Waste Recovery
AEROTHERM™
Hydrolysis & hygienization for sludge management
The foundation technology of UTB for sludge management, turning waste into value.
How it works
AEROTHERM™ leverages high-efficiency thermal processes to recover valuable resources from wastewater biosolids. By applying controlled heat, it enhances the breakdown of organic matter through hydrolysis and ensures thorough hygienization by eliminating pathogens. The process improves nutrient recovery, reduces sludge volume, and converts waste into usable energy and reusable water, an advanced, sustainable solution for modern wastewater management.
Advantages
- Reduced disposal costs
- 15–25% energy recovery
- Carbon for denitrification / P-removal
- Liquid fertilizer as a product
- Reduction in volume and mass
- Smaller post-anaerobic digesters with greater efficiency
