. This creates a dynamic equilibrium of the cake layer, ensuring a clog-resistant process with a consistently high flux rate.

  • Extreme durability and long operating life: Our ceramic membranes are not afraid of strong acids and alkalis, and can withstand extreme high temperatures and abrasive suspended solids. Its operating life far exceeds that of traditional polymeric membranes, significantly reducing the frequency of consumable replacements.
  • Hygiene and low maintenance costs: Featuring bacterial resistance (bioinert), they support high-temperature steam sterilization and are backwashable. When facing severe contamination, you can use strong chemical agents for Clean-In-Place (CIP), and it allows for dry storage directly after cleaning, completely eliminating the need for moisturizing maintenance.
  • Stable and continuous capacity: Cross-flow filtration combined with a closed system design allows for continuous, uninterrupted operation. It can maintain a highly stable flux rate, helping you save massive operational and downtime costs.
  • Wide range of applications: From microfiltration with a pore size of 1100 nm down to cutting-edge nanofiltration reaching a limit of 200 Da, we can provide the corresponding membrane materials to meet your diverse needs—from oil-water separation and fruit juice clarification to highly difficult solvent recovery.
