Selection Guide

The selection of the right filter paper for the intended technical and industrial separation depends on many different factors. Therefore a closer look into the aims and objectives of the filtration process should be completed before a filtration medium is selected. The following questions will help to find the best filter paper:

  • What is filtered?
  • Which kind of particles are in the solution?
  • What is the size of these particles?
  • What shall be the maximum particle size in the resulting filtrate?
  • What is the pH of the solution?
  • What is the temperature during the filtration process?
  • Can the temperature be increased?
  • What is the viscosity of the solution?
  • What is the pressure during the filtration?
  • Are the paper sheets supported in the filter press?
  • What is the material of this support?
  • How long does the filtration process take?
  • How many grams of particle load per sqm of filter paper are expected?
  • Are there any additional requests on the filter material?

Please see some examples for uses and the best suitable filter paper:

The use of a special filter paper in certain filtration equipment usually requires a specific paper shape. Paper rolls with various width and lengths, filter circles with centre hole, large sheets with exactly positioned holes for the right fitting into a filter press and specific shapes with a flute or with pleats.
All these conversions can be done with our own specific equipment. Please contact us!
