Integrated chloride and chlorine sensor
This research is directed at the development of an integrated chloride sensor for application in municipal water systems. This is an important application as water systems must chlorinate water in order to control disease-causing micro-organisms. Safety requires a sufficiently high residual chlorine concentration throughout the system, concentration at particular locations depends in a complex way on the systems topology, consumption rates, etc. At present suitable sensors do not exist, and an inexpensive, long-lived sensor would make it possible to determine the actual concentrations throughout the system, resulting in improved safety. It will also be possible to use less added chlorine, leading to improved taste and fewer reaction by-products.
