There are a lot of complications associated with the ways how any humic form of substance can actually undergo the formation of DBP. This is largely based upon the physical and chemical properties of humus and quality of water including pH, bromide concentration and overall temperature of water. The residual chlorine concentration has conclusively been shown to be one of the important players towards DBP formation. In general terms, HAA formation is supposedly directly related to pH increase. It decreases whenever the pH of the water body increase. However, the effect of temperature has been found to be directly proportional. HAA formation increases with the increase in temperature of water body. However, on the hinder side, higher water temperature also serves as a key for HAA degradation (Agori et al., 2015).
Similarly, bromide ion as mentioned before enhances HAA formation. The chlorinated waters generally contain bromide which is oxidized thereby leading to the formation of hypobromous acid and finally forming brominated DBPs. The higher doses of chlorine will lead to the formation of greater amount of DBPs till the time, and precursors for formation are available in the water body. This thus makes it imperative that if the chlorination process is shifted at a later stage, the DBP formation might decrease. It is due to the fact that the amount of precursor will decrease after the processes of coagulation and flocculation and thus chlorine does not have precursors for further reaction. However, researchers have pointed out that enhanced doses of chlorine dioxide above the dose of 1.5mg/ml significantly decrease the formation of HAA (Wang et al., 2014).
