Anaerobic Digestion


The IWA SG on Anaerobic Digestion (AD) is an international forum for activities related to anaerobic conversion processes. The core issues this group is concerned with include the following:

  • Biogas (green energy) production
  • Water treatment and reuse
  • Solid organic waste treatment
  • Recovery of resources
  • Anaerobic microbiology
  • Reactor technology development
  • New wastewater process technologies

The issues above are important for the prevention of water pollution by reducing organic solid waste and wastewater disposal, for saving water by enabling water reuse, for fossil energy saving and hence water saving, and for progressing from water conservation to resource conservation.

Anaerobic technologies are key to enable resource recovery from wastewater and for new water technologies. The one key innovation/technology/development or hot topic on anaerobic digestion that will be transformational in this field is the development of high-rate anaerobic reactor technology that is independent of the presence of granular biomass.
