Oct 5, 2018 · Composting of sludge or manure is a well-known and used organic matter stabilization technology, which could be effective in reducing the antibiotics levels as well as the antibiotic resistance genes. During sludge or manure composting, the antibiotics removals range between 17–100%.
Aug 17, 2021 · In this study, a comparative analysis is carried out of the compost produced from industrial composting facilities that process municipal solid waste (MSW) and sewage sludge (SS) and compare them with those produced from green waste (VR).
Jun 24, 2022 · Moreover, four bio-enhanced degradation scenarios of FQs were set up according to the different temperatures and carbon–nitrogen ratio (C/N) in the sewage sludge composting stage, and the molecular dynamic (MD) simulation assisted by protein–protein docking was used to screen the external environmental factors that promote the degradation
Aug 25, 2021 · However, the removal of antibiotics and antibiotic resistance genes (ARGs) in the process of co-composting of food waste with sewage sludge has been rarely reported to date. Therefore, we investigated a laboratory-scale composting using food waste and sewage sludge as substrates to study changes in antibiotics and ARGs during composting.
Nov 1, 2019 · It is thus clear that bioleaching conditioning treatment (79.1%) is much more useful than either adding natural zeolite into composting piles or adjusting the C/N ratio of sewage sludge to reduce
Aug 2, 2013 · This study was conducted to investigate the influence of turning on water removal and the interactive influence of turning during different phases. Dewatered sewage sludge was composted using control technology for bio-composting, during which the temperature, free airspace, pile settlement and water reduction were measured and calculated.
Sep 1, 2019 · After 45 days of sewage sludge hyperthermophilic composting treatment, the total MPs abundance was reduced by 43.7 %, while the abundance of MPs <0.3 mm size increased, suggesting that
Dec 4, 2017 · Composting is an efficient way to convert organic waste into fertilizers. However, waste materials often contain large amounts of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) that can reduce the efficacy of antibiotic treatments when transmitted to humans. Because conventional composting often fails to remove these compounds, we evaluated if hyperthermophilic
Jun 24, 2022 · Moreover, four bio-enhanced degradation scenarios of FQs were set up according to the different temperatures and carbon-nitrogen ratio (C/N) in the sewage sludge composting stage, and the molecular dynamic (MD) simulation assisted by protein-protein docking was used to screen the external environmental factors that promote the degradation of
Sep 1, 2023 · Livestock manure is often contaminated with heavy metals (HMs) and HM resistance genes (HMRGs), which pollute the environment. In this study, we aimed to investigate the effects of the aqueous phase (AP) produced by hydrothermal carbonization (HTC) of sewage sludge (SS) alone and the AP produced by co-HTC of rice husk (RH) and SS (RH-SS) on humification, HM bioavailability, and HMRGs during
Mar 4, 2022 · The pertinent challenges associated with effective treatment of fecal sludge in medium scales necessitate alternative means for land application. The of compost preparation from sewage sludge and their modes of application to the agricultural fields have profound impacts on the soil ecology and environment. Besides the chemical conditioning effects on soil organic matter, they also
Sep 5, 2020 · Enhanced removal of antibiotic resistance genes and mobile genetic elements during sewage sludge composting covered with a semi-permeable membrane - ScienceDirect. Journal of Hazardous Materials. Volume 396, 5 September 2020, 122738.
Dec 24, 2021 · Wastewater treatment generates a huge amount of sewage sludge, which is a source of environmental pollution. Among the alternatives for the management of this waste, industrial composting stands out as one of the most relevant. The objective of this study was to analyze the bacterial population link
Apr 1, 2020 · Cui et al. (2020) investigated the effects of the atmospheric environment of composting plants on ARG abundance during sewage sludge composting using smTC and conventional thermophilic composting
Sep 20, 2022 · Composting is one of the ways to return sewage sludge nutrients to the soil and thus keep them in the economic cycle. This well-known technique is still being developed in search of more advanced, optimal solutions. This study presents the results of an environmental and economic analysis of the sludge treatment processes used in a municipal wastewater treatment plant. The sludge (up to 4700
