The Use Of Ozone For Sewage Water Treatment

Sewage water cannot be dumped in any other water, like a river, lake or sea, and also it cannot be disposed of on any land. That is why sewage water is a dangerous hazard that cannot be disposed of in any other water. A minimal dosage of ozone does this job in sewage water treatment better than high concentrations of chlorine in the treatment of sewage water, which is the only solution to treat sewage water. Irrigation, gardening, flushing, and irrigation can all be done using ozone treated water. Ozone treated water is environmentally friendly for disposal.

Ozone Generator for Sewage

Ozone For Sewage Water Treatment

There is an issue with foul smelling odors being generated by sewage plants, especially when they are inside enclosed spaces. There is no doubt that odor pollution from these facilities is the most common complaint they receive from local residents and the greatest problem they have to deal with.

Over the years, many studies have confirmed that ozone treatment is a technically effective method for deodorizing odiferous gases. Thousands of ozone installations have been built to treat the odors associated with sewage plants over the past twenty-five years. Odor-causing compounds are quickly broken down by ozone, one of the strongest oxidants.

The oxidation of malodorous substances by Ozone releases products with improved olfactory characteristics, therefore eliminating odor. Sulphides, mercaptans, amines, phenols, and similar chemicals are among many contaminants that ozone can effectively remove. Aside from that, ozone is highly effective at killing airborne bacteria.

It is unsafe to dispose of septic waste, whether it is municipal or colonial, in any other body of water. Once septic waste has been disposed of, it cannot be dumped in the soil. The waste can even contaminate land or water, which is a serious health hazard to the community. The chemicals in this wastewater are toxic and will cause severe environmental degradation because some of them are not biodegradable. It is imperative that this wastewater be treated before disposal. The treatment generally involves particles being removed and then oxidized in a bioreactor. Further disinfection must be performed.

Ozone For Sewage Water Treatment

Water recycling from sewage treatment plants has increased in sophistication in recent years. As part of advanced sewage treatment, ozone is considered extremely efficient at decolorizing, disinfecting, deodorizing, and reducing COD due to its strong oxidizing capabilities.

By using an efficient ozone generator that has a completely new concept of achieving low running cost and space saving, the users can effectively deal with sewage water treatment.

Diverse sewage treatment processes treat sewage to reduce biological oxygen demand and remove nutrients that could have eutrophicating effects on receiving waters.

Chemical, physical, or biological removal of other components, such as heavy metals, nitrogen, and phosphates (tertiary treatment); and disinfection to eliminate potentially pathogenic microorganisms may also be involved in sewage treatment.

There is a final treatment stage (tertiary treatment) prior to discharge into the receiving environment (such as the sea, river, lake, or ground). In any treatment plant, there may be more than one tertiary process. The final process is always disinfection. Effluent polishing is the name of this process.


  • Water is disinfected thoroughly by Ozone against microorganisms like bacteria, algae, fungi, virus, etc.
  • BOD and COD reduce dramatically when treated with ozone
  • Debris removal and removal of inorganic matter
  • Decantation improvement using flocculation / coagulation
  • On-site ozone production avoids the storage of hazardous chemicals
  • Oxidation of metals and nonmetals including iron, manganese, arsenic, hydrogen sulfide, and organic matter
  • The device does not require refilling, replacements or maintenance

A tertiary sewage treatment system can benefit significantly from the use of ozone. After primary treatment, which is primarily the formation of colloidal particles and the removal of suspended solids and these particles. Secondary treatment is usually done in a bioreactor, where aerobic bacteria are used to oxidize the pollutants. Today, chlorine, which has been used until now to disinfect the water, is the least desirable chemical to use. The ozone is a powerful disinfectant that reduces odors, colors and gives further reductions of color and odor. Moreover, ozone can reduce BOD (biologically derived oxygen demand) and COD (chemical derived oxygen demand). During the tertiary treatment process, ozone is used primarily to disinfect. A low dose of ozone is more effective than a high dose of chlorine in this respect. Odors cannot be emitted from ozone treated water. The ozone treated sewage water is used in many housing colonies for toilet flushing and gardening, as well as for cooling tower water.

Ozone Disinfection

Ozone For Sewage Water Treatment

The following advantages of Ozone disinfection may help you to save Mother Nature over previous methods of chlorine disinfection.

  • Bacteria and viruses are destroyed by ozone in a safe and effective manner.
  • With sufficient concentrations of ozone, the odor and color of the treated waste water can be eliminated or greatly reduced.
  • On-premises ozone production occurs. This does not involve any transportation, storage, or procurement.
  • With organic residues, chlorine forms toxic compounds, such as chloramine, chloroform, and trihalomethanes, which are toxic to the ecosystem. The organic molecules will be oxidized into CO2 and H2O when the ozone reacts with the organic residue.
  • Water treated with ozone grows in dissolved oxygen which has a positive impact on the ecology.
  • Among the most powerful oxidizing agents, ozone is the safest. Ozone may also be referred to as “enriched oxygen” or “activated oxygen”.
  • Studies have proven that Ozone destroys bacteria and viruses 3000 times more efficiently than chlorine when both are present at the same concentration. By exposing E. coli to ozone of 1 mg/l (1 ppm) for 15 seconds, it is destroyed.
  • By using ozone to remove the bad smell from the waste water, waste water can be used in the garden or for flushing toilets.
