An adaptable solution that makes sense
PONDUS keeps the hydrolysis process simple and affordable – even for smaller plants!
Drastically reducing the overall carbon footprint by minimizing solid waste production, PONDUS enables useful repurposing of biosolids (as fertilizer and carbon source) and methane gas outputs (as renewable energy).
Here’s how it works:
Using caustic soda and hot water to destroy cell membranes of Waste Activated Sludge (WAS), organic acids are released in the process. These organic acids are converted more quickly during the anaerobic digestion process allowing for:
- Increased biogas production by approximately 30%
- Dryer cake solids
- Lower polymer consumption
- Higher digester loading rates
- More efficient mixing and pumping due to lower viscosities
- Reduction of digester foaming
- Optional Class A Biosolids production
This results in lower dewatering and disposal costs. The viscosity of the hydrolyzed sludge is drastically lowered (by up to 80%) allowing for higher digester loading rates, reduced digester foaming, more efficient pumping and digester mixing.
Using the heat from the hydrolysis process to heat the anaerobic digesters, operational costs of the system are further minimized. The system works with hot water between 150 to 170 degrees Fahrenheit under atmospheric pressure.
Kenosha Energy Optimized Resource Recovery Project
New process transforms municipal waste byproducts into energy-independent, eco-friendly solutions for cost-savings.
The Kenosha Energy Optimized Resource Recovery Project is a project of CNP, a wastewater treatment process company and subsidiary of Centrisys Centrifuge Systems, in partnership with Kenosha Water Utility, which operates the wastewater treatment plant in Kenosha, Wisconsin.
The project leverages a combination of new technologies to create a holistic solids handling process that moves the wastewater plant towards energy independence, and yields a lower-volume and eco-friendly biosolid by-product – both of which render cost-effective results. The process is the first-of-its kind in North America.
