Drying is the step that turns wet sludge into a manageable raw material. It works at low temperature, and the heat can come from the plant itself.

Why it matters

  • Every extra percent of dry solids means less weight to haul and fewer truck runs.
  • Dried sludge can be stored, which frees the plant from the collection schedule.
  • Without good drying, the thermal step after it works poorly or not at all.
