ABSTRACT

Formation of trihalomethanes and other disinfection by-products (DBPs) is clearly an issue of supreme importance in the design and operation of potable water treatment plants. 1 3 To date, however, the information on formation of trihalomethanes THMs and other by-products has been presented using empirical correlations of field or laboratory data 4 11 or quasi-mechanistic models with limited verification. 12 , 13 Currently anticipated revisions in the drinking water regulations may necessitate even closer control of DBP formation. 14 The authors have pursued the present research to develop a mechanistically based model of chloroform formation, in the hope that it may form the basis for a more rational design and optimization of water disinfection processes.
