Unleash the Power of Anaerobic Digestion

Cambi Thermal Hydrolysis Sludge Pre-treatment

Technology for Enhanced Anaerobic Digestion of Municipal and Industrial Sludge.
Cambi’s Thermal Hydrolysis Process (THP) is a proven and reliable technology that has been used around the world since 1995 in existing and “green field” projects to reduce both disposal quantities and the cost of building and operating digesters.

Cambi THP is a high-pressure steam pre-treatment for anaerobic digestion of municipal and industrial sludge and bio-waste. Applying THP technology results in doubled digester loading, increased biogas production, and a pathogen-free and stabilized biosolids product with increased cake dewaterability. This saves both transport and energy costs, whether applying the end product directly in agriculture or drying it for fertilizer or bio-fuel.

The THP is highly energy-efficient with low operating costs. It also eliminates odour problems associated with the treatment of organic materials. The end product (digestate) – a pathogen free and pasteurized biosolids – can be applied to land directly, composted or dried.

Cambi THP plants can be combined with cogeneration plants, which produce green electricity and provide hot steam for the Thermal Hydrolysis Process. However, the biogas can also be cleaned to be used as vehicle fuel or as a replacement of natural gas.

Cambi’s scope of delivery varies from the core THP to complete turnkey digestion plants. We also offer plant operations & maintenance. The THP plants normally handles sludge from wastewater treatment plants for populations upwards from 150,000, or from approximately 5,000 metric tons/ year of sludge. Cambi’s THP enhanced sludge treatment maximise both flexibility and profitability.
