PONDUS — Thermal Hydrolysis Process
A Simple Solution for Sludge Hydrolysis
PONDUS, a thermal/alkaline hydrolysis process, is designed for solids from 4% to 12% and uses a combination of caustic soda (NaOH) and low grade heated water (140 °F to 160 °F) to break down the cell walls.
The passing of the Inflation Reduction Act in late 2022 is a great incentive for facilities to install a biogas process like PONDUS and take advantage of the new Investment Tax Credit (ITC).
No heat exchangers needed to cool sludge after hydrolysis to maintain an optimum digester temperature
No pressure vessel required
Saturated steam option for sludge above 7% total solids (TS) or with high viscosity
Compact, small footprint solution for all sized plants
Typical maintenance includes
