Improving sewage sludge compost process and quality - Nature

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

Composting | Sludge Processing

Composting. Composting is a type of aerobic digestion in which sewage sludge is combined with bulking agents such as wood chip, straw or green wastes prior to composting to provide a pasteurised product. The process is a largely static system which is aerated by natural diffusion and is therefore low in energy demand.

Basic Information about Biosolids | Blong

Dec 15, 2023 · Basics of Biosolids. Biosolids are a product of the wastewater treatment process. During wastewater treatment the liquids are separated from the solids. Those solids are then treated physically and chemically to produce a semisolid, nutrient-rich product known as biosolids. The terms ‘biosolids’ and ‘sewage sludge’ are often used

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.

Sludge Dryers - Sludge disposal, treatment and drying

Apr 7, 2023 · The paddles ensure that the sludge is evenly distributed and exposed to the hot surfaces of the dryer, maximizing drying efficiency. Paddle dryers can be used for various sludge types, including sewage sludge, industrial sludge, and agricultural sludge. One of the most significant benefits of using a sludge dryer is reduced disposal costs.

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.

Resource recovery and waste-to-energy from wastewater sludge

Jun 15, 2020 · With the rapid rise in global population over the past decades, there has been a corresponding surge in demand for resources such as food and energy. As a consequence, the rate of waste generation and resultant pollution levels have risen drastically. Currently, most organic solid wastes are either land applied or sent to landfills, with the remaining fraction incinerated or anaerobically

Oxygen Monitoring Equipment for Sewage-Sludge Composting and

Nov 18, 2018 · The equipment could monitor oxygen concentration online and in real time to optimize the aeration strategy for the compost depending on the concentration indicated by the oxygen-measuring equipment.

Sludge-to-energy recovery − a review

Aug 17, 2020 · Gasification, pros and cons. 3. Conclusions. A comparison of the two established sludge technologies of anaerobic digestion (AD) and combustion with the two more novel oxygen-deficient thermochemical processes of pyrolysis and gasification for resource recovery from sewage sludge reveal major challenges to implementation of the novel technologies.

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

Frontiers | Industrial Composting of Sewage Sludge: Study of

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.

Sewage sludge composting: quality assessment for agricultural

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

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

Sludge Treatment Technologies and Systems, an Introduction

Mar 26, 2024 · Sewage sludge is the largest by-product of used water treatment. Its production is dependent upon influent characteristics and the processes applied.
