Abstract Background This review sheds light on the topic of phosphorus (P) recovery from hydrothermal carbonization (HTC) organic waste. The paper focuses rising need for securing alternative P sources increasing demand, in addition to development HTC as a thermochemical technique waste valorization. Results article studies definition P‐recovery HTC, while introducing notion availability, which is significant factor studying efficiency P‐recovery. A brief comparison between different treatment techniques streams presented, and advantages are highlighted among techniques. Furthermore, mechanisms P‐transformation during reactions studied, effect various parameters P‐destination emphasized. Finally, applications products laboratory industrial scales studied assess feasibility application. Conclusion In short, offers detailed insight into definition, mechanism, potential wastes within scopes resource management, valorization, fertilizer production. Even though has been applied scales, several challenges persist towards optimizing this process. concludes that adopting P‐availability criterion necessary optimize conditions Further later‐stage recommended, well. © 2023 Authors.

ABSTRACT Wastewater treatment facilities use enhanced biological phosphorus removal (EBPR) to meet discharge quality limits. However, the EBPR process can experience upsets due a lack of influent carbon or inadequate anaerobic zones. By using sidestream (S2EBPR) process, be generated internally through fermentation processes and higher mass fraction attained in smaller volumes. This study investigates nutrient microbial community trends full-scale S2EBPR demonstration at Calumet Water Reclamation Plant. The aims improve model system by better representing activity glycogen-accumulating organisms (GAO) potential competitors phosphorus-accumulating (PAO), which were found high abundance this study. Modifying hydrolysis, GAO glycogen storage ORP parameters resulted prediction improvements approximately 5% for nitrate nitrite 10–60% phosphorus. also uses shotgun metagenomic sequencing profile denitrification pathways PAO GAO. It shows that denitrifying may contribute nitric oxide reduction greater degree than PAO. improves modeling predictions highlights role combined nitrogen S2EBPR.

Optimizing aeration rates via bio-methane potential test for enhanced biodrying efficiency of refuse-derived fuel-3

International Journal of Renewable Energy Development, Год журнала: 2024, Номер 13(5), С. 941 - 951

Опубликована: Авг. 5, 2024

Aeration forms a critical part of the biodrying refuse-derived fuel-3 (RDF-3) and significantly affects fuel’s energy potential. Understanding organic content (OC) RDF-3 is crucial for determining optimal aeration strategy. In this study, we conducted bio-methane potential (BMP) test to estimate OC by observing conversion matter into methane (CH₄) carbon dioxide (CO₂). The observation BMP was using anaerobic digestion approach where substrate inoculum are important parameters considered success test. Various ratios substrate-to-inoculum (S/I) were explored assess their impact on biogas production, our research involved testing four S/I (0.25, 0.5, 1.0, 1.5) focusing identifying Based stoichiometric calculations, sample’s yield per gram volatile solid indicates RDF-3’s 1.5%. This value played role in establishing appropriate rate (AR) process, which determined be 0.6 m³/kg.day, indicating action effective microbial degradation processes. Ensuring correct AR vital maximizing RDF-3. Implementing optimized rates based waste management practices can improve efficiency. enhances RDF quality, reduces moisture, increases calorific value, minimizes greenhouse gas emissions, leading more sustainable efficient waste-to-energy conversion.

Improving Enhanced Biological Phosphorus Removal with Return Activated Sludge Fermentation and Carbon Addition in a Benchtop Sequencing Batch Reactor Treating Real Wastewater

ACS ES&T Water, Год журнала: 2024, Номер 4(9), С. 4110 - 4119

Enhanced biological phosphorus (P) removal (EBPR) with return activated sludge (RAS) fermentation (S2EBPR) is a recent EBPR innovation suggested to achieve more stable and efficient P removal. However, consensus around these benefits the mechanisms of S2EBPR still developing. To further this understanding, three pilot sequencing batch reactors treating real domestic wastewater were operated as or conventional EBPR, without external carbon addition, anaerobic phase. Findings include following: (1) showed small improvement over EBPR; (2) performed substantially better dose added, while did not, but microbial community stability was increased in both; (3) when stopped, high continued for two solids retention times; (4) measured yield larger benefit than observed; (5) phase not good removal; (6) although trends similar, enriched metabolically flexible polyphosphate accumulating organisms importantly, Candidatus Phosphoribacter. Overall, RAS beneficial performance addition minimally without.
