Dec 7, 2022 · As increasing soil organic matter is considered one of the main strategies for reducing desertification in Europe, the production and use of high-quality composts has gained importance during the last decade. It is undisputed that the quantity and quality of humic substances (HS) and their fractions, i.e. fulvic acids (FA) and humic acids (HA) in compost are considered important indicators of
Aug 1, 2010 · The aim of this work is the study of recycling urban primary sludge by in-vessel aerobic composting way. Two series of composting trials were carried out in an automated accelerated bioreactor in mixture with agricultural wastes: sugar beet leaves (C1); straw, sheep manure and sugar beet leaves (C2). Treatments were monitored with regard to
Jan 1, 2022 · This composting method has low investment cost, high degree of automation, better control of temperature and aeration conditions, effective sanitation and less odors, relatively short composting time, small amount of fillers, and small area [26].
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.
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 experiments were
Mar 15, 2024 · The impact of earthworms on bacteria and eukaryotic microbial populations, in urban sludge compost was studied using high-throughput sequencing. This research holds significant value for understanding the stabilization process of urban sludge compost treated with earthworms. 2. Materials and methods2.1. Experimental materials

Jan 1, 2019 · Properly maintained methane digestion should ensure obtaining biochemically stabilized sewage sludge and the production of high-caloric biogas. Increasing the degree of sewage sludge digestion and biogas production can be obtained due to the use of various methods, but codigestion is the most effective (Grosser, 2017, Grosser, 2018). The
Jun 20, 2012 · Purpose Urbanization and industrialization in China has resulted in a dramatic increase in the volume of wastewater and sewage sludge produced from wastewater treatment plants. Problems associated with sewage sludge have attracted increasing attention from the public and urban planners. How to manage sludge in an economically and environmentally acceptable manner is one of the critical issues
Livestock and husbandry manure compost tank Organic waste such as poultry manure and animal carcasses such as chicken, pig, cow and sheep manure can be processed and turned into usable organic fertilizer
Apr 1, 2022 · Composting is widely applied as an easy-to-use and economical way to manage organic waste [2], and organic fertilizer is prepared from livestock manure using composting technology. Modern mechanical manure composting is operated using a compact sealed tank with a high degree of automation plot ratio and production efficiency.
Aug 5, 2020 · The adoption of sewage sludge as an agricultural management strategy to improve soil properties and crop production is attracting great interest. Despite many positive effects on soil inorganic and organic components reported for different soil types, little information is available on sewage sludge application on Mediterranean soils, as well as on its use at different dose rates. The
Mar 1, 2019 · Land application after composting is an important method for sewage sludge treatment and improving the low organic matter content of multiple agricultural soils (Ravindran et al., 2021).
It can process river sludge, sewage sludge, etc., and turn it into organic fertilizer through fermentation. The processing capacity of the sludge fermentation tank ranges from 7 to 10 cubic meters per day (the water content is 50 to 70%). We can customize implementable solutions according to your needs.
