HUBER Solar Active Dryer SRT

HUBER Sludge Turner Solstice®

Sewage sludge drying with solar energy

  • Unique combination of sludge turning and transport
  • Continuous drying process
  • Even distribution of the sludge feed
  • Odourless due to complete restacking of the sludge

The basic principle of the HUBER SRT system is drying of sewage sludge in a glasshouse using the incident solar radiation. A special sludge turning system HUBER Sludge Turner SOLSTICE® performs both spreading and turning of the sludge as well as its transport from one side to the other.

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.
