Post-Treatment Options for the Anaerobic Treatment of Domestic Wastewater
This paper focuses on the post-treatment options for the anaerobic treatment of domestic wastewater. Initially, the main limitations of anaerobic systems regarding carbon, nutrients and pathogen removal are presented. In sequence, the advantages of combined anaerobic/aerobic treatment and the main post-treatment options currently in use are discussed, including the presentation of flowsheets and a comparison between various post-treatment systems. Lastly, the paper presents a review of emerging options and possible improvements of current post-treatment alternatives.
