Small Public Water Systems face unique challenges in meeting Stage I & II disinfection byproduct rules. Diffused and spray aeration offer significant advantages in installation and O&M costs for small communities that need to lower THMs in finished drinking water. In this study, bench and pilot aeration assessments were undertaken in order to evaluate the importance and interaction of aeration variables associated with Trihalomethane (THM) and specifically chloroform removal. Bench scale experiments to determine the effect of air stripping on free chlorine levels and water pH were also conducted.
