The project investigates the preparation and stability of concentrated preformed monochloramine solutions, with the potential application of remote area redosing to maintain disinfectant residual. Various conditions (such as pH and temperature) will be investigated for their affect on the formation and stability of high concentrated monochloramine solutions, and the optimum conditions determined. The effect of redosing with concentrated solutions on disinfection by product formation will also be investigated. Overall this project aims to better understand the constraints on the stability of high concentrated monochloramine solutions.
