Abstract

L'invention porte sur un procédé et un dispositif de production de produits à base de cellulose. Le procédé se décompose en une étape de préparation des pâtes (10) et une étape de formage (14). Une partie de l'eau de traitement (15) provenant de l'étape de formage (14) est recyclée pour l'étape de préparation des pâtes. Afin d'accroître la floculation et par conséquent la rétention des matières qui seraient sinon rejetées comme polluants dans l'eau blanche, on ajoute un agent oxydant, tel que l'ozone, au flux de pâte après l'étape de préparation et avant l'étape de formage. L'ozone a un double effet. Elle rend la floculation plus efficace et agit comme oxydant servant à éliminer les micro-organismes, elle dissout les polluants et blanchit les substances dans le produit final.
