A Novel Kinetic Ozonation Model for Prediction of Bromate Formation, Bromate Mitigation, and Trace Organic Contaminant Removal

Abstract

Computational Fluid Dynamics has recently gained significant ground in the water industry due to the increased awareness about the tool, process requirements becoming more stringent and maturity of both software and hardware (computational power). Virtual design testing using computational fluid dynamics (CFD) (Nopens et al., 2018), what we like to call ‘virtual piloting' or ‘virtual experimenting', extends testing freedom drastically, does not require real-life system modifications and provides much more system understanding (Rehman et al., 2017; Wicklein et al., 2016). Optimal mixing is important for many wastewater treatments processes. If mixing is accounted for properly, preferably in the design stage, it reduces process footprint, lowers OPEX and increases process reliability and performance. This paper describes two full-scale examples in which advanced 2-phase CFD (liquid/gas) was used to evaluate different design scenarios prior to real-life implementation. The first case relates to the optimal dosing and mixing of coagulant in a primary treatment at a Water Resource Recovery Facility (WRRF) in New Zealand. The second case relates to optimal oxygen transfer and mixing in an industrial WWTP in the Netherlands. CFD was used to optimize a) the influent mixing (avoid short-circuiting) and b) the mixing of the oxygen or coagulant dosed. Based on the simulation outcomes, informed and optimal design decisions were taken.

Designing a Full-scale Ozonation Plant for Maximum Micropollutants Removal and Minimal Bromate Formation, Using Computational Fluid Dynamics Simulation of Chemical Ozonation Kinetics as Optimization and Validation Tool

Abstract

This paper was presented at WEFTEC 2023 in Chicago, IL.

The water authority De Dommel (The Netherlands) is in the process of realizing a full-scale ozone installation (as a result of the AMOZONE virtual piloting presented in the previous event) at the WWTPs of Hapert for demonstration purposes on the removal of MPs. At this stage, the CFD-AMOZONE model is used to achieve optimal and efficient design of the full-scale demonstration facility.

Optimal Micropollutants Removal, Minimal Bromate Formation, and Improved Effluent Quality for the Eindhoven WWTP by Integrating Biological and Ozonation Models

Abstract

Water reuse is clearly becoming a concrete need and the removal of micropollutants (MPs) must be completed while coping with minimal bromate (BrO3) production while coping with effluent limits. The Netherlands will soon implement a national regulation for MPs removal and BrO3 discharge. This generates a rising interest in the application of ozonation at the effluent of WWTPs as one of the most cost-effective solutions to remove MPs, with the main drawback of BrO3 formation. However, if properly operated, ozone can be used while minimizing the BrO3 formation. Mechanistic models provide in-depth understanding of the complex net of reactions occurring in an installation. Waterschap De Dommel made and still makes large use of the Eindhoven WWTP biological model for optimisation, operation, and planning. In this work the Eindhoven WWTP biological model was extended with the AMOZONE model to investigate improved control strategies that could save energy and resources while coping with the effluent legislation
