Filter granules

  • Development loose-fill fiber granules using a pull-drill process for selective removal of gas and exhaust air.
  • Optimisation/adaptation of fibre granules to each filtration task  through physical, chemical or biological agents
  • Characterisation of physical-chemical filter-material properties such as bulk density, porosity, flow resistance, adsorption capacity, regenerative capability


Technical equipment



  • Devices for manufacturing long-fiber reinforced granules for use as filter materials
  • Filter stand for determining the pressure differences in  virgin materials exposed to various flow conditions
  • Gas analyses (IR spectrometer, electrochemical sensors)
  • Immersion, spraying and powder coating devices for loading fibre granules
