Per- and polyfluoroalkyl substances (PFAS) have gained increasing attention due to the potential health risks that they present. Secondary sludge biosolids are known as notable PFAS emission routes environment. In this study, partitioning behavior of 14 were investigated across four secondary wastewater treatment types (activated sludge, trickling filter, biological nutrient removal, rotating c...

Biological processes, such as activated sludge and granular sludge are widely used to remove organic pollutants as well as inorganic pollutants, such as metallic elements1–3, which are known to be potentially toxic, and impact the performance of biological waste treatment processes4. Granular sludge is a dense aggregate of microorganisms, minerals, and microbial produced compounds such as extra...

Renewable energy will play a key role in the future in limitation of greenhouse gas emissions, with particular focus on carbon dioxide. Biomass and waste are considered among the dominant renewable energy sources. Due to their availability on the energy resources market, it has potential to ensure permanent energy generation.1–3 According to the International Energy Agency (IEA), fossil fuels a...

in the present investigation, for the first time in iran, dewatered sludge waste from air heater washing wastewater treatment of a thermal power plant was subjected to investigation of the cement base stabilization and solidification experiments in order to reduce the mobility of heavy and other hazardous metals as well as increasing the compressive strength of the solidified product for possib...

Stabilization/Solidification technologies reduce the mobility of hazardous and radioactive contaminants in the environment through both physical and chemical processes. Four stabilization/solidification (S/S) processes were used to solidify three sample matrices contaminated with arsenic, chromium (VI), lead, cesium and strontium. These sample matrices were Idaho National Engineering and Enviro...

From the perspective of a circular economy that prioritizes resource reuse and recovery, sewage sludge could be source nutrients for agricultural soils or energy, depending on its characteristics. Lombardy is region with highest quantity production management in Italy. A methodology was developed to: extract analyze quantitative data (EWC 190805) (2017–2018); collect qualitative from publicly a...

The stabilization of swine wastewaters from swine confined housing by the combination of a upflow anaerobic sludge blanket (UASB) reactor and waste stabilization ponds is a viable alternative to minimize the environmental impact caused by inadequate disposal of swine wastewaters. In the present study, the polluting load of pre-decanted swine wastewater treated with a series of two 0.705 m(3) UA...

The recycling and recovery of organic matter nutrients from sewage sludge for application in agricultural soils is gaining interest, while the presence pharmaceutically active compounds (PhACs) this matrix may have a great impact on environment human health. aim review paper to outline recent research occurrence PhACs their metabolites treatment lines. A total 32 classes therapeutic groups incl...

Anaerobic digestion is the most widely used technology to produce biogas such as methane and hydrogen from the decomposition of organic compounds. The effectiveness of the process depends on the stability of the consecutive reactions i.e. hydrolysis, acidification, acetogenesis, and methanogenesis. The process is widely used in sludge treatment for stabilization and production of methane gas. D...
