Cambi is the leading global provider of thermal hydrolysis solutions for sewage sludge and organic waste management. Since first trialing the thermal hydrolysis process in the early 1990s, we have become a well-known, trusted technology provider for advanced anaerobic digestion and biogas solutions in wastewater treatment. What is the thermal hydrolysis process? Before wastewater returns to nature, it undergoes several treatment steps to remove organic matter, nutrients, and pollutants. The remaining solids, called sewage sludge, can be processed in an anaerobic digester to stabilize them and produce biogas. By exposing sewage sludge or other types of wet organic waste to high temperature and pressure, the thermal hydrolysis process (THP) simplifies the sludge breakdown before or after anaerobic digestion. Thermal hydrolysis increases biogas production while producing pathogen-free biosolids in much smaller amounts than traditional methods. These biosolids are safe for land application and can be used in thermal processes like drying, pyrolysis, and incineration. Up to 50% higher biogas production Thermal hydrolysis exposes sewage sludge to high temperature and pressure and then breaks the cell walls to increase biogas production by up to 50% during mesophilic anaerobic digestion. The additional biogas can be used for steam production, to generate green electricity, or as replacement for natural gas, including to fuel vehicles. Improved biosolids dewatering Thermal hydrolysis cuts sludge disposal costs by reducing sludge volume. It converts more organic matter to biogas and boosts dewatering efficiency. Less sludge means lower transport and handling costs. Sterilized biosolids are easier to store and handle, and can be used as fertilizer. High-quality biosolids High-temperature and pressure sterilization, followed by steam explosion, destroys pathogens and odorous bacteria after digestion. The resulting Class A biosolids are without pathogen regrowth, low-odour, and meet strict regulations, benefiting both treatment plant workers and nearby communities. Tripling digester throughput When thermal hydrolysis pre-treats sewage sludge, it speeds up the hydrolysis step of the anaerobic digestion process. This boosts digester loading rates and reduces hydraulic retention times, tripling throughput. It minimizes the size of new digestion plants and maximizes the use of existing ones, optimizing assets for all projects. Lower carbon footprint Cambi thermal hydrolysis offers the lowest carbon footprint for all biosolids outlets by enabling smaller facilities with lower embodied carbon, producing lower volumes of final biosolids, using less energy for thermal processing, generating more renewable energy, and providing new disposal routes. Built to last, easy to install Cambi systems are robust, reliable, and designed for maximum availability. The pre-assembled B2 and B6 systems simplify installation and start-up, saving time and effort on site.
