During down periods or over weekends, add to the beaters a solution made up of 20 lb "Metso" 99 sodium sesquisilicate and 3 lb of slime control agents of the chlorinated phenol or phenol-type organo mercurials, per 1,000 gal of 180'F. water. This solution can be circulated through the entire wet end of the system, including refiners, stock chests, and distribution lines, for 1-2 hr. It is then discharged into the empty white water chest and finally drained.
