Project Description

This project investigated 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) were 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 were investigated. Overall this project aimed to better understand the constraints on the stability of high concentrated monochloramine solutions.

Honours Thesis completed by Charlotte Andringa-Bate in November 2010.
