ABSTRACT OF THE DISCLOSURE Described are processes for improving and maintaining the performance of particulate and other types of water-treat- ment solids, especially particulate ion exchange resins, filter media, and adsorbents which have become fouled with organic contaminants, micro-organisms, and wasteproducts thereof. These contaminants are reduced by treating these water-treat- ment solids either batchwise or, preferably, cyclically with a water solution of an effective amount of both a non-ionic sur- factant and a biodispersant.
