SEFAR® X-Treme
New high-performance anti-scaling fabric for the Bayer process in alumina security filtration. No scaling after 80+ days. Benefit from stable flow, higher yield and reduced downtime.

No Scaling After 82 Days
After 82 days of operation, SEFAR® X-Treme (left) shows 0% reduction in air permeability, while SEFAR® X-Scale (right) shows 90% reduction of air permeability
Stable Flow, Higher Yield, Less Downtime
Scaling in security filtration clogs fabrics and cuts flow, driving frequent changeouts and downtime. SEFAR® X-Treme is an innovative fabric that resists scaling, keeps flow stable, and protects output. The result is higher productivity and less disruption to your refinery operations.
- Constant flow rate over time (82 days)
- +7% alumina produced in full-scale trials
- 20% longer cloth lifetime
- PFAS-free design
