Amidst growing challenges such as urban densification, climate change, aging infrastructure, and pandemics, engineers must develop an equitable, environmentally sustainable, and resilient urban water cycle. I will highlight results from modeling and lab scale systems showing how biofilms present an opportunity for achieving these advances. I will present a study where biofilm technologies can help reduce energy requirements, chemical addition, and greenhouse gases related to treatment. I will also show how biofilm treatment processes may provide the potential for enhanced process resiliency.
Lastly, I will discuss our ongoing work where we are trying to control who grows in a biofilm or prevent biofilm formation. By integrating modeling and experimental approaches across multiple scales, I uncover unique insights into microbial processes in our urban water system.
