Process efficiency, influences water matrix

The results described here demonstrate the importance of appropriate treatment and monitoring in actual drinking water processing plants, with attention to the specific requirements of the raw water matrix in use. In particular, the adverse effect of certain processes, namely pre-chlorination, which has been implicated in the inhibition of biodegradation in subsequent steps, and in the formation of alternative metabolites, is highlighted. Furthermore, the variable efficiency of GAC filtration in practice, emphasises the need for regular monitoring and quality control. The duration of specific process steps has also been shown to influence the efficacy of the technique, and should be addressed in application.
