Crossflow

Crossflow filtration (also known as tangential filtration), has often been seen as the method of achieving a waste-free filtration. This because a crossflow filter does not require disposable filter media as e.g. filter cartridges or filter bags.

Current Crossflow systems still deal with various issues:

  • very fine (membranes ranging 0.1 to 5 micron)
  • problems with the sealants (pottings)
  • large amounts of rinsing fluid needed when changing from product A to product B In our ARROSEP system, we make use of sintered stainless steel filter tubes in a unique and patented concentric configuration.

In our ARROSEP system, we make use of sintered stainless steel filter tubes in a unique and patented concentric configuration.

Specification:

  • full stainless steel construction (optional Hastelloy)
  • operating temperatures up to 200°C
  • micron ratings ranging from 2 to 100 micron absolute
  • fully automated operation

A pilot test unit is available; it can produce between 300 and 1500 liters/hour filtrate (also called permeate), depending on liquid type, particle concentration and micron rating of the filter elements.For lab applications, we can provide our Mini-CF, this can do 0.1 to 2 liters/minute permeate. Typical applications are; catalyst recovery in synthesis processes, particle classification in dispersions, flaky particles filtration (e.g. graphite, graphene, metal flakes).
