ASSESSING THE DBP YIELD - UNIFORM FORMATION CONDITIONS

A new chlorination approach has been developed for assessing disinfect ion by-product (DBP) formation under constant, yet representative cond itions. The rationale used in the development of the uniform formation conditions (UFC) test and the results of a parametric sensitivity ana lysis are presented. Within the acceptable range of conditions, the DB P formation varied by less than 4 percent for the three waters examine d. UFC tests results will allow a direct comparison of DBP formation a mong different waters and allow the evaluation of how treatment change s affect DBP formation in a specific water.
