The comparison of THMs and HAAs formation and speciation by chlorination and chloramination for different water sources


Sezen Kucukcongar et al. View all

Water Resources Management

Disinfection by-products (DBPs) can be controlled by using alternative disinfectants to chlorine, removing DBPs precursors prior to chlorination and removing DBPs after formed. Chloramine is widely used as an alternative disinfectant to chlorine usage. In this study to evaluate trihalomethanes (THMs...
