Abstract

Denitrification in biological reactors has been widely studied, whereas, little is known about denitrification occurring in secondary clarifiers. In this study an attempt was made to study denitrification occurring within a secondary clarifier at the Clark County Sanitation District (CCSD) wastewater treatment plant, Las Vegas. The results obtained from this study showed that denitrification and phosphorus (P) release were occurring within the CCSD clarifiers. Dissolved oxygen (DO) and soluble COD concentrations were found to be the most influencing parameters on denitrification and P-release within the clarifiers. The results also showed that sludge blanket height (SBH), solid flux, and state point analysis can be used as operating tools to control denitrification within the clarifiers.
