HUBER Solar Active Dryer SRT

HUBER Sludge Turner SOLSTICE®

Sewage sludge drying with solar energy

  • Sustainable, eco-friendly process
  • Best mixing and aeration of the complete sludge bed
  • Minimised odour development and dust formation due to effective backmixing
  • Optimised evaporation efficiency with low energy consumption
  • Unique combination of sludge turning and transport

The basic principle of the HUBER SRT system is drying of sewage sludge in a glasshouse using the incident solar radiation. What makes the HUBER SRT system special is the HUBER Sludge Turner SOLSTICE®, which performs spreading and granulation of the sludge in the greenhouse and aeration, turning and mixing of the sludge bed.

The sludge feeding options can be adjusted to suit customer-specific requirements. The dewatered sludge can be fed into the greenhouse either manually, i.e. with a wheel loader, or fully automatically by a distribution screw that utilizes the evaporation area optimally.

The dried sludge is discharged either into a trough, or by means of a belt conveyor directly into a container. Since the sludge is fed continuously, also units with a low throughput can be used for sludge dewatering.
