DORR Multdigestion System

Advantages attending the use of this time-proved system of two-stage sludge digestion number a dozen or more—have led to several hundred installations, serving many millions of people both here and abroad. Here, however, are the "Big Three” advantages—the major determinants in the continued wide spread selection of a sys­ tem th a t we have maintained in a state of continuous evo­ lution and betterm ent ever since its inception many years ago.
