Feb 10, 2018 · A detailed description of the WWTP and the composition of the generated mixed sewage sludge is available in the SI of this paper (section SI-1). The total solid (TS) content of the mixed sludge was 3.4% and the volatile solid (VS) content was 75.2% of TS. In this study, the C in sewage sludge was considered biogenic in origin.
Feb 13, 2014 · Sludges, Soils. Abstract. Four commonly used sewage sludge treatment techniques in China are compared, each with and without the combination of anaerobic digestion: composting, co-combustion in power plant, thermal drying-incineration, and cement manufacturing.
Jan 1, 2022 · Sewage sludge management is important for avoiding emissions and mitigating negative effects on the atmosphere, human health, and long-term development. Cities generate hundreds of tons of waste annually, the bulk of which is sewage sludge, as the global population expands, and urbanization occurs.
Apr 6, 2015 · Sludges, Water treatment. Sewage sludge, the most important byproduct of biological wastewater treatment, is considered an important source of secondary pollution in aquatic environments, linked to health problems and even deaths in humans. In 2012, China generated more than 68.5 billion metric tonnes of wastewater, and this is expected to rise
Sewage sludge is the residual, semi-solid material that is produced as a by-product during sewage treatment of industrial or municipal wastewater. The term "septage" also refers to sludge from simple wastewater treatment but is connected to simple on-site sanitation systems, such as septic tanks . When fresh sewage or wastewater enters a
Oct 1, 2022 · Sludge from industrial wastewater treatment plant can be valorised by chemical and biological process. •. The waste produce in resin industries can be seen as a resource for other industries. •. Resin industries can recover energy by sludge anaerobic digestion. •. Industrial wastewater can be treated with wastes.
Jan 14, 2013 · While the EPA has given the use of sewage sludge its blessing some of its own scientists disagree that it’s safe. And for good reason. When you spread sludge on farmland or use a bag of compost you bought at a nursery or home-and-garden supply that’s made with sludge, you’re also spreading contaminants.
May 26, 2014 · The electricity may be produced using the stack gases of sludge incinerator; nonetheless, the high global warming potential (GWP) and oxidation of nutrient compounds are important barriers for
Mar 19, 2021 · Background Human wastewater biosolids, hereafter referred to as biosolids, are produced in significant quantities around the world and often applied to an extensive land mass including agricultural fields, forests, mine lands, and urban areas. Land-application of biosolids has been reported in peer-reviewed and non-peer-reviewed work to change soil organic carbon stocks in varying amounts
Mar 15, 2014 · A cost-combined life-cycle assessment was conducted to estimate the environmental and economic burdens of 13 sewage sludge-treatment scenarios in China. Results showed that anaerobic digestion was a suitable alternative to reduce both environmental and economic burdens because this approach reduced dry mass volume and applied energy recovery.
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).
Oct 27, 2015 · In order to use sewage sludge (SS) composts in agriculture, it is extremely important to estimate the quality of compost products. The aim of this study was to investigate the quality of composted SS as a fertilizer and soil amendment especially in semi-arid areas. To determine the quality and agronomic value of the SS compost products, analyses on pH, electrical conductivity, organic matter
