intoDBP has released a new publication ‘Upgrading water treatment trains to comply with the disinfection by-products standards introduced by the Directive (EU) 2020/2184′ on the ScienceDirect official website.

The recent EU Drinking Water Directive (2020/2184) has introduced stringent standards for new disinfection by-products (DBPs) such as haloacetic acids, chlorite, and chlorate, in addition to existing regulations for trihalomethanes and bromate. To meet these new requirements, water treatment plants (WTPs) must consider upgrading their processes.

The publication explores strategies for enhancing conventional WTPs to minimize the formation of these regulated DBPs. Three key strategies are identified:

  1. Enhanced Precursor Removal: Improving the removal of natural organic matter, which acts as a precursor for DBP formation.
  2. Alternative Disinfection/Preoxidation: Exploring alternative disinfection and preoxidation methods that reduce DBP formation, such as using ultraviolet (UV) light or ozone.
  3. Removal of Already-Formed DBP: Implementing advanced treatment techniques to remove DBPs after formation, including activated carbon adsorption or membrane filtration.
