Disinfection By-products (DBPs) Factsheet | National
Disinfection by-products (DBPs) are formed when disinfectants like chlorine interact with natural organic materials in water, such as in chlorinated drinking water and chlorine-treated swimming pools. DBPs can be found in the air during activities such as showering, bathing, dishwashing, and swimming.
Contaminant of the month: Disinfection byproducts (DBPs)
Disinfection byproducts (DBPs) are chemical products generated by disinfectants reacting with organic or inorganic chemicals in the water. The organic precursors are predominantly natural products found mostly in surface waters and measured as "total organic carbon" (TOC) or "dissolved organic carbon" (DOC).

Contaminant Candidate List 5 - CCL 5 | US EPA
The CCL 5 includes 66 chemicals, three chemical groups (per- and polyfluoroalkyl substances (PFAS), cyanotoxins, and disinfection byproducts (DBPs)), and 12 microbes, which were selected from a universe of chemicals used in commerce, pesticides, biological toxins, disinfection byproducts, and waterborne pathogens.
Disinfection Byproducts (DBPs) | The Water Research Foundation
The use of strong oxidants to disinfect water has virtually eliminated waterborne diseases like typhoid, cholera, and dysentery in developed countries. However, research has shown that chlorine interacts with natural organic matter present in water supplies to form regulated and emerging disinfection byproducts (DBPs).
- What are disinfection by-products (DBPs)?
- Disinfection by-products (DBPs) are organic and inorganic compounds resulting from chemical reactions between organic and inorganic substances such as contaminates and chemical treatment disinfection agents, respectively, in water during water disinfection processes.
- How many water samples were sampled in Turkey in 2004?
- A total of 29 surface waters from different regions of Turkey were sampled once a month during 2004. Filtered raw water samples were characterized, chlorinated and the concentrations of disinfection by-products (DBPs) were measured. All waters were low in DOC ranging from 0.91 to 4.42 1. Introduction
- How to control the production of disinfection byproducts?
- There are several solutions to control the production of disinfection byproducts. Reducing the concentration of precursors is an effective way to control the production of DBPs. The main organic precursors are NOM, algal organic matter, and wastewater effluent organic matter.
- Why do disinfection byproducts decrease at high temperatures?
- However, at very high temperatures, the level of some DBPs decreases due to their volatile nature. 3.5. Natural organic matter Natural organic matter, as the main precursor of disinfection byproducts, is an important indicator of DBP production. The molecular features of NOM play an important role in the types of byproducts that are produced.
- Which of the following is an inorganic DBP?
- 2.3. Inorganic Disinfection Byproducts Inorganic DBPs include bromate, chlorite, and chlorate. Bromate is a byproduct of the ozonation process. If the water resource contains bromide ions, the use of ozone as a disinfectant will produce bromate through complex reactions (Aljundi, 2011).
- What is a DBP in drinking water?
- DBPs are present in most drinking water supplies that have been subject to chlorination, chloramination, ozonation, or treatment with chlorine dioxide.
