2018/1/31/ · The composting of cattle manure was conducted using an 18.8 L reactor with three different amounts of total air supplied (1080, 3240 and 10,800 L/kg dry mass) during 360 h of composting using
2018/1/1/ · The smuggled cigarette tobacco can be treated through composting in facultative reactor. • Results showed its efficiency in toxicity free and stable compost. • The composting remained at optimal ratio without the need for manipulation. • Composting facultative reactor it is an efficient and low-cost technology.
The composting of cattle manure was conducted using an 18.8L reactor with three different amounts of total air supplied (1080, 3240 and 10,800L/kg dry mass) during 360h of composting using
2016/4/1/ · Composting degradation is a complex and interactive process (Seki, 2000, Woodford, 2009), but only limited variables can be considered in modeling and simulation.Thus, despite various models describing substrate degradation, there is no standard mathematical model for composting process (Kaiser, 1996, Mason, 2006).One
2024/2/1/ · Reactor composting is the process of aerobic fermentation of organic waste, such as food waste, livestock manure, and crop straw, in an integrated closed reactor. By investigating the effects of temperature and composting time on various physicochemical indicators of compost, the optimal temperature condition was
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.
2012/12/15/ · The right combination of having optimal process variables combined with an appropriate reactor design allowed the thermophilic stage of the composting process to be speeded up, hence obtaining a compost product, after just two weeks of processing that (with the exception of the moisture content) complied with the Spanish legal requirements
2020/10/10/ · The composting reactor is a closed structure, so it is less affected by external temperature. Static heap and WC are open composting systems, which are vulnerable to external temperature changes, especially in winter when the ambient temperature is low and it is difficult to raise the temperature of materials. In addition, the
Key takeaway: 'Optimal composting conditions for cattle manure include 0.45 L/min kg dm aeration rate, on/off sequencing aeration, and full turning, with weight losses and heat generated significantly influenced by total air supplied.'
Data obtained from the trials shown that the compost in the prototype reactor got a temperature of 60 °C, compared with the temperature of 55 °C reached by the 70 reference pile. This temperature was 60 50 not maintain for long time, because as 40 soon as the temperature reached 50 °C 30 the rotation process was performed to 20 oxygenate the
2023/11/10/ · In order to maintain the composting reactor in an aerobic state during the composting process, the composting kinetics model can be used to predict the temperature of the composting reactor. When the predicted temperature is lower than the actual temperature. Processes 2023, 11, x FOR PEER REVIEW. 6 of 14.
2024/2/1/ · This study set three experimental groups with varying ventilation intensities based on self-made alternating ventilation composting reactor (AL2: 0.2 L kg −1 DM·min −1; AL4: 0.4 L kg −1 DM·min −1; AL6: 0.6 L kg −1 DM·min −1) to explore the optimal alternating ventilation rate. The results showed that the cumulative ammonia
2022/8/13/ · 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.
