Environmental and Economic Performance of Sludge Composting

Sep 20, 2022 · Sewage sludge is a widely generated unavoidable waste, the management of which remains the subject of ongoing research. Sludge can be contaminated with heavy metals and pathogens, which complicate its use, but sewage sludge also accumulates a large amount of essential nutrients, which makes its use highly desirable.

Study of Compost Based on Sewage Sludge and Different - MDPI

Apr 4, 2024 · The characterization of compost compositions on the basis of sewage sludge and structural materials (straw, sawdust, bark) composting is described. A comparison of the most often used for composting and characterization of structural materials is also presented. Sewage sludge and structural materials were mixed in different ratios and composted in piles (laboratory scale) for 3 months

Enhancing Optimal Resource Recovery from Municipal Wastewater

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

Composting of Sewage Sludge with a Simple Aeration - Springer

Feb 2, 2018 · The objective of this study was to examine the feasibility of sewage sludge composting using a simple aeration method. Two consecutive composting trials (run A and run B) using Japanese sludge and woodchips (1:1, v/v) were conducted in cubic boxes (0.45 × 0.45 × 0.45 m3) made by plywood at Okayama University. Air was forced up through small holes perforated on two open-ended parallel PVC

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

Industrial Composting of Sewage Sludge: Study of the

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

Effects of sewage sludge immobilized by composite - Springer

Nov 11, 2023 · Sewage sludge treatment and disposal has become a pressing issue in China. Sewage sludge was passivated by composite phosphorus-bearing materials to decrease heavy metals bioavailability. The optimum immobilizing conditions that were 5 g of phosphate rock, 3 g of calcium superphosphate for 100 g sludge and 14 d of passivation time were determined by an orthogonal test. The physico-chemical

Sludge Composting - an overview | ScienceDirect Topics

2.1 Objectives and scope. To compare the carbon emissions of two sludge composting technologies, this study took 1 ton of excess sludge (80% water content) from a wastewater treatment plant as the research object. The two sludge composting technologies investigated were aerobic composting and vermicomposting.

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

Industrial-Scale Composting of Rice Straw and Sewage Sludge

The amount of sewage sludge generated in Spain is around 1.2 million tons per year (dry matter) [11]. This waste can be used for agriculture and building materials,

Sewage sludge treatment technology under the requirement of

Oct 1, 2022 · Due to the outstanding efficiency in carbon, nitrogen, and phosphorus removal, activated sludge has been the most widely used technology in wastewater treatment industry for over a century. Waste activated sludge (WAS) is a vital by-product of sewage treatment.

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.

Improving sewage sludge compost process and quality - Nature

Jan 14, 2021 · 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 composting

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

Wastewater treatment sludge composting - ScienceDirect

Jan 1, 2023 · Aerobic composting was found to be an effective way to degrade triclosan in sewage sludge, as it effectively degraded and inactivated triclosan during the thermophilic phase, thus ensuring the stability and safety of the composting products.
