Advanced Nutrient Removal & Reclaimed Water Reuse
Florida Class B and Class A Wastewater Treatment Plant Operators typically run larger facilities, many of which discharge to sensitive receiving waters (springs, Outstanding Florida Waters, or coastal estuaries) or produce reclaimed water for beneficial reuse — an area where Florida leads the nation.
Advanced Nutrient Removal
Florida's nutrient-sensitive waters (many with EPA/FDEP-adopted numeric nutrient criteria) drive tighter effluent limits at larger plants. Class B/A operators should understand:
- Biological nutrient removal (BNR) configurations — anoxic/anaerobic zones for denitrification and enhanced biological phosphorus removal.
- How solids retention time (SRT) and dissolved oxygen control affect nitrification/denitrification performance.
- Chemical phosphorus removal (alum or ferric salts) as a supplement or alternative
