Simultaneous simulation of pathogen inactivation and bromate formation in full-scale ozone contactors by computer software

This article introduces ozone contactor model (OCM) software developed for full-scale ozone bubble-diffuser contactor design and optimization. OCM software can be used by utilities to optimize reactor design and operation and to demonstrate compliance with regulations regarding pathogen and bromate control in drinking water. The software developed in this study simulates full-scale ozone bubble-diffuser contactor performance for drinking water treatment. The OCM software can be used by engineers for designing ozone disinfection systems, by plant operators for system operation optimization and regulatory compliance demonstration, and by government officials for drinking water regulations development. The OCM software was designed to be user-friendly with graphical user interfaces so users can perform complex simulations under various design and operating scenarios without extensive training. This article also suggests that model simulation is a promising tool for plant design and optimization, possibly beyond the ozone disinfection processes presented.
