Dynamic cross-flow filtration system capable of high concentration, filtration, and cleaning operations of submicron to nanoparticle sizes, as well as wet classification of single micron particles.
The "BoCross(R) Filter," a cross-flow filtration machine characterized by its unique mechanism that includes stirring blades near the filtration surface, suppresses cake formation on the filtration surface. By using MF and UF membranes as the filtration media, it enables high-speed filtration of submicron to nano-sized particles. The stirring blades forcibly create a cross-flow, allowing for high flux even in high-concentration slurries resembling a paste.

basic information
<Principle> This is a dynamic cross-flow filtration machine capable of high concentration, filtration, and cleaning operations for nanoparticles. It features two types of filters: membrane filtration (BoCross Dynamic) and metal mesh (BoCross MicroScreen), which can be selected according to the purpose. By generating cross-flow (shear stress) of the slurry through an internal stirring mechanism, it maintains a high filtration rate and achieves higher concentration than conventional cross-flow filtration machines. It enables "filtration and high concentration of nanoparticle slurries," "filtration of high-viscosity slurries," "recovery of completely clear filtrate," and "desalting and cleaning from slurry mother liquor." <Features> - Capable of handling high-concentration slurries and high-viscosity slurries - Enables high concentration and advanced cleaning operations for submicron and nanoparticle slurries - Produces clear filtrate without solid particles - Automation of dilution cleaning reduces workload and significantly decreases cleaning water and wastewater - Removal of coarse particles in the micron size range through wet classification using metal filter media - Maximum filtration pressure: 0.6 MPaG - Maximum applicable temperature: 100°C (with proven performance of 200°C for special applications) - Applicable for both continuous and batch processing - Completely sealed operation
