Wastewater Treatment Parameters
BOD (Biochemical Oxygen Demand)
- • Measures organic matter content
- • Standard test: 5-day incubation
- • Indicates treatment requirements
- • Used for permit compliance
- • Typical range: 100-300 mg/L
COD (Chemical Oxygen Demand)
- • Measures total organic content
- • Faster test than BOD
- • Includes biodegradable and non-biodegradable
- • Higher values than BOD
- • Typical range: 200-600 mg/L
Nutrient Removal
- • Nitrogen and phosphorus removal
- • Prevents eutrophication
- • Required for discharge permits
- • Biological and chemical processes
- • Target: <10 mg/L TN, <1 mg/L TP
Wastewater Treatment Levels
| Treatment Level | BOD Removal | TSS Removal | Processes |
|---|---|---|---|
| Primary | 25-40% | 50-70% | Screening, Sedimentation |
| Secondary | 85-95% | 85-95% | Biological Treatment |
| Tertiary | 95-99% | 95-99% | Filtration, Disinfection |
| Advanced | 99%+ | 99%+ | Membrane, Advanced Oxidation |
