PONDUS™ Thermal Hydrolysis Process (THP)
PONDUS, an alkaline process, utilizes low grade heat (140 °F to 160 °F) and sodium hydroxide for sludge hydrolysis. A typical PONDUS system consists of a hydrolysis reactor, hot water heat exchanger, chemical dosing station, pumps, instrumentation and controls. PONDUS reduces sludge viscosity, enhances biogas production and improves sludge dewaterability.
PONDUS is designed to utilize low grade heat (from hot water), rather than steam, as a heat source for sludge hydrolysis. A certified steam boiler license is not required to operate the system. PONDUS’ design allows it operate the atmospheric pressure without involving a pressurized vessel. Maintaining PONDUS is easy. Typical maintenance includes: pump maintenance, heat exchanger cleaning, and sodium hydrolyzed refilling.
