The qualities of sludge generated and the variations in potential processing technologies for pathogen reduction pose a challenge to those evaluating sludge management. Some of the key factors that should be considered when evaluating sludge management options include:
- Land requirements
- Equipment requirements
- Availability of Required additives
- Desired product end use
The extent to which these factors influence the implementation of a particular processing technology will vary, but in all cases, they will influence the cost and application of any of the technologies.
