Disinfection Byproducts Analysis | Thermo Fisher Scientific - US
Disinfection byproducts (DBPs) are produced when disinfectants, such as chlorine, chloramines, chlorine dioxide, and ozone, react with inorganic or organic matter. Common DBPs produced in drinking water include chlorate, chlorite, bromate, trihalomethanes (THMs), and haloacetic acids. Receive updates Join community

Disinfection Byproducts (DBPs) | The Water Research Foundation Back to Topic List Disinfection Byproducts (DBPs) The use of strong oxidants to disinfect water has virtually eliminated waterborne diseases like typhoid, cholera, and dysentery in developed countries.
Disinfection By-products (DBPs) Factsheet | National
Disinfection By-products (DBPs) Factsheet. 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.
Disinfection Byproduct - an overview | ScienceDirect Topics
Chlorine and Disinfection Byproducts —The chlorine dosage and free residual chlorine are critical performance parameters. The optimum amount of disinfecting agent is required to achieve appropriate disinfection and minimize DBP formation. The MCL for total trihalomethanes is 0.080 ppb and for haloacetic acids is 0.060 ppb.
Optimization to Reduce Disinfection Byproducts (DBPs)
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.
- 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.
- What are disinfection byproducts?
- Disinfection byproducts (DBPs) are a family of secondary contaminants generated during water disinfection. They are formed by the unintended reactions of chemical disinfectants with certain water matrix constituents, known as DBP precursors (e.g., natural organic matter (NOM), anthropogenic contaminants, and halides) , .
- 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.
- Are disinfection byproducts toxic?
- Disinfection byproducts (DBPs) formed during the disinfection of water have drawn significant public concern owing to their diverse toxicities. In this study, a database of 6310 DBPs reported since 1974 was constructed.
- 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.)).
- 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.
