Key Benefits
of Ozone In Sewage Treatment Plants
Powerful Disinfection
- Ozone is 50–100 times more powerful than chlorine and acts 3,000 times faster in killing bacteria and viruses.
- Eliminates >99.99% of pathogens, including E. coli, coliforms, and enteric viruses.
- Effective against chlorine-resistant organisms like Cryptosporidium and Giardia.
Odor Elimination
- Neutralizes hydrogen sulfide (H₂S), ammonia, and other volatile sulfur compounds responsible for foul odor.
- Facilities report up to 90% odor reduction within 24–48 hours of ozone dosing.
Chemical-Free & Eco-Friendly
- Decomposes back into oxygen (O₂) after reaction — leaving no harmful chemical residue.
- Ozone-treated water is safe for reuse in landscaping, construction, or non-potable flushing.
- Supports zero-liquid discharge (ZLD) and circular economy objectives.
Improved Effluent Quality
-
Reduces BOD, COD, and color significantly — essential for regulatory compliance.
COD reduction: Up to 30–50% in tertiary stages.
Color removal: Up to 70–90%, depending on dye load and contact time. - Helps meet CPCB/PCB effluent norms, including newer parameters for emerging contaminants.
Efficient & Fast-Acting
- Requires shorter contact time than chlorine — often less than 5 minutes.
- Compact ozone contact chambers reduce space requirements.
- Lower operating temperatures and no chemical storage required.
Breaks Down Refractory Compounds
- Oxidizes complex organic molecules like phenols, pesticides, pharmaceuticals, and microplastics.
- Enhances AOP (Advanced Oxidation Process) performance when combined with UV or hydrogen peroxide.
Reduced Sludge Volume
- Ozone pre-treatment improves biodegradability and reduces sludge volume by up to 30%.
- Results in lower hauling costs, better dewatering, and reduced sludge management burden.

Go Beyond Compliance: Ozone vs. Conventional STP Solutions
| Feature / Parameter | Prasinos Ozone Technology | Chlorine Disinfection | UV Disinfection | Activated Sludge (Conventional Aeration) |
|---|---|---|---|---|
| Disinfection Efficiency | ✔ Kills 99.99% of bacteria, viruses & protozoa — including chlorine-resistant pathogens | ✔ Kills most pathogens, but less effective on viruses and cysts | ✔ Effective for bacteria & viruses, depends on water clarity | ❌ Not a disinfection method |
| Odor Elimination | ✔ Eliminates H₂S, ammonia & organic odor compounds | ❌ Limited odor control | ❌ Does not address odor issues | ❌ Odors can persist if not managed with post-treatment |
| Residual By-Products | ✔ Leaves no chemical residue — decomposes to oxygen | ❌ Produces harmful by-products (THMs, chloramines) | ✔ Leaves no harmful residues | ❌ Can cause biological sludge buildup |
| Sludge Production | ✔ Reduces sludge through oxidation of organic matter | ❌ May increase bio-sludge | ✔ No sludge | ❌ High sludge generation |
| Energy Efficiency | ✔ Low power usage; no need for blowers or high-pressure pumps | ✔ Low energy, but chemical logistics involved | ❌ High energy use for lamps and cleaning systems | ❌ High energy required for aeration blowers |
| Pathogen Removal in Tertiary Stage | ✔ Highly effective even with varying organic loads | ✔ Depends on dosage accuracy | ❌ Reduced effectiveness in turbid water | ❌ Not suitable for tertiary disinfection |
| Ease of Integration | ✔ Plug-and-play installation in polishing or disinfection tanks | ✔ Simple dosing system | ❌ Requires UV reactors & clear water | ❌ Needs large aeration tanks and long retention time |
| Maintenance & Operations | ✔ Minimal — automated system, no moving parts in contact with water | ✔ Regular chemical handling & dosing required | ❌ High — lamps need cleaning/replacement | ❌ High — blowers, motors, settling tanks require routine work |
| Environmental Safety | ✔ Chemical-free, safe for reuse & discharge | ❌ Environmental risk due to residual chlorine | ✔ Safe if managed correctly | ❌ High energy & resource footprint |
| Suitability for Reuse & ZLD | ✔ Excellent — meets norms for landscape, flushing, construction reuse | ❌ Residual chlorine must be neutralized | ✔ Good, but pre-treatment may be needed | ❌ Requires additional polishing units |
| Operating Cost (OPEX) | 💰 Low — no recurring chemical purchase, low maintenance | 💰 Medium — recurring chemical cost | 💰 High — due to energy and maintenance | 💰 High — energy + sludge disposal costs |

Frequently Asked Questions (FAQs)
1. What is ozone and how does it work in STPs?
Ozone (O₃) is a powerful oxidizing gas used to disinfect and break down contaminants in wastewater. It works by destroying the cell walls of bacteria, viruses, and organic molecules, offering effective, chemical-free treatment.
2. What are the key benefits of using ozone in sewage treatment?
• Powerful disinfection (kills >99.99% of pathogens)
• Odor elimination (neutralizes hydrogen sulfide and ammonia)
• COD/BOD reduction
• Improves effluent color and clarity
• Reduces chemical usage and sludge volume
3. Where is ozone typically applied in an STP?
Ozone is usually used during the tertiary stage of treatment, often just before final discharge. It can also be applied in equalization tanks, aeration basins, or used as part of an advanced oxidation process (AOP).
4. How effective is ozone at killing pathogens?
Ozone is highly effective, eliminating more than 99.99% of bacteria, viruses, and parasites — including chlorine-resistant organisms like Cryptosporidium and Giardia.
5. Can ozone eliminate foul odors from wastewater?
Yes. Ozone breaks down odor-causing compounds like hydrogen sulfide (H₂S) and ammonia, significantly reducing bad smells at and around the treatment plant.
6. Is ozone generation energy-intensive?
Modern systems like Prasinos ozone generators are designed for high efficiency and require much less energy than conventional systems when considering total disinfection output and chemical savings.
7. Does ozone leave any harmful residue?
No. Ozone naturally decomposes into oxygen after it reacts, leaving no harmful by-products or chemical residue in the water.
8. Can ozone reduce BOD and COD levels?
Yes. Ozone oxidizes both organic and inorganic pollutants, resulting in a 30–50% reduction in BOD/COD depending on wastewater quality and contact time.
9. Can ozone systems be retrofitted into existing STPs?
Yes. Prasinos ozone systems are modular, compact, and easy to retrofit into existing plants with minimal civil modifications.
10. How much maintenance do ozone systems require?
Very little. Prasinos systems have no moving parts submerged in water and include automated control panels for monitoring, making them ideal for long-term, low-maintenance operation.
11. How is the dosage of ozone determined?
Dosage is based on plant flow rate, pollutant load (BOD/COD), and target disinfection level. Prasinos designs systems after site assessments or lab-scale validation to ensure the right configuration.
12. Is ozone treatment cost-effective for small STPs?
Yes. Although the initial investment may be higher than chlorine-based systems, ozone offers long-term cost savings through reduced chemical procurement, sludge management, and improved water reuse potential.
