Membrane Filtration
The DYNO Filter

 

Dynamic Cross Flow Filtration

The dynamic cross flow filtration with the DYNO Filter is a high performance membrane filtration process especially for suspensions with critical separation characteristics like Newtonian flow behaviour, viscous or thixotrope characteristics etc.

 

  • thickening

  • washing

  • clarifying of suspensions

is performed in a continuous operation with permanently high throughput rates.

 

In the DYNO Filter suspensions are concentrated up to the flow limit in only one filtration cycle. In most cases the concentrate is as dry as a firm filter cake and the filtrate is crystal-clear.

Membranes with pore sizes of 0.01 - 1.0 µm (micro filtration) are used as filter media.

For sieve filtration, special multi-layer wire cloths are well proved. Benefits:

  • continuous operation

  • constantly high throughputs

  • hermetic sealed apparatus

  • automatic and self cleaning apparatus

  • cooling or heating during the filtration

  • filtration without air contact

Applications

The most economic results are obtained if the particle diameters are in the range of 0.01 µm to 200 µm. This makes the DYNO Filter suitable for applications in many industries and for the separation of different products like

  • fine minerals

  • inorganic pigments

  • organic pigments

  • numerous products in the pharmaceutical industry

  • numerous products in the biotechnology

  • classification of polymer dispersions.
