Feralco relies on its experience in the chemistry of aluminium salts to offer products tailored to each configuration of the wet end. 

The aluminium salts contribute significantly to the following functions:

  • sizing: as a component or additive of the sizing system
  • retention of fine material and charge
  • fixing of starch mass
  • capture of contaminating anionic charges
  • white water purification

For each of those functions there is an optimum combination of dosing point and quantity.
