Why Thermal Hydrolysis and Anaerobic Digestion is Rising to the Top in North America

Managing biosolids has become increasingly challenging and costly to wastewater utilities in North America. With the introduction of the thermal hydrolysis process (THP) as a pre-treatment to mesophilic anaerobic digestion (MAD), a new and sometimes cost effective technology alternative has been added to the toolset for biosolids management planning. In recent years, CH2M HILL has conducted biosolids facility plans for clients dispersed throughout North America. These planning efforts included evaluating a wide range of different wastewater residual
processing options. Three case studies are presented to illustrate how THP followed by MAD is rising to the top of technology options selected for long-term biosolids management in North America.
The Biosolids conference attracts the most authoritative global experts in the area of biosolids and organic resource handling, treatment and recycling. The programme covers both the latest innovations and updates of existing technologies. Presentations from respected industry experts and newcomers follow the development of technologies and legislation from inception to full-scale installations.
The conference regularly gathers over 200 delegates from all over Europe, many of them return every year both for the technical presentations and fantastic networking opportunities.
Regular conference themes include:
• Thickening and Dewatering
• Modelling Sludge Handling and Utilisation
• Commissioning and Operating Experiences with Thermal Hydrolysis
• Tackling Potential Odour Problems
• Operating Experiences and Potential Problems in Digester Operation
• Ensuring Optimum Energy Recovery from Biogas
• Liquor Treatment and P Removal
• Alternative Products from Sludge
• Enhancing the Value of Biosolids and Digestate
• Pathogens and Pollutants In Digestate
• Sharing Experiences
