Disinfection Byproducts in Rajasthan, India: Are
The implementation of chlorine disinfection in low-income countries reduces the risk of waterborne illness but initiates exposure to disinfection byproducts (DBPs). Like high-income countries, low-income countries typically are adopting regulations focusing on trihalomethanes (THM4) as an indicator of overall DBP exposure.

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)
Disinfection Byproducts Treatment Options And Challenges
Regulated and emerging disinfection byproducts (DBPs) pose several challenges for water suppliers, but there is a variety of cost-effective cures. Most public water suppliers are interested in findings ways to comply with existing regulation on disinfection byproducts (DBPs) at minimal treatment cost. The Stage-2 DBP Rule is pushing water
- 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 global disinfection by-products (DBP) regulations?
- This study provides an overview of global disinfection by-products (DBP) regulations and lists current DBP standards of 166 countries with total trihalomethanes (TTHM), haloacetic acids (HAAs), and chlorine residual being the most widely regulated water quality parameters in the world.
- Why is water disinfection important in India?
- Among those, the disinfection of drinking water is considered a necessary and important step as it controls the microbial population. Chlorination is the most practiced (greater than 80%) disinfection process in India, and it is known to generate various disinfection byproducts (DBPs).
- How are DBP guidelines derived in India?
- Similarly in India, the up-gradation of DBP guidelines for THMs has been derived with reference from European Union (EU) Directives (80/778/EEC), United States Environmental Protection Agency (U.S.EPA) standard (816-F-02-013), and WHO water quality guidelines (3rd edition Volume 1) ( IS, 2012b ).
- Is chlorine a good disinfection treatment in India?
- Chlorination is a widely used disinfection treatment in India. Proper optimization of chlorine dosage is lacking in many water treatment plants (WTPs). The governmental program acts as a forum to identify hotspots of microbial contamination. In drinking water, trihalomethanes are the only regulated DBPs.
- Which disinfection method is used in India?
- Chlorine-based chemicals, ozone, and hydrogen peroxide are used as disinfecting agents ( Venkatasubramanian et al., 2021 ). The physical method includes UV or solar light irradiation and filtration. Chlorination is the commonly used disinfection methodology in India rather than ozone and UV irradiation ( Tak et al., 2020 ).
