Aerobic composting has been one of the fastest ways to fertilize soil products via organic decomposition under an oxygen-rich environment. Among them, the aerobic composting reactor can be one of the most important facilities during aerobic composting in recent years. However, some challenges are still remained in the aerobic composting reactor, including the long duration, low maturity
Jan 14, 2021 · The composting experiments were performed for 32 days in 5 L reactors. The results showed that carbon sources could change the nitrogen conversion and improve the compost quality.
Feb 1, 2015 · Gaseous emissions and the biological turnover of organic household wastes were studied under controlled conditions in a compost reactor (55°C, moisture content 65% w/w, O2concentration 16% in
Aug 13, 2022 · This study describes a design and construction of a smart composting reactor for improved composting process control and compares the developed system with other laboratory-scale reactors and commercial devices available for this purpose.

Apr 1, 2024 · In this study, the combined application of reactor and static composting (RSC) was used to produce organic fertilizer of CM (OCM), and heavy metals, ARGs and bacterial community structure was investigated.
Composting is an important way to recycle manure into soil as an organic fertilizer or conditioner. However, approximately 50% of the total nitrogen in manure is lost in the form of ammonia during composting, and this loss has an environmental impact on human health. Therefore, to reduce ammonia emission during the composting process to improve the quality of organic fertilizer and reduce its
Feb 28, 2024 · Currently, the water ecological environment is severely polluted and traditional bioreactors have issues with high energy consumption and greenhouse gas emissions. However, a promising solution is the bacterial–algal reactor, which is a green bioreactor that can simultaneously treat sewage and fix CO2. The main configurations of bacterial–algal reactors, including several types, activated
Oct 10, 2020 · Composting technology is widely used and different technologies have been applied from static heap to windrow composting, and to intelligent reactor composting since the rapid development of landless intensive livestock farms and improved awareness of environmental impacts.
Feb 1, 2024 · The von Kármán box (1) is illuminated by a LED tube light fixture (2) and diffuser (3) so that high-speed video can be used to capture droplet breakage events. Two syringe pumps, (4) and (5), are connected to a T-junction fitting (6). A reservoir supplies deionized water to one of the syringe pumps (4).
Dec 1, 2016 · Thermal resistance of the reactor can be written as: (25) R R = 1 k R = R c + R l + R s where R R is the total thermal resistance of composting reactor illustrated in Fig. 1 (W −1 m 2 K); k R is the heat transfer coefficient of the composting reactor (W m −2 K −1); R c, R l and R s are thermal resistances of surface A 1, structural and
Jun 1, 2021 · Therefore, lignin-cellulose based biomass was composted in unaerated cylindrical compost reactors size 20 to 70 m3 for 140 days. The biomass comes with C:N ratio of about 25:1, water content of 43
A 200 L compost reactor was constructed in which temperature, humidity, oxygen concentration and airflow rate through the composting matrix could be controlled. Fourier Transform Infrared (FTIR) spectrometry was used to characterize the gaseous emissions from the composting vessel under different operation conditions.
Sep 6, 2017 · The use of composting that can transform this OSW into stable and mature organic matter in the shortest period possible is the most suitable way of managing such residue. This chapter presents the possibility of treating OSW through composting in facultative reactors. 2.
Compost is essentially the decaying of organic matter. Primarily, a mesophilic phase occurs, followed by a thermophilic phase. For centuries man has been utilizing the latter process to increase soil fertility, reduce organic ordure volumes and treat contaminated soils.
