Reducing odours throughout the sludge treatment process

The Saphyr™ process, an alternative option to liming, is used to stabilise and sanitise thickened sludge generated by wastewater treatment plants.

  • Reduced evacuation quantities compared to liming;
  • Removal of faecal contamination germs and sporulated forms;
  • Improved dewatering;
  • Subsequent incineration or co-incineration possible;
  • Comparable in costs to liming;
  • Simple design and easy to operate.
