BoCross Filter

Filtration

Principle

Dynamic crossflow filtration with the BoCross filter enables high concentration, filtration, washing as application for nano-sized particles. Dynamic membrane filtration (BoCross MicroScreen) and dynamic sieve filtration (BoCross Dynamic) can be selected.
Cross flow (share stress) of the suspension generated by a rotating agitator enables to keep high filtration speed and realizes higher concentration than in case of general cross flow filter.

Features

  • High end-concentrations (like firm filter cakes)
  • High end-concentration and high washing performance for slurry at solid particles>0.01µm
  • High flow rates even with highly concentrated suspensions
  • Filtration for high viscosity slurry
  • Washing, desalination of mother liquor
  • Slimly, jelly smooth particles which are difficult to separate
  • Dead end filtration: absolute clear filtrate
  • Max. filtration pressure: 0.6MPaG
  • Max. operation temp: 100 degree C (normal case), 200 degree C (special case)
  • Continuous operation or batch operation can be selected
  • Hermetically sealed process

Crystallization

This crystallizer can continuously manufacture fine particles (several µm) with a sharp particle size distribution (close to monodispersity).

Filtration

This filter is a continuous vacuum filter which is specialized in high cake washing performance.
