PONDUS™ Thermal Hydrolysis Process (THP)

PONDUS™, an alkaline process, uses low-grade heat (140 °F to 160 °F) and sodium hydroxide for sludge hydrolysis.

• No heat exchangers needed to cool sludge
• No pressure vessel required
• Saturated steam option for sludge above 7% total solids (TS) or with high viscosity
• Minimal equipment needed: high-efficiency heat exchanger, progressive cavity pumps, reactor operating under atmospheric pressure
• Increase biogas production up to 30%
• Reduce biosolids disposal costs up to 30%
• Reduce polymer consumption at dewatering up to 20%
