Stabilisation reduces the volatile, putrescible and pathogenic content of sludge before disposal. Anaerobic digestion does so while recovering energy as biogas, increasingly central to energy-neutral treatment.
Digestion converts volatile solids to biogas and stabilised residue, cutting mass and odour.
Time, temperature and process control reduce pathogens to meet biosolids reuse requirements.
Anaerobic digestion captures methane-rich biogas for combined heat and power.
The four-stage pathway, hydrolysis, acidogenesis, acetogenesis and methanogenesis, governs digester performance.
SRT and HRT, with temperature, set volatile-solids destruction and stability.
Operating temperature trades reaction rate and pathogen kill against energy and stability.
Digester performance is benchmarked on volatile-solids (VS) destruction, typically 40 to 60 percent for mesophilic anaerobic digestion, and biogas yield, commonly 0.8 to 1.1 m³ of biogas per kg VS destroyed at roughly 60 to 65 percent methane. These set the energy recovery: the captured methane in combined heat and power can offset much of a plant's energy demand, the basis of the energy-neutral wastewater treatment plant.
Heated, mixed digesters with reliable solids retention and gas capture.
