Chemical-free deposition of magnetic particles from liquid process media

Initial situation:

In the iron, steel and metal processing industry, the input of metallic particles (for example, scale) into various cycles (cooling / gas washing water, emulsions, quenching baths) occurs as a result of production. The removal of the metallic particles takes place in settling basins and, for example, in cooling waters in downstream sand filters using flocculation aids. In this case, a low-concentration thin sludge is produced which has to be further de-watered and cost-intensive to be disposed of. Disposal of valuable materials (iron, alloying elements) is lost.


  • Selective deposition of magnetizable particles, in particular <10 μm
  • Degrees of separation> 90% for different material grades and scale sizes
  • Closure of material cycles by metallurgical utilization of the valuable substances

Our portfolio:

  • Determination of the necessary capacity of the magnetic separation with respect to the criteria of separation efficiency and deposition capacity
  • Check the height of the factor of the concentration of the particles and compare to standard methods such as sand filtration
  • Presentation of the resulting sludge volume flow and its further treatment
  • Determination of the necessary lower surface requirement for magnetic separation
