Call for Application MPhil: OCCURRENCE, FORMATION, AND TOXICITY OF DISINFECTION BY-PRODUCTS IN DRINKING WATER TREATMENT

Start Date: 1 st January 2023

Duration: 1 year

Venue: Environmental Science Department, KNUST and Laboratoire LaSIRE, Université de Lille, France

Project Summary During drinking water treatment, chemical disinfectants like chlorine are often added at the last and final stage to disinfect the water and maintain a residual concentration in the distribution network. However, the disinfectants may interact with dissolved organic matter to produce undesired disinfection by-products (DBPs), many of which are genotoxic and carcinogenic. The characteristic of Natural Organic Matter (NOM) greatly influences the nature and reactivity of the DBP formed. Increasing anthropogenic activities and shifts in climatic variables such as erratic rainfall patterns and rising temperatures also significantly impact the quantity and quality of dissolved organic carbons in source waters.
