sewage sludge industrial composting machine space saving

2008/10/1/ · In this work, the effect of incorporating an acidic ferrous sulphate waste (SF) over co-composting process of sewage sludge and olive mill solid wastes in a 1:2 v/v wet basis was investigated.

2017/7/1/ · 1. Introduction. Due to the high volume of sewage sludge currently generated worldwide (8.9 million tons of dry solid matter in 2010 according to Eurostat, 2015), as well as its high concentration in heavy metals (especially cadmium), organic micropollutants and pathogens, this waste must be properly managed to prevent

2022/12/7/ · Composting of organic wastes such as sewage sludge, with a view to recovering resources from them, has gained importance in the last decade. In municipal sewage sludge management, the main objective is to maximize the use of nutrients while meeting all sanitary, chemical, and environmental safety requirements, and it can be

2024/3/10/ · Nutrient-rich compost suitable for agricultural purposes and land reclamation can be obtained with aerobic stabilization (composting) of sewage sludge

2011/6/23/ · In further studies Maboeta and Rensburg compared the effectiveness of different bioconversion strategies viz. composting, vermicomposting and a commercial

2023/8/30/ · Sewage sludge composting is a common practice that needs bulking agents due to the high moisture, small particle size and pasty texture of sludge. These

2021/7/15/ · The utilization of nutrients in sewage sludge partly alleviates the economic and environmental constraints, and the composting process has been proved a cost-efficient and simple approach for the recycling of sewage sludge. During the bio-oxidative process, the thermophilic phase is considered to be the most effective stage for the

2024/2/7/ · From waste to resource: New sustainable process transforms sewage sludge into activated carbon. Credit: Journal of Environmental Management (2023). DOI: 10.1016/j.jenvman.2023.119822. Sewage sludge is the solid waste resulting from wastewater treatment. According to data from the Ministry for the Ecological Transition

2023/2/1/ · The objective of this study was to focus only on the treatment of 1 tonne of sewage sludge with a water content of 80%, i.e., the raw materials needed to incinerate the mixture, the energy generated, and the environmental impact were “offset” in co-incineration technology.The system boundary is started from the collection of sewage sludge to

2021/8/17/ · Municipal solid waste and sewage sludge are produced in large quantities that are often managed through industrial composting treatment. Because of their origin, composition, and complexity, ensuring adequate stabilization of the organic matter, and sanitation of fecal contaminants during composting is of the utmost significance, and

The sewage sludge composting pile was performed at industrial scale in the Biosolid Plant of “Biomasa del Guadalquivir”. This pile was located in Vegas del Genil, Granada (37.160791−3.723879) and it was built using a semipermeable film to cover the pile and a ventilator system, as previously described by Robledo-Mahón et al. . The

Composting is widely used for recycling of urban sewage sludge to improve soil properties, which represents a potential pathway of spreading antibiotic resistant bacteria and genes to soils. However, the dynamics of antibiotic resistance genes (ARGs) and the underlying mechanisms during sewage sludge composting were not fully explored. Here, we used …

2020/1/10/ · Smuggled cigarette tobacco (SCT) and industrial sewage sludge (ISS) are important substrates in the process of microbiological degradation, due to the high level of total nitrogen in their composition, which favors the composting process (Zittel et al., 2018b). However, these residues must be combined with structuring agents (sawdust, …

2020/5/1/ · To address this issue, a centre-oriented real-time temperature compensation strategy was designed in this study. Five 9 L reactors (R1-R5) with different insulation strategies were used for the co-composting of dewatered sludge and Phragmites australis and compared. The process performance was assessed by monitoring the temperature, …

2023/2/1/ · GA was applied to optimize the process conditions as a metaheuristic search algorithm. The decision variables of the optimization transaction were the ratio of dewatered sewage sludge and the composting duration. Also, the parameters of pH, temperature, EC, C/N, TOC loss, TN loss, NH 4 +-N/NO 3 –-N ratio, and MC loss were …
