Saphyr™
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.
Saphyr™ reduces the odours generated by the sludge production process through to its final destination.
Performance
- Long lasting reduction of odours;
- 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.
