This module provides a practical introduction to anaerobic digestion (AD) covering the process principle, the process operation and its applications for pollution control as well as a mean for renewable energy production from bio-wastes. It considers the feed materials, the underlying chemistry and microbiology of the AD process, factors affecting process performance including process variables, pre-treatments, inhibition and process upsets.
The function and operation of the main equipment are discussed in relation to the performance of the AD process. Options for biogas utilisation, including biogas clean-up and upgrade, are considered along with combined heat and power (CHP) selection for power generation. Factors affecting the use of digested residues in agriculture are covered in the context of the UK regulations and practices.
By the end of this module you will have obtained knowledge of:
Feed sources for AD such as sewage sludge, agricultural wastes and other organic wastes, including food waste and garden waste Co-digestion Anaerobic digesters – principles of operation, the plant and equipment used for AD and methods for optimising and monitoring the process Biogas utilisation including options for gas uses, biogas cleanup and upgrade, and CHP selection The use of digested residuals in agriculture including nutrients and nutrient availability, the Safe Sludge Matrix and risk management with HACCP
