Thermal Hydrolysis is the pre-treatment that overcomes the main limitation of existing anaerobic digestions: the hydrolysis step. This results in a more biodegradable organic waste that yields more biogas.
At the same time, it reduces sludge volumes and cuts handling costs. The resulting high-quality biosolids, instead of going to disposal, are suitable for fertilizer usage in food production.
The hydrolyzed, low-viscosity material, enables anaerobic digester loading rates to be doubled, debottlenecking existing plants and resulting in capital expenditure avoidance.
TH4+, the Thermal Hydrolysis for +, is the technology featuring super-quick heating that allows higher hydrolysis temperatures without harmful secondary reactions. This enables higher pressures and stronger flashes, more severely breaking the organic waste´s cell structure and making it easier to digest.
Its innovative design avoids the use of pumps, with subsequent gains in process reliability and maintenance cost. TH4+ redefines thermal hydrolysis as a continuous process that overcomes the issues associated with batch processing.
Heat-integrated for greater energy efficiency and with a compact design, it is the state-of-the-art technology to help you squeeze more out of your sludge.
