Strategies for DBP minimization

Results of Task 4.1(Strategies for DBPs minimization). Lead: UCT; Contribution: ICRA, SC [M1-6]. This deliverable corresponds to a report summarizing the strategies for minimization of DBPs formation reviewed based on the recent literature, with particular attention to the DBPs regulated by the new DWD and to the emerging DBPs (e.g., NDMA). The identified approaches for DBPs control will include (1) enhanced precursors removal, (2) alternative disinfection and/or pre-oxidation, and (3) removal of DBPs after their formation. Emphasis will be given to the use of alternative pre-oxidation processes that may be easily implemented for the upgrade of water treatment plants and the optimized formation of chloramines for disinfection. Available technologies for upgrading the pre-oxidation units will be evaluated in situ along with the optimal operating parameters.
