Strategies for mitigating chlorinated disinfection byproducts
Disinfection byproducts (DBPs) in 15 full-scale wastewater plants were assessed. Inactivation step before DBP analyses reduced trihalomethanes and haloacetic acids. Chlorate residues were already present in the raw wastewater. Chlorine (or with UV) promoted DBPs while peracetic acid and/or UV did not.

Reducing Disinfection Byproducts through Optimization Webinar Series The Area-Wide Optimization Program (AWOP) has developed tools and approaches that both parent and consecutive drinking water systems can utilize to reduce DBPs in the water treatment plant and the distribution system.
Management Strategies for Minimising DBPs Formation
The chapter consists of 7 sub-chapter: (1) A general introduction, (2) Formation and health effects of DBPs and related legislation, (3) Control technologies to remove DBP precursors, (4) Alternative disinfectants and optimization of the disinfection process, (5) Improvement of operational conditions in treatment plants and in distribution

To minimize the formation of regulated DBPs and comply with existing regulations, water utilities have increasingly been moving away from chlorine to use alternative disinfectants like chloramine, or installing more advanced and costly treatment processes, such as ozone or granular activated carbon to remove DBP precursors.

- What are disinfection byproducts (DBPs)?
- However, disinfectants such as chlorine, chlorine dioxide, chloramines, and ozone can react with natural organisms in the water or pollutants of human origin, such as halogenated solvents, pharmaceuticals, and pesticides, resulting in the formation of a spectrum of halogenated compounds known as disinfection byproducts (DBPs) .
- How can a disinfection process reduce DBP formation?
- Optimizing the disinfection process to reduce DBP formation Changing the disinfection method is an effective means to control the generation of DBPs. Chlorine is commonly used in disinfection, which will cause the formation of many THMs and HAAs DBPs.
- Can chlorinated disinfection reduce the chemical risks of DBP formation?
- It also showed how the chemical risks of DBP formation could be reduced by changing the chlorinated disinfection technologies to PAA or PAA/UV, particularly if reclaimed water is intended for agricultural irrigation to minimize DBP residues. 1. Introduction
- How can chlorine be used to control the formation of DBPs?
- Chlorine is commonly used in disinfection, which will cause the formation of many THMs and HAAs DBPs. To control the formation of these DBPs, several new processes have been used to replace chlorine disinfection, including chloramine, UV, ozone, ClO 2, and the combined disinfection processes.
- Should disinfectant combinations be optimized?
- Lastly, optimization of disinfectant combinations has been favored as a low-cost option to balance the acute risk posed by pathogens against the chronic risk associated with DBPs. Yet this balance is extremely complex.
- What are iodinated disinfection byproducts (N-DBPs)?
- Nitrogenous disinfection byproducts (N-DBPs) and iodinated disinfection byproducts (I-DBPs) are becoming increasingly concerning in water treatment. Among N-DBPs, halogenated types like HANs, HNMs, and HAcAms have attracted attention due to reports indicating their higher toxicity compared to regulated DBPs.
