Lime and solids dosing

Solids with appropriate properties can be used to supplement lime dosing for sludge stabilisation, reducing the lime dose required.

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.
