Durco Filters By Ascension Industries - Sludge Dryers

Flo-Dry Enersaver is a two-stage dryer system, where the first stage is a direct fired hot air rotary dryer which dries sludge to 40-45 % dry solids. The partially dried product from the first stage dryer is passed to the final drying in the second stage dryer. The second stage is a belt-type dryer with multiple belts and drying chambers.
