Abstract
The present invention is directed to a method of detoxifying water containing a cationic surfactant based biocide. The method comprises adding to an aqueous stream including a biocide containing cationic surfactants a sufficient quantity of a combination including clay and a non surface active sulfonate such as a polymerized alkyl naphthalene sulfonate. The combination allows for a high solids detoxification treatment.
