Regulatory Discharge Norms vs. Raw Influent
| Parameter | Typical Raw Influent | CPCB Discharge Limit | Minimum Reduction | Environmental Impact |
|---|---|---|---|---|
| pH | 6.0 – 8.5 | 6.5 – 8.5 | Buffering / Neutral | Prevents river acidification or heavy metals leaching |
| BOD (Biochemical Oxygen Demand) | 150 – 350 mg/L | ≤ 30 mg/L | > 85% removal | Protects dissolved oxygen in receiving waterbodies |
| COD (Chemical Oxygen Demand) | 300 – 700 mg/L | ≤ 250 mg/L | > 75% removal | Eliminates recalcitrant and toxic organic pollutants |
| TSS (Total Suspended Solids) | 200 – 450 mg/L | ≤ 100 mg/L | > 80% removal | Prevents turbidity, sludge banks, and sunlight blockage |
Parameter Diagnostic Reference
Scientific explanation of laboratory test markers and their biological significance.
pH (6.5 – 8.5)
Indicates acidity or alkalinity. Treated effluent must stay within this neutral band to prevent harm to aquatic life.
BOD (≤ 30 mg/L)
Biochemical Oxygen Demand measures biodegradable organic pollution. Lower values prevent oxygen depletion in rivers.
COD (≤ 250 mg/L)
Chemical Oxygen Demand captures total oxidizable organics and inorganics. High values signal toxic or non-biodegradable loads.
TSS (≤ 100 mg/L)
Total Suspended Solids measures fine particulates. Clarification and filtration ensure clear treated effluent.
MBBR Treatment Flow Architecture
Moving Bed Biofilm Reactor (MBBR) combines high-surface-area suspended carriers with aeration and secondary clarification.
