AWWA WQTC62428

The objectives of this slide presentation were to assess the importance of amino acids (AAs) in overall disinfection byproduct (DBP) formation during disinfection with chlorine and chloramines.By using bench-scale treatment of pure solutions of amino acids,the study was able to assess the degree of formation of many DBPsfrom known amino aicds. The experimental design consisted of chlorination/chloramination conditions such as:concentration: 2 mg C/L of amino acids;chlorine dose: 20 mg Cl2/L or NH2Cl/L;pH 7 (buffer solution);Incubation time: 48 hours; and,temperature: 20 ºC.Measurements included:residual chlorine; Trihalomethanes; Haloacetic Acids; Haloketones; and Total Organic Halogen (TOX); and,unknown TOX = TOX-measured DBP. Includes table, figures.
