Thermochemical processes

Thermochemical methods are employed for either significantly reducing the sludge solids content, or pre-treating sludge upstream of anaerobic digestion (AD) to increase the biodegradability of the organic carbon. When operated at elevated temperatures, i.e. for solids destruction rather than for AD pre-treatment, they provide energy recoverable either as heat (for oxidative processes) or a combustible gas or liquid (non-oxidative processes).

Anaerobic digestion optimization through thermal hydrolysis pre-treatment

Pre-treatment of sludge by thermal hydrolysis upstream of anaerobic digestion is used to improve AD efficiency. A study looked at (pre-)commissioning data for a full-scale AD installation undergoing upgrading with TH to assess the basis for optimisation.
