~ aLuvels of soluble sodium salts in dual alkali sludge (filter cake) depend strongly on the degree of
dike wash. Tlie highest levels shown reflect single measurements on an unwashed dual alkali filter
rake.
1 bLevels of soluble chloride components in sludges are dependent upon the chloride-to-sulfur ratio in
the coal. Tlie liigliest levels shown are single measurements for a western limestone scrubbing sys-
tem operating In a closed-loop using cooling tower blowdown fur process makeup water.
