The use of aerobic granular sludge is a promising and future-proof solution for wastewater treatment. implementation this technology requires the development efficient cost-effective methods management excess sludge. aim research was to evaluate effects hydrodynamic cavitation on efficiency digestion. Respirometric measurements were performed at temperature 38 °C an initial organic load 5.0 gVS/L. changes in properties pretreated biomass, kinetics methane fermentation, amount composition biogas produced, energetic evaluation process carried out. A significant influence transfer compounds into dissolved phase demonstrated. degree solubilisation 37% COD 42% TOC.

Air treatment technologies in pig farms. Life cycle assessment of dry and wet scrubbers in Northern Italy and Northeastern Spain

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 922, P. 171197 - 171197

Published: Feb. 24, 2024

Over the years, different solutions were developed and tested to reduce emissions of ammonia particulate matter from livestock facilities. The environmental performances these not always evaluated in detail. This study examines footprint pig production at farm gate, with a focus on housing. Using Life Cycle Assessment, impact transition Spain two finishing farms Italy was considering three scenarios (one baseline them involving an air treatment technology: wet scrubber or dry scrubber). goal quantify scenarios, identify key hotspots, assess reduction efficiency due assessed technologies, analyze trade-offs that come use potential for improvements. Both scrubbers showed reducing housing, affecting categories related pollutants such as matter, acidification eutrophication. However, there between energy resource use. infrastructure consumables required operate added impacts compared baseline. more favorable balance emission trade-offs. In this regard, results similar Spanish Italian farms, although slight variations. Scrubbers had greater effect their along longer periods fattening (closed cycle farms) (transition farm). are environmentally promising, especially where acidification, eutrophication local problems. they alone cannot fully address complex production, which require comprehensive interventions across supply chain.

Synergism of Life Cycle Assessment and Sustainable Development Goals Techniques to Evaluate Downflow Hanging Sponge System Treating Low-Carbon Wastewater

Sustainability, Journal Year: 2024, Volume and Issue: 16(5), P. 2035 - 2035

Published: Feb. 29, 2024

While recent researchers have focused on optimizing the operational conditions of low-carbon wastewater treatment processes, they not sufficiently evaluated sustainability such systems. This study is first to assess performance a facility using an integration techno-economic and life cycle assessment (LCA) criteria accompanied by several indicators. A downflow hanging sponge (DHS) reactor was operated at hydraulic retention time 3.4 h, organic loading rate 3.8 kg COD/m3 sponge/d, 24–35 °C (scenario_1). Another two DHSs were in parallel, i.e., 50% influent bypass (scenario_2) 260 mg/L charcoal addition (scenario_3), providing carbonaceous matter maintain nitrification/denitrification pathway. Employing DHS’s scenario_3 could fulfill most SDGs regarding environmental (e.g., COD nitrogen removals) socio-economic reliability, labor, health safety) targets. The LCA tool also confirmed superior benefits scenario_3, concerning effluent quality, GHG emissions, sludge generation. synergistic interaction approaches ranked proposed DHS modifications as > scenario_1 scenario_2. Hence, current provided innovative strategy that be employed systems worldwide.
