4-Step Wastewater Sludge Treatment Process
2018-4-3 The sludge digestion process is a two-phase process. In the first stage, the dry solid sludge is heated and mixed in a closed tank to enable anaerobic digestion by acid-forming bacteria. These bacteria hydrolyze the large molecules of proteins and lipids present in the sludge and break them down into smaller water-soluble molecules, which they then ferment into various fatty acids.

The sludge consistency and appearance is changed through treatment. It must be pointed out that also the heating value of the sludge changes with the way of the treatment. Anaerobic treated sludge has a lower heating value than raw sludge because of sewage gas production. This point has to receive attention by a thermal disposal.

Processes and technologies for sludge treatment
2017-4-20 During the quicklime sludge treatment process, the pH must be kept above 12 for a minimum of 2 hours to ensure the destruction of the pathogens and provide sufficient residual alkalinity for the pH not to fall below 11. This gives sufficient time to store or dispose of the stabilised sludge.
