Influence of Chloramine Disinfection on DBPs from Different Organics

Abstract:

A study was made of the influence of chloramination on DBPs formation from different organics based on the grading and clssification of organics.The experimental results show that the formation of CHCl2Br and CHClBr2 are restricted by chloramine disinfection for the hydrophilieity and strong hydrophobicity organics.For the weak hydrophobicity organics,formation of DBAA and CHCl3 is affected.Chloramine disinfection reduces the THMs and HAAs formation from the organics whose molecularities are less than 10 ku,and the influence is weakened to some certain extent with the increase of molecular weight in chloramination.
