Crossflow filtration for microfine to nanoscale suspensions
In many industries, dealing with microfine or nanoscale suspensions poses significant challenges. Traditional filtration methods often struggle with high feed concentrations and viscosity, leading to inefficiencies and prolonged processing times.
Concentrate and filter high-viscosity suspensions
The BoCross Dynamic filter from BOKELA is designed for the dynamic crossflow filtration of microfine to nanoscale suspensions. This filter operates effectively even with high feed concentrations and viscosities, thanks to its dynamic shear gap principle which ensures optimal separation conditions. The system allows for continuous high throughput rates, and unlike conventional crossflow filtration, achieves up to six times higher concentrations. Its modular and hermetically sealed construction supports filter areas from 0.1 m² to 8 m² and can handle operating pressures up to 6 bar and temperatures up to 100 °C. This makes it ideal for applications in plastic intermediates, pigments, fillers and dyes, and pharmaceutical intermediates.
