AWWA WQTC65694

Aluminum, as well as turbidity and organic precursors of disinfection byproducts (DBPs), were monitored along the treatment trains of three municipal systems. This monitoring was used to understand the effectiveness of the processes at the different treatment stages, as well as seasonal variations giving rise to high aluminum residual levels. Solutions were explored to maintain residual aluminum at minimum levels for all seasons. Includes 15 references, tables, figures.
