AbstractWater treatment and disinfection of water is necessary for ensuring the health and safety of the end user. As the availability of high-quality water sources become scarce, advancements to improve the efficiency of water treatment practices are needed. Chemical disinfectants (e.g., free chlorine) are commonly used to control bacterial growth in a variety of water systems. However, the high reactivity of these compounds with organic and inorganic material in water systems leads to rapid consumption of the disinfectant. These reactions may make it difficult to maintain an adequate disinfection residual in some water systems. Rising concerns as to the formation of disinfection by-products in these side reactions through conventional means has initiated a shift to the investigation of alternative disinfection practices (e.g., chloramination). However, the effectiveness of novel methods requires validation for the removal of different organisms, and in different water systems.Combining conventional treatment methods with novel water treatment practices provides a clear path to alleviating some of these concerns. Novel technologies that can be used to address these challenges by improving the efficiency of conventional chlorination practices, aiding in the removal of biological contaminants, or by limiting unintended disinfection by-products should be explored. Augmentation of existing practices by magnetic water treatment is promising due to a magnetic field’s influence on charged particles that are common in water treatment and biological systems. Thus, this work aims to determine the effectiveness of these techniques to improve the efficiency of existing chlorination practices for pathogen control in water systems.
