Crossflow filtration with sieve filter for difficult suspensions

Achieve precise separation and recovery in challenging conditions with crossflow filtration, ensuring consistent quality and high purity for high viscosity suspensions and complex mixtures.

Continuously Screens and Separates High Viscosity Suspensions

The BoCross MicroScreen from BOKELA is a dynamic sieve filter designed for handling high viscosity suspensions and challenging separation tasks. Utilizing dynamic crossflow technology, it effectively screens and separates particles with remarkable precision. Ideal for the chemical sector, this equipment supports manufacturers of plastic intermediates, pigments, fillers, and dyes by offering continuous filtration with sharp cut points. Capable of operating under pressures of up to 6 bar and temperatures up to 100°C, it processes complex slurries into particle-free filtrates and highly concentrated retentates. The BoCross MicroScreen features automatic operation and can be seamlessly integrated into existing process automation systems. Its asymmetric metallic filter media permits efficient backwashing, contributing to reduced downtime and maintenance needs. Customizable filter sizes from 0.1 m² to 12 m² allow tailored solutions, supporting diverse production scales.
