MLVSS Analysis Guidelines
MLVSS Significance
- • Measures active biomass in treatment
- • Indicates biological activity level
- • Used for process control calculations
- • Helps optimize treatment efficiency
Typical Ranges
- • Mixed Liquor: 1,500-4,000 mg/L
- • Activated Sludge: 2,000-6,000 mg/L
- • Return Sludge: 4,000-12,000 mg/L
- • Waste Sludge: 6,000-15,000 mg/L
