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.
