Trihalomethane (THM) formation exceeding the new Dutch drinking water standard has forced surface water treatment plants to abandon breakpoint chlorination. Feasibility of alternatives for primary disinfection, O3 and UV and formation of related byproducts such as bromate, nitrite and assimilable organic carbon (AOC), have been studied. Furthermore, byproduct formation associated with advanced oxidation processes (AOP's) O3/H2 O2 and UV/H2O2 has been studied. AOC, formed in the ozone- and UVbased processes, was reduced effectively by biologically active post-filtration, resulting in biologically stable water. For two drinking water supply companies, bromate formation in the ozone based processes could not be controlled to levels below the Dutch bromate standard (5.0 μg/L, in the case of Evides) or recommendation (0.5 μg/L, in the case of PWN) without compromising the treatment objectives. This paper presents the successful retrofitting of two treatment plants who abandon breakpoint chlorination, consider ozone-based processes, and finally implement UB-based processes.
