industrial Urban sludge compost tank-Composting Machine

Therefore, industrial-scale sewage sludge composting was shown to be an effective tool for the elimination of indicator strains of fecal contamination resistant to certain antibiotics in routine use. Thus, it contributed to the reduction of the spread of ARGs in environmental microbiomes, as well as the transfer of the same in the food chain.

Water | Free Full-Text | The Assessment of Sewage Sludge

Jan 24, 2024 · Sewage sludge, a by-product of wastewater treatment, is garnering increasing attention in the pursuit of closed-loop economy practices due to its highly beneficial fertilizing properties. However, like any technique, using sewage sludge as fertilizer has potential and limitations. Heavy metals within sewage sludge are a primary limitation curtailing its application as a fertilizer. This study

Sewage Sludge Management for Environmental Sustainability: An

Jan 1, 2022 · Sewage sludge (SS) is the solid, semi-solid, or liquid residue generated during the treatment of domestic sewage in wastewater treatment plants (WWTPs), whose correct destination is one of the biggest challenges for sanitation services globally (Zhen et al. 2017; Raheem et al. 2018) since the worldwide 7.6 billion people excreta must be disposed of in some way.

Centralized management of sewage sludge and agro-industrial

Jul 1, 2017 · 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 environmental problems and risks for human health (Hendrickx et al., 2009).

Compost Quality and Sanitation on Industrial Scale - MDPI

Aug 17, 2021 · 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 difficult

sludge composting - principle and conditions governing its use

Composting is controlled fermentation that converts organic matter aerobically and produces stable humic and pre-humic compounds (figure 1). Aeration will only be effective if the medium is air-permeable. Dewatered sludge often has a low porosity; a bulking agent has to be added, usually in the form of a carbonaceous support (20% of the mixture

Therefore, industrial-scale sewage sludge composting was shown to be an effective tool for the elimination of indicator strains of fecal contamination resistant to certain antibiotics in routine use. Thus, it contributed to the reduction of the spread of ARGs in environmental microbiomes, as well as the transfer of the same in the food chain.

Application of hyperthermophiles in sludge composting: a

Oct 19, 2023 · Sewage sludge treatment and disposal remains a challenging problem. Composting of sewage sludges is gaining increasing attention due to its cost-effectiveness, operation convenience, advantages in lifecycle management, and low greenhouse gas emissions. Disadvantages, such as long reaction time, significant land area occupation requirement, potential risks of residual heavy metals, and emerging

Combined Aerobic Composting of Municipal Solid Waste and

Collection of sewage sludge was done from the municipal water treatment plant situated in the north-east end of Jalgaon city. Sewage sludge sample was in semi solid form and collected in air tight plastic bins to enclose it from surrounding. A 25 kg segregated vegetable waste was mixed with 5 kg sludge so as to make ratio for composting as 5:1.

Sanitary and environmental aspects of sewage sludge

Apr 19, 2019 · 2. The global production of sewage sludge and the main directions of its management. At the European scale, the 91/271/ECC urban wastewater treatment directive adopted in May 1991 imposed the collection and treatment of wastewater in agglomerations with a population equivalent (PE) of more than 2000.

Sustainable Use of Sewage Sludge in Soil Fertility and Crop

Jan 1, 2022 · Sewage sludge contains a large amount of salts (such as salts of sodium (Na), calcium (Ca), and K) and minerals that increase the EC of the soil. In this regard, Akbarnejad et al. ( 2013) reported that with increasing amounts of municipal solid waste compost and SS from 15 to 30 ton ha −1, OC and EC of soil increased.

Wastewater treatment - Sludge, Disposal, Treatment | Britannica

Wastewater treatment - Sludge, Disposal, Treatment: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is generated from chemical

Advances in sewage sludge application and - ScienceDirect

Sep 1, 2023 · Settled sludge from sludge treatment ponds has also been used to ‘mix’ compost from solid waste, as shown in Accra, Ghana; farmers in Ghana, Mali, and Benin have been known to bribe septic truck drivers to deposit fecal matter in their fields [50]. The most critical aspect is the SS quality, as it will influence the stabilization procedure

Sustainability | Free Full-Text | Sustainable Sewage Sludge

Jun 21, 2019 · Nutrient recovery from secondary resources, such as wastewater, has received increasing attention in recent years. Nutrient cycle sustainability and recycling approaches are important measures under development and considerations. This paper aims to present an overview of routes and technologies for nutrient recovery from sewage sludge and measures for improving their sustainability. First

Co-composting of Municipal Sewage Sludge and Landscaping

Nov 16, 2016 · Compost with nutrient-rich organic matter can be produced from renewable biomass materials such as municipal sewage sludge, landscaping waste and others. In this study, co-composting of municipal sewage sludge and landscaping waste as a soil amendment using 10 m3 pilot scale bioreactor system was tested. The temperature, oxygen level, moisture content and pH were monitored throughout the
