Swine wastewater treatment systems achieve 91.7% ARGs removal, with anaerobic digestion responsible for 70.9% of total removal in a full-scale system.
- Why it matters: Understanding ARGs fate and drivers in wastewater treatment is crucial to reduce environmental and public health risks posed by resistant bacteria and genes.
- What they did: The study monitored process-wide units in a system serving 20,000 pigs, analyzing ARGs removal, restructuring, and mechanisms, including variance partitioning and source tracking.
- The result: Anaerobic digestion and sludge significantly reduce ARGs, but aerobic units can cause ARGs rebound and enrichment of high-risk genes, informing targeted risk mitigation strategies.
