Ozone in Municipal Wastewater Treatment

Municipal sewage treatment plants face increasing pressure to meet stricter discharge standards while handling growing urban wastewater volumes. An ozone generator for municipal sewage treatment provides advanced oxidation that removes micropollutants, pathogens, and organic matter beyond what conventional biological treatment can achieve.

Key Applications in Municipal Treatment

• Tertiary treatment: removes trace organic compounds and micropollutants

• Disinfection: destroys bacteria and viruses before discharge

• Odor control: eliminates H2S and other foul odors

• Color removal: oxidizes organic dyes and humic substances

• Sludge reduction: improves sludge dewatering characteristics

Ozone vs UV and Chlorine in Municipal Treatment

Chlorine: Creates carcinogenic DBPs, residual toxicity, ineffective against Cryptosporidium.

UV: No DBPs but no residual protection, high energy cost, requires clear water.

Ozone: No harmful DBPs, destroys Cryptosporidium, improves water clarity, decomposes to oxygen.

System Sizing for Municipal Plants

Small town (10,000 m³/day): 500-2,000g/h ozone system

Medium city (100,000 m³/day): 5,000-20,000g/h

Large metropolis (1,000,000 m³/day): 50,000-200,000g/h

Conclusion

An ozone generator for municipal sewage treatment is essential for modern plants meeting stringent discharge standards. Contact TongLin Technology for customized solutions.
