40 Google “People Also Ask” Questions

GENERAL STP QUESTIONS

1. What does an STP service provider do?

An STP service provider operates, maintains, repairs, installs, and optimises sewage treatment plants. A professional provider manages biological treatment, aeration, sludge handling, chemical dosing, preventive maintenance, electrical/mechanical troubleshooting, and ensures treated water achieves KSPCB norms for BOD, COD, TSS, pH, turbidity, and faecal coliform. They also offer compliance reporting, AMC services, emergency breakdown support, and STP performance audits.

2. What is included in STP O&M?

STP O&M includes daily process monitoring, equipment operation, and maintenance activities required to keep the plant compliant and functional. This covers DO/MLSS control, sludge removal, diffuser cleaning, pump/blower maintenance, PSF/ACF backwashing, chlorination/UV disinfection, chemical dosing, log sheet recording, testing, troubleshooting, and maintaining consistent effluent quality.

3. How much does STP maintenance cost in Bangalore?

STP maintenance in Bangalore typically costs ₹35,000–₹2,50,000 per month depending on capacity and technology. Costs depend on KLD size, O&M manpower, technology (MBBR, SBR, MBR, ASP), energy consumption, sludge disposal frequency, chemical usage, preventive maintenance needs, and 24×7 shift requirements.

4. What is the best STP technology?

The best STP technology depends on wastewater characteristics, load variation, and space. For apartments, MBBR and SBR work best due to stability and ease of O&M. For hospitals and premium buildings, MBR offers ultra-fine filtration. For industries, a combination of ETP + SBR/MBBR is preferred.

5. Why is STP aeration important?

Aeration provides oxygen to microorganisms that break down organic waste in sewage. Correct DO (2–4 mg/l), uniform air distribution, clean diffusers, and efficient blowers help maintain MLSS, prevent odour, reduce BOD/COD, and sustain stable biological treatment.

6. What is MLSS in STP?

MLSS stands for Mixed Liquor Suspended Solids, the concentration of active biomass in the aeration tank. It indicates biological strength, determines sludge age, affects settling in the clarifier, and directly influences BOD/COD removal efficiency.

7. What is MBBR media?

MBBR media are floating biofilm carriers used to grow microorganisms for biological treatment. They increase surface area, improve BOD/COD reduction, stabilize the system under shock loads, and reduce sludge generation.

8. Why does STP water smell?

STP water smells due to anaerobic conditions and poor aeration. Low DO, excessive sludge accumulation, improper recirculation, choking diffusers, and lack of preventive maintenance often lead to hydrogen sulphide (H₂S) generation causing strong foul odours.

9. What is SBR cycle time?

SBR cycle time is the programmed sequence of Fill–React–Settle–Decant stages in an SBR STP. Typical cycle duration ranges from 3–6 hours depending on inflow, MLSS, organic load, and effluent quality requirements.

10. How does MBR work?

An MBR uses membrane filtration instead of a clarifier to produce ultra-clear, pathogen-free treated water. Membrane modules remove suspended solids, bacteria, and pathogens, making MBR ideal for hospitals, commercial buildings, and water-reuse applications.

APARTMENT-SPECIFIC QUESTIONS

11. Why do apartments need STP?

Apartments need STPs to treat sewage onsite, comply with KSPCB/BWSSB rules, and reuse water for non-potable applications. With Bangalore’s water scarcity, STPs help meet flushing/gardening water needs and prevent lake/groundwater pollution.

12. How to reduce STP odour in housing societies?

Odour can be reduced by improving aeration, removing excess sludge, cleaning diffusers, controlling DO, and using bio-culture. Proper ventilation, periodic pumping, PSF/ACF cleaning, and avoiding anaerobic zones are essential for odour-free STP operation.

13. What causes foaming in apartment STPs?

Foaming is caused by low DO, high F/M ratio, surfactants from detergents, or Nocardia bacteria. Balancing MLSS, adjusting aeration, desludging, and occasional anti-foam treatments resolve the issue.

14. How much sludge should be removed monthly?

Most apartments require sludge removal every 15–45 days depending on tank size, MLSS load, and STP usage. Neglect leads to odour, bulking, poor settling, and non-compliance.

15. How to reuse treated STP water for gardening?

Treated water must meet turbidity, TSS, and pathogen norms before reuse. PSF/ACF polishing, chlorination/UV disinfection, proper storage, and pipeline separation ensure safe gardening reuse.

INDUSTRIAL / ETP QUESTIONS

16. What is industrial effluent treatment?

Industrial effluent treatment removes high-strength pollutants, chemicals, oils, and COD-rich effluents before discharge. It uses equalization, pH correction, coagulation/flocculation, DAF, biological treatment, and tertiary polishing.

17. What is COD in wastewater?

COD (Chemical Oxygen Demand) indicates the amount of oxygen required to oxidize organic and inorganic pollutants. High COD means heavy contamination and requires strong treatment.

18. How to treat high-COD effluent?

High-COD effluent is treated using chemical oxidation, pH correction, coagulation, biological MBBR/SBR treatment, and tertiary filtration. Industries often use DAF/DAF+ systems for heavy loads.

19. What is DAF?

DAF (Dissolved Air Flotation) removes oils, grease, suspended solids, and fats from wastewater. It is essential for food processing, pharma, paint, and chemical industries.

20. What chemicals are used in ETP?

Common ETP chemicals include alum, ferric chloride, lime, caustic, PAC, polyelectrolyte, and oxidizing agents. Selection depends on wastewater characteristics.

HOSPITAL WASTEWATER QUESTIONS

21. Why is MBR used in hospitals?

MBR is used because it removes pathogens, bacteria, viruses, and fine solids more effectively than conventional STPs. It delivers <1 NTU water ideal for reuse and critical safety.

22. How to remove pathogens from wastewater?

Pathogen removal requires membrane filtration (MBR), UV disinfection, chlorination, and proper sludge management. Healthcare STPs must meet strict faecal coliform limits.

23. What are biomedical wastewater norms?

Biomedical wastewater must meet strict biological, chemical, and pathogen standards under KSPCB and CPCB regulations. Parameters include FC <100 MPN, turbidity <1 NTU, and zero harmful pathogens.

24. Can hospital STP water be reused?

Yes, hospital STP water is reusable for landscaping, flushing, and cooling towers if treated to tertiary standards. MBR technology is recommended for maximum safety.

COMPLIANCE & LEGAL QUESTIONS

25. What are KSPCB STP norms?

Key norms are BOD <10 mg/l, COD <50 mg/l, TSS <10 mg/l, pH 6.5–8.5, turbidity <5 NTU, and FC <1000 MPN. Monthly lab reporting is mandatory.

26. What are BWSSB recycling rules?

BWSSB mandates 100% sewage treatment and encourages reuse for flushing, gardening, and cooling towers. Properties must avoid untreated discharge and maintain STP compliance.

27. What are NGT guidelines for apartments?

NGT mandates functioning STPs, periodic audits, sludge management, and no untreated wastewater discharge. Non-compliance attracts penalties and legal notices.

28. How to avoid STP penalties?

Maintain proper O&M, conduct monthly tests, follow SOPs, desludge regularly, monitor DO/MLSS, and keep compliance logs ready. Professional STP O&M prevents penalties.

INSTALLATION & COMMISSIONING

29. What is STP commissioning?

Commissioning is the process of starting up a new STP, stabilising biomass, and achieving compliant treated water. It includes mechanical checks, electrical setup, bio-culture seeding, and performance testing.

30. How long does STP start-up take?

STP start-up takes 7–21 days depending on technology, organic load, MLSS build-up, and environmental conditions. Biological seeding and aeration efficiency are key factors.

31. What is bio-culture dosing?

Bio-culture dosing introduces beneficial microbes into the aeration tank to accelerate biological treatment. It helps achieve stable MLSS, improves BOD/COD reduction, and prevents odour.

32. What documents are required for STP handover?

Documents include GA drawings, P&ID, load calculations, O&M manuals, commissioning report, performance test reports, and compliance certificates.

TROUBLESHOOTING & MAINTENANCE

33. Why does STP generate foam?

Foam is caused by surfactants, low DO, young sludge, or Nocardia bacteria. Adjusting aeration, sludge age, and adding bio-culture helps resolve foaming.

34. What causes sludge bulking?

Sludge bulking occurs when filamentous bacteria dominate due to poor aeration, nutrient imbalance, or high F/M ratio. SVI monitoring and WAS adjustments fix bulking.

35. Why does the blower overheat?

Blowers overheat due to clogged filters, poor ventilation, worn bearings, wrong pressure settings, or electrical faults. Regular preventive maintenance is essential.

36. What causes clarifier overflow?

Clarifier overflow happens due to high sludge blanket level, bulking sludge, hydraulic overload, or faulty sludge pumps. Sludge removal and SVI correction are required.

ADVANCED / TECHNICAL QUESTIONS

37. What is SVI?

SVI (Sludge Volume Index) shows how well sludge settles in the clarifier. High SVI indicates bulking; low SVI indicates dense sludge.

38. What is F/M ratio?

F/M ratio (Food-to-Microorganism ratio) shows the balance between organic load and biomass. It controls sludge age, BOD reduction, and biological stability.

39. What is nitrification in STP?

Nitrification is the microbial conversion of ammonia into nitrite and nitrate. It requires sufficient DO, proper MLSS, and stable temperature.

40. What is membrane fouling?

Membrane fouling is the clogging of MBR membranes due to solids or biological scum. It requires periodic chemical cleaning, backwash cycles, and proper O&M.
