Abstract
Inventia se refera la un procedeu de epurare avansata a apelor uzate provenite de la fabricarea celulozei sulfat, la care, în scopul îndepartarii avansate a substantelor organice din apa, efectueaza dupa decantarea solutiei tratate cu lapte de var, o oxidare catalitica catalitica în prezenta unui catalizator continînd Mn2+ si Cu2+ sub un curent de aer la 130...190 degree C.
