However, disinfectants can also produce byproducts that are harmful to human health. Therefore, it is necessary to control the formation of disinfection byproducts (DBPs) in water treatment plants.
- The first step in controlling DBPs is to choose an appropriate disinfectant. Chlorine is the most commonly used disinfectant, but it can react with organic matter in water to form DBPs such as trihalomethanes (THMs) and haloacetic acids (HAAs). Other disinfectants, such as chloramines and ozone, produce fewer DBPs.
- The second step is to optimize the dosage of disinfectant. Adding too much disinfectant can increase the formation of DBPs, while adding too little can result in inadequate disinfection. Water treatment operators must strike a balance between disinfection effectiveness and DBP control.
- The third step is to remove precursors of DBPs. Natural organic matter in water is the main precursor of THMs and HAAs. Water treatment plants can use various processes such as coagulation, sedimentation, and activated carbon adsorption to remove these precursors before disinfection.
Water treatment plants also monitor the levels of DBPs in the treated water and adjust the disinfection process as needed to maintain compliance with regulatory standards. For example, the Environmental Protection Agency (EPA) has set maximum contaminant levels (MCLs) for DBPs in drinking water.
Below is a table summarizing the four main DBPs regulated by the EPA and their associated MCLs:
| Disinfection Byproduct | MCL (mg/L) |
|---|---|
| Chloroform | 0.080 |
| Bromodichloromethane | 0.060 |
| Dibromochloromethane | 0.060 |
| Bromoform | 0.080 |
By implementing these measures, water treatment plants can provide safe drinking water while minimizing the risks associated with disinfection byproducts.
