Crossflow filtration for microfine to nanoscale suspensions
Optimize your production line with advanced crossflow filtration, achieving high solids concentration and clear filtrate even at elevated viscosities. Perfect for handling challenging microfine suspensions, this technology ensures efficient separation and washing processes, streamlining operations while maintaining product integrity.
Concentrates and Clarifies High-Viscosity Suspensions
The BoCross Dynamic from BOKELA offers a cutting-edge solution for filtration challenges in industries such as plastics, pigments, and pharmaceuticals. Utilizing dynamic crossflow technology, this unit excels in concentrating and clarifying high-viscosity suspensions, achieving up to 80 wt.-% concentration levels. Its modular design supports both continuous and batch operations, allowing for high throughput and versatile application. The unique dynamic shear gap principle ensures optimal separation while maintaining flowability even at high concentrations. Operating at pressures up to 6 bar and temperatures up to 100°C, it supports various filter media, including micro and ultrafiltration membranes. The BoCross Dynamic is fully automated, integrates seamlessly into existing production lines, and offers energy efficiency through advanced motor control. Suitable for handling complex materials, it features a hermetically sealed system, ensuring no air contact during processing, making it ideal for sensitive products.
