Many authors have studied the composting process on different sewage sludge scales with distinct materials [18–21], and the composting process of rice straw with other waste types [22–24].
Feb 18, 2016 · The main objectives of this study were to investigate the compostability of wastewater treatment sludge (WTS) containing different bulking agents (BAs) and to determine the most efficient BA. Four different compost trials consisting of mixtures of wheat straw (WS), plane leaf (PL), corncob (CC) and sunflower stalk (SS) with WTS were performed

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
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.
The former has stable composition, low C/N content and high-water content. Because the sewers often flow into industrial wastewater, they contain heavy metals and other harmful substances. The nature of industrial sludge varies greatly from industry to industry. Farm manure plant sludge can be used as an ideal compost material.
. Sewage Sludge Treatment. HUBER Solutions for Septic Sludge Treatment. Where wastewater treatment is decentralized, septic sludge is produced, and must be evacuated, collected and treated in a centralized plant.
Microbiol., 23 December 2021. Sec. Microbiotechnology. Volume 12 - 2021 | https://doi.org/10.3389/fmicb.2021.784071. Industrial Composting of Sewage Sludge: Study of the Bacteriome, Sanitation, and Antibiotic-Resistant Strains.
Jan 14, 2021 · 3771 Accesses. 28 Citations. Metrics. In present study, the effects of carbon sources on compost process and quality were evaluated in the lab-scale sewage sludge (SS) composting. The
May 8, 2020 · Sewage sludge can be combined with other waste materials such as wood chip, straw or green wastes prior to composting to provide a pasteurised product. Around 20−30% of the volatile solids can be converted to carbon dioxide through composting.
In this work, the evolution of polyphenolic compounds was studied during co-composting of olive mill wastewater sludge and poultry manure, based on qualitative (G-50 sephadex) and quantitative (Folin-Ciocalteu), as well as high pressure liquid chromatography analyses.
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
Nov 30, 2023 · The world is faced with a growing population, increasing pollution, and diminishing resources. As such, there is a growing need to explore the possibility of harnessing resources such as energy from unconventional sources to promote sustainability. Wastewater sludge is a critical point to recover energy in the form of both gas and electricity using either thermochemical, biochemical, or
Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and
