A deeper look at the role of oxygen on bio-kinetics in wastewater reuse systems

Wastewater reuse by biological tertiary treatment of secondary effluent is gaining interest as a promising sustainable solution in water-scarce environments worldwide. Media attached systems, as high rate biofiltration and Soil Aquifer Treatment (SAT), are well-practiced processes, especially in Israel, for producing high quality reusable water to support food production. During the flow of the secondary effluent through the media, the attached microbiota utilizes and removes residual organics and nitrogen by various metabolic pathways and rates determined by environmental conditions. Oxygen availability is a key parameter for system design and optimized performance. However, microbiota structure-function (bio-kinetics) links in such engineered systems have not been elucidated similarly to other engineered processes for biological wastewater treatment. In this seminar, two case studies will be presented: (1) the role of oxygen in the tertiary treatment: a pilot biofiltration research conducted at the SHAFDAN Wastewater treatment plant and (2) lab scale research simulated SAT conducted at Columbia University, NY, focusing on new methodologies using next generation sequencing, the associated substrate transformation and modeling.
