Anaerobic Digestion (AD)
This unit covers the principles and the processes underpinning the
anaerobic digestion [AD] of sewage sludge and other organic
materials such as agricultural and food wastes. It considers feed
materials; the underlying chemistry and biochemistry of the AD
process; the equipment and plant used for AD; biogas generation,
harvesting and utilisation for power generation and combined heat
and power [CHP] processes and the reuse or disposal options for
digestion residues.
The unit also explores the current UK policy of encouraging take
up of AD as part of its overall renewables strategy, and issues
surrounding the application of anaerobically digested stabilised
sewage sludges on agricultural/horticultural land.
Key points covered in the unit include:
- Feed sources for AD including sewage sludge, agricultural
wastes and other organic wastes including food waste and
bioplastics.
- Co-digestion
- Anaerobic digesters - principles of operation,
biomethanisation, the plant and equipment used for AD and methods
for optimising and monitoring the process
- AD outputs including utilising gas production for CHP
- AD residuals and reuse/disposal options including sewage sludge
stabilisation and application to agricultural/horticultural
land
