This slide presentation outlines a study on the use of disinfectant combinations to limit disinfection byproduct (DBP) formation. Project goals included examining advanced treatment technologies and
disinfectant combinations for estuarine supplies to
meet current and future regulations
and to meet water quality goals of water utilities.
Specific objectives included:
evaluate combinations of disinfectants on
estuarine waters to reduce DBP formation; and, evaluate effects of disinfectant combinations on
distribution systems. Pilot and
distribution
system
testing included distribution system testing of
annular reactors and
batch incubations in bottles. Parameters analyzed included:
DBPs - THM4, HAA9; Bromate;
Chlorite, chlorate; NDMA; natural organic matter
(NOM), microbial regrowth -
AOC, BDOC;
HPC, ammonia-oxidizing bacteria (AOB);
ammonia (free and total), nitrite, nitrate; and, NOM. Results are given for: total organic carbon (TOC); UV<sub>254nm</sub>; THM4; HAA8; chlorite and chlorate; bromate; THM4 in ARs; and, HAA8 in ARs. Includes figures.
