The role of grey water footprint in urban wastewater management: from pollution to reuse.

The grey water footprint (WF), defined as the volume of freshwater required to dilute pollutants below ambient water quality standards, has gained increasing relevance as a qualitative indicator of wastewater impact on receiving water bodies (RWB). This study evaluates the WF using real data from a municipal wastewater treatment plant (WWTP) and its associated RWB over an eight-year period (2016-2023). A wide range of pollutants were considered, including organic compounds, solids, nutrients, and heavy metals.

Extracellular polymeric substances (EPS) in sewage sludge management: A call for methodological standardization.

Extracellular polymeric substances (EPS) are crucial in sewage sludge management, influencing key processes such as sedimentation, dewatering, and drying. Despite their importance, the lack of standardized methods for EPS extraction and analysis has led to inconsistent research findings, hindering a thorough understanding of EPS's role in sludge treatment. This review paper addresses this issue by critically comparing various EPS extraction and analysis methods, emphasizing the urgent need for standardization in the field.

Integrating renewable energy in sewage sludge treatment through greenhouse solar drying: A review.

Sewage sludge is the main by-product of wastewater treatment plants, requiring significant environmental and economic burdens for its management and disposal. Recently, solar drying processes, often performed through solar greenhouses, received interest due to their limited energy requirement and renewable energy exploitation. The dried sludge shows significant volume and mass reductions, reducing transportation and disposal costs.

Tackling climate change through wastewater reuse in agriculture: A prioritization methodology.

Water shortages, exacerbated by climate change, are posing a major global challenge, particularly impacting the agricultural sector. A growing interest is raised towards reclaimed wastewater (RWW) as an alternative irrigation source, capable of exploiting also the nutrient content through the fertigation practice. However, a prioritization methodology for selecting the most appropriate wastewater treatment plants (WWTPs) for implementing direct RWW reuse is currently missing.

Wastewater fertigation in agriculture: Issues and opportunities for improved water management and circular economy.

Water shortages are an issue of growing worldwide concern. Irrigated agriculture accounts for about 70% of total freshwater withdrawals globally, therefore alternatives to use of conventional sources need to be investigated. This paper critically reviews the application of treated wastewater for agricultural fertigation (i.

Real-Life Analysis with Erenumab: First Target Therapy in the Episodic and Chronic Migraine's Prophylaxis.

to research retrospectively the efficacy of Erenumab's treatment, thus allowing to describe a summary more in line with the reality observed every day in clinical practice, relative to a sample of patients widely heterogeneous. The study aims to confirm the efficacy of Erenumab, in terms of reduction of migraine days per month, from baseline to month 12 of treatment. Additional objectives included a reduction in the number of days of symptomatic drug use and change from baseline in the Migraine Disability Assessment Score Questionnaire (MIDAS); Methods: the analysis included all patients treated for 12 months with Erenumab during the year 2019-2020.

Respirometry tests in wastewater treatment: Why and how? A critical review.

Respirometry tests are a widely employed method in wastewater treatment field to characterize wastewater streams, assess toxic/inhibitory effects to the biomass, calibrate mathematical models. Respirometry can allow to fractionize the chemical oxygen demand (COD) in biodegradable and inert fractions, but also provide information related to biomass kinetics and stoichiometry through standardized laboratory techniques. Considering the increasing number of emerging contaminants detected in wastewater effluents, such as pharmaceuticals, personal care products and pesticides, respirometry can be a useful tool to promptly assess any toxic or inhibitory effect in wastewater treatment plants (WWTPs) operations.
