DRACO HTC eliminates the sticky phase in sludge dryers, cutting sludge volume by up to 90% and energy use by 70%. Retrofit your dryer for higher efficiency and more biogas.
What is DRACO?
DRACO is BKT’s patented HydroThermal Carbonization (HTC) technology for next-generation sludge treatment. It can reduce sludge volume by as much as 90%, and when paired with anaerobic digestion, it boosts biogas output by more than 30%.
The Sticky Phase Problem
In traditional sludge drying, there is a well-known challenge called the “sticky phase.”
At certain temperature ranges, sludge becomes sticky and adheres to the surface of the dryer, which causes:
- Sudden drops in efficiency
- Frequent maintenance issues
- Higher energy consumption
How DRACO Solves It
DRACO avoids the sticky phase entirely. By retrofitting existing dryers with its innovative process, DRACO ensures:
- Stable dryer operation with minimal downtime
- Up to 70% lower energy use
- Up to 90% sludge volume reduction
- A complete solution to sticky phase issues
Why Choose DRACO?
- Less sludge, more biogas
- Lower energy costs, no sticky phase
- Retrofit existing dryers with ease
- Flexible operation: HTC or THP mode
