Impact/Purpose:
The WBAs were developed to be freely accessible over the Internet as web pages, providing drinking water practitioners (i.e., operators, regulators, engineers, professors, and students) two learning tools to explore inorganic chloramine chemistry in an interactive manner without requiring proprietary software or user modeling expertise. The WBAs allow the user to specify two side-by-side simulations, providing a direct comparison of impacts associated with changing simulation conditions (i.e., free chlorine, free ammonia, and total organic carbon concentrations; pH; total alkalinity; and temperature). Once completed, the user may download simulation data to use offline. The WBAs’ implementation along with example simulations are described.
Description:
Two web-based applications (WBAs) relevant to drinking water practice are presented to (1) simulate inorganic chloramine formation and stability, including a basic inorganic chloramine demand reaction for organic matter and (2) generate chlorine breakpoint curves. The model underlying both WBAs incorporates a well-established inorganic chloramine formation and decay model.
