The invention relates to a process for the recovery of fluorinated emulsifier acids from wastewater, which comprises stabilizing the solids which are finely dispersed in the wastewater by means of a nonionic or cationic surfactant or a surface-active substance having an analogous effect and subsequently binding the fluorinated emulsifier acids on an anion-exchange resin and eluting the fluorinated emulsifier acids from this.

L'invention concerne un procédé pour la récupération d'acides émulsifiants fluorés dans de l'eau résiduaire, caractérisé en ce que l'on stabilise les solides finement divisés dans l'eau résiduaire avec un tensioactif non ionique ou cationique ou bien une substance tensioactive à action analogue, on fixe ensuite les acides émulsifiants fluorés sur une résine échangeuse d'anions et on élue à partir de celle-ci les acides émulsifiants fluorés.
