WhatsApp: 9710035249STP Daily Operation Guidelines
1. Equalization Tank
- Maintain continuous aeration
- Check inlet screen and remove plastics/solids
- pH range: 6.5 – 7.5
2. Aeration Tank (ASP / MBBR / SBR)
- MLSS – 2000 to 3500 mg/L
- Dissolved Oxygen (DO) – 2.5 mg/L minimum
- Blowers should run 24×7
- MBBR media should be 60–65% moving
3. Secondary Clarifier
- Return sludge pump to maintain MLSS
- Sludge blanket level: 10–15%
- Supernatant water should be clear
4. Filter Feed & Pressure Sand Filter
- Backwash daily if turbidity ↑
- Inlet pressure 1–2 kg/cm²
5. Activated Carbon Filter
- Removes colour, smell
- Carbon replace: every 6 months
6. Disinfection
- Sodium Hypochlorite dosage: 2–5 ppm
- Treated water should have no odour
STP Troubleshooting – Common Problems & Solutions
1. Bad Smell / Odour
Cause: Low aeration, blower failure, low DO.
Solution:
Solution:
- Increase blower timing or add extra blower
- Check diffuser choking
- Add bio-culture for 5 days
2. Black / Foamy / Grey Water
Cause: Low MLSS, toxic load.
Solution:
Solution:
- Add fresh sludge from healthy plant
- Reduce inlet load for 24 hours
- Increase aeration
3. Sludge Not Settling
Cause: Bulking / filament bacteria.
Solution:
Solution:
- Add polymer 0.2 ppm
- Chlorinate return sludge line (0.5 ppm)
4. High TDS / Colour
Cause: Chemical waste mixing
Solution:
Solution:
- Install chemical segregation tank
- Add activated carbon
5. Blower / Pump Frequent Failure
- Clean strainers weekly
- Check panel overload relay
- Use proper earthing
