Disinfection Byproducts (DBPs) | The Water Research Foundation
Disinfection Byproducts (DBPs) The use of strong oxidants to disinfect water has virtually eliminated waterborne diseases like typhoid, cholera, and dysentery in developed countries.
Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts
MDBPs are a series of interrelated regulations that address risks from microbial pathogens and disinfectants/disinfection byproducts. The Stage 2 DBPR improves on public health protection by limiting exposure to Disinfection Byproducts (DBPs), specifically: Total trihalomethanes (TTHM), and Five haloacetic acids (HAA5)
Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts
The Stage 1 Disinfectants and Disinfection Byproducts Rule (DBPR) reduces drinking water exposure to disinfection byproducts. The Rule applies to community water systems and non-transient non-community systems, including those serving fewer than 10,000 people that add a disinfectant to the drinking water during any part of the treatment process.
Treatment and Control of Contaminants Research | US EPA
Disinfection Byproducts EPA is researching effective management of DBPs in distribution and premise plumbing systems while effectively reducing opportunistic premise plumbing pathogens (OPPPs). Researchers use bench scale and computer-simulated approaches to determine effective disinfectant concentrations to treat OPPPs while minimizing 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 does disinfection optimization affect DBP formation?
- Thus, disinfection optimization (disinfectant, dose, and reaction time) plays significant roles in control of DBPs formation as well. FC is the most common disinfectant for water treatment at present, due to its high effectiveness, low cost, and ease of prepare.
- How can a filtration system reduce DBP risks?
- The key approaches identified include advanced oxidation processes (AOPs) such as UV/H 2 O 2 and ozone, which mineralize natural organic matter (NOM) and minimize chemical use and sludge production; membrane-based filtration systems, like reverse osmosis, effectively removing contaminants without chemical disinfectants, reducing DBP risks.
- How to control DBP levels in advanced water treatment?
- Removal of precursors (mainly natural organic matter (NOM)) prior to the disinfection process has been recognized as the ideal strategy to control the DBP levels. Currently, biological activated carbon (BAC) process is a highly recommended and prevalent process for treatment of DBP precursors in advanced water treatment.
- 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 the chemical composition of DBP?
- The chemical compositions of the DBPs are strongly dependent on the disinfectants and the disinfection parameters (dose, contact time, water pH and temperature, etc.) and the source water characteristics (NOM composition, micro-pollutants, and inorganic ions (bromide, iodide, ammonia, etc.)).
