PhD Defence Nazanin Moradi
On Monday 28 October 2024, the PhD Defence and Awarding Ceremony of Ms. Nazanin Moradi from Iran, will take place. Her promotors are Professor Damir Brdjanovic & Professor Mark van Loosdrecht.
The title of her thesis is:
Ozone-Based Advanced Oxidation Processes for Removing Contaminants of Emerging Concern from Digestate Supernatant: Application and Modeling
Research Summary:
Organic waste constitutes a significant portion of global waste, prompting the need for sustainable solutions. Anaerobic Digestion (AD) emerges as a vital process, converting organic waste into renewable energy and digestate. The latter, while rich in nutrients, faces restrictions in direct application due to environmental and health concerns. This thesis addresses this challenge through the exploration of ozone-based Advanced Oxidation Processes (AOPs) as a post-AD treatment for liquid digestate. The research highlights the efficacy of ozonation in removing contaminants of emerging concern (CECs) from digestate, overcoming complexities within the digestate matrix. A mathematical model is established to predict ozone consumption, offering fundamental insights into the ozonation process in complex water matrices. Building upon this model, the thesis extends its focus to diverse water matrices, demonstrating the predictive accuracy of CECs removal. Furthermore, the exploration extends to a pilot-scale UVOX Redox® system, a hybrid of UV light and ozone, proving its efficiency, cost-effectiveness, and energy reduction in removing CECs from digestate. The findings of this thesis contribute to sustainable digestate management and offer practical and innovative strategies for digestate treatment, aligned with broader goals of circular bioeconomy practices.
