Abstract

The invention relates to a process for the regeneration of non-polar, adsorbing zeolites used for the treatment of contaminated water, characterized in that the regeneration is carried out at temperatures ranging from 250 to 350°C, for a time ranging from 0.5 to 1.5 hours, in the presence of an air flow ranging from 150 to 250 m3/hr.
