Energy-efficient wastewater treatment plants (WWTPs) utilize systems like high-rate activated sludge (A-stage) system to redirect organics from wastewater are redirected into energy-rich sludge (A-sludge). Anaerobic membrane bioreactors (AnMBRs) offer lower footprint and higher effluent quality compared to conventional digesters. In this study, the biological treatment and the filtration performances of AnMBRs for A-sludge digestion under mesophilic and thermophilic conditions were comparatively evaluated through lab-scale experiments, mass balancing and dynamic modeling.

The model was formulated with inspiration from Activated Sludge Models No. 1 and 3 (ASM1 and ASM3) to incorporate essential mechanisms, such as adsorption and storage substrate, specific to HRAS systems.

- Coagulants from water treatment plants typically produce sludge that is often sent to landfills, but utilizing this sludge is encouraged for sustainability.
- This study explores using WTP sludge, specifically iron sludge, as a substitute for conventional coagulants in a high-rate activated sludge system, finding it enhances treatment efficiency.
- The addition of iron sludge improved particulate chemical oxygen demand removal and sludge settleability, while also reducing overall operational costs by 11%, indicating potential benefits for both water treatment facilities and environmental sustainability.
Article Synopsis
- The study highlights the growing importance of small specialty crop farms (SSCF) in the U.S. due to increased consumer interest in local produce.
- Researchers analyzed genomic diversity from bacteria isolated from dairy manure across 10 SSCFs in Northeast Ohio, identifying various sequence types and gene patterns indicating potential transmission between farms.
- Findings revealed that certain isolates carried genes that enhanced resistance to environmental stresses and antimicrobials, suggesting a complex interplay between bacteria and farm management practices over time.
