Types of Disinfectants Used in Wastewater Treatment
Disinfection is a primary process in wastewater treatment, which involves killing or inactivating disease-causing microorganisms before the treated water is discharged into the environment. Several types of disinfectants are used in wastewater treatment, some of which include:
- Chlorine: Chlorine is a commonly used disinfectant in wastewater treatment. It is cost-effective and can be easily applied in simple, reliable, and automated processes. Chlorine works by penetrating the cell wall of microorganisms and killing them. However, it can also react with other organic matter present in the wastewater, forming harmful byproducts such as chloramines and trihalomethanes.
- Ozone: Ozone is a powerful oxidizing agent that is generated on-site and can be used to disinfect wastewater. It works by destroying the cell membrane of microorganisms. Ozone is an eco-friendly disinfectant, as it does not produce harmful byproducts and leaves no residual disinfectant in the treated water.
- UV-C Light: UV-C light is a non-chemical disinfectant that works by damaging the DNA of microorganisms. It is highly effective in killing bacteria, viruses, and protozoa and does not produce harmful byproducts. However, UV-C light requires a clear water surface to penetrate and does not treat the entire volume of water in the treatment facility.
- Peroxide: Peroxide is a strong oxidizing disinfectant that works by destroying the cell wall and the genetic material of microorganisms. It is an eco-friendly disinfectant that leaves no residual disinfectant in the treated water. Peroxide is used in conjunction with other disinfection processes, such as UV-C light, to improve the efficiency of the overall treatment process.
UV Irradiation in Water Treatment
UV (ultraviolet) irradiation is a method used in water treatment facilities to disinfect treated water. The process involves exposing the water to UV light, which kills or inactivates harmful organisms that may be present in the water. This is done by disrupting the DNA of the microorganisms so that they can no longer reproduce.
UV irradiation is a highly effective method of disinfection and does not require any chemicals to be added to the water. This makes it an environmentally friendly and safe method of water treatment.
- UV irradiation is effective against a wide range of microorganisms, including bacteria, viruses, and parasites.
- The process does not change the taste, odor, or color of the water.
- UV irradiation does not produce any harmful byproducts, as can be the case with other disinfection methods that use chemicals.
Although UV irradiation is a highly effective method of disinfection, it does have its limitations. The process does not remove any physical impurities from the water, so it must be used in conjunction with other methods of water treatment, such as filtration.
At the Kanapaha Wastewater Treatment Facility, UV irradiation is used alongside other disinfection methods to ensure that the treated water meets all state and federal requirements for safe drinking water.
| Advantages of UV irradiation | Disadvantages of UV Irradiation |

Ozone applications in wastewater treatment
The Kanapaha Wastewater Treatment Facility uses a variety of methods to disinfect the treated water before releasing it back into the environment. One of the most effective methods is the use of ozone. Ozone is a powerful oxidant that is highly effective in killing bacteria, viruses, and other microorganisms. It also helps to break down organic compounds and reduce the levels of non-biodegradable pollutants.
- Ozone is produced on-site at the facility using a specialized ozone generator. The generator uses energy to split oxygen molecules into individual atoms, which then recombine with other oxygen molecules to form ozone. The ozone is then injected into the treated water to disinfect it before it is released into the environment.
- Ozone is a very effective disinfectant and can kill a wide range of microorganisms, including bacteria, viruses, and protozoa. It is also effective in reducing the levels of non-biodegradable pollutants, such as pharmaceuticals and personal care products.
- Another advantage of ozone is that it is a relatively fast-acting disinfectant. Unlike chlorine, which can take several hours to disinfect water, ozone can achieve the same level of disinfection in a matter of minutes.
While ozone is highly effective in disinfecting water, it does have some drawbacks. One of the main drawbacks is that it can be expensive to produce. Ozone generators require a lot of energy to produce ozone, which can drive up the cost of water treatment. In addition, the ozone can be corrosive to equipment and can cause damage to pipes and other components over time.
Despite these drawbacks, ozone remains one of the most effective methods for disinfecting water at the Kanapaha Wastewater Treatment Facility. By using ozone, the facility is able to ensure that the treated water is safe for release back into the environment, while also reducing the levels of non-biodegradable pollutants.
| Advantages of Ozone | Disadvantages of Ozone |
|---|---|
| Highly effective in killing bacteria, viruses, and other microorganisms | Expensive to produce |
| Effective in reducing levels of non-biodegradable pollutants | Ozone can be corrosive to equipment and pipes |
| Relatively fast-acting disinfectant |
Overall, the use of ozone in wastewater treatment is an effective way to disinfect water and reduce the levels of non-biodegradable pollutants. While it does have some drawbacks, the benefits of using ozone outweigh the costs in many cases. As technology advances and the cost of producing ozone decreases, it is likely that we will see even more widespread use of this powerful disinfectant in the years to come.
Disinfection byproducts (DBPs) in Water Treatment
Disinfection byproducts (DBPs) are chemicals that are formed when disinfectants used in water treatment react with naturally occurring organic and inorganic matter in the water. The most common disinfectants used in water treatment include chlorine, chloramines, and chlorine dioxide. DBPs can pose health risks when consumed in high concentrations over long periods of time.
- Chlorine DBPs – The most common DBPs associated with chlorination are trihalomethanes (THMs) and haloacetic acids (HAAs). Exposure to high levels of THMs and HAAs have been linked to increased risks of bladder cancer, reproductive issues, and other health problems.
- Chloramine DBPs – Chloramines are less likely to produce THMs and HAAs compared to chlorine, but they can lead to the formation of other DBPs such as nitrosamines and haloacetonitriles. Long-term exposure to high levels of nitrosamines has been linked to an increased risk of stomach and esophageal cancer.
- Chlorine dioxide DBPs – Chlorine dioxide is less commonly used in water treatment compared to chlorine and chloramines. However, it can lead to the formation of chlorite, chlorate, and other DBPs. Chlorite exposure has been linked to anemia and nervous system effects, while chlorate exposure can cause thyroid problems and developmental issues in infants.
Water treatment facilities monitor DBP levels regularly to ensure that they do not exceed health-based guidelines. Some treatment methods, such as using UV disinfection or ozone, can create fewer DBPs compared to chlorine-based disinfection. In addition, water treatment plants can adjust their treatment processes to optimize disinfection and minimize DBP formation.

Advanced oxidation processes (AOPs) in water disinfection
Advanced oxidation processes (AOPs) are cutting-edge technologies used in wastewater treatment to remove pollutants and microorganisms from treated water. AOPs are capable of oxidizing hard-to-degrade organic contaminants and emerging pathogens that traditional disinfection methods are unable to eliminate. These processes leverage free radicals and other strong oxidizing agents to break apart complex organic molecules and destroy any remaining pathogens that could pose a risk to public health.
- Examples of AOPs include:
- Photocatalysis – Using light energy to generate highly reactive species that can destroy organic and microbial pollutants;
- Fenton and Fenton-like reactions – Using iron or copper catalysts to generate hydroxyl radicals that can break down organic pollutants;
- Ozone/UV – Combining ozone with ultraviolet light to form hydroxyl radicals and other reactive species that can destroy microorganisms and organic pollutants;
Unlike chlorine, which can create toxic byproducts when it reacts with organic matter, AOPs do not create harmful byproducts during the oxidation process. As a result, AOPs are becoming increasingly popular in water disinfection since they are environmentally friendly and effective. However, AOPs are also significantly more complex and expensive than conventional treatment methods, which may limit their widespread adoption.
Despite these challenges, AOPs remain an essential tool in water treatment, especially in situations where conventional methods are not effective. Kanapaha Wastewater Treatment Facility uses a combination of these AOPs to ensure that the treated water is safe for human use and does not pose a threat to the environment.
