INTERMITTENTLY DECANTED AERATED LAGOONS -IMPROVING NITROGEN REMOVAL

摘要

Intermittently decanted aerated lagoon (IDAL) is a technology employed to treat municipal wastewater. The technology is characterised by biological carbonaceous and nitrogen removal, while low phosphorus levels, when required, are usually accomplished by addition of chemicals. This paper will focus on improving biological nitrogen reduction, in particular the denitrification process.
