2023/11/10/ · Composting is a biochemical as well as a heterogeneous process, and the turning operation is important to maintain aerobic conditions and improve the efficiency of the composting process. Therefore, the turning frequency is an important factor for the precise control of the composting reactor. It is necessary to determine the changes in

The second experiment would be d one by temperature controlled around 35o C and the result is maximu m content 55.07% v/v and production rate 1.031 l-H2/ l/day or 106 mmo l H2/l/day. Further studies using an anaerobic reactor with the addition of temperature control, pH, and substrate particle size and the expected product gas produced with a

2022/11/1/ · We previously confirmed that the use of temperature-controlled laboratory-scale reactor system with 12 g mini-reactor could simulate an autothermal larger scale composting (Nakasaki et al., 2005). The temperature of the mini-reactors were controlled in an incubator as following temperature program: temperature began from

3. A composting reactor venting system, the overall venting system comprising: the ventilation device adopts a mode that a flowmeter is connected with a controller, the ventilation size is controlled according to the actual gas flow rate, the temperature control device is formed by integrating a temperature measuring probe and a heating device,

The reactors were 4-l glass cylinders with seals encapsulated with fluorinated ethylene propylene Teflon. To compensate heat losses during compost self-heating due to the high surface-area to volume ratio of the reactor (Petiot and de Guardia, 2004), the wall temperature of each reactor was controlled. Thus, each reactor had an external jacket

2007/3/27/ · The main objectives of this work were to investigate the evolution of some principal physico-chemical properties (temperature, carbon dioxide, oxygen, ammonia, pH, electrical conductivity, organic matter) and microbial population (mesophilic and thermophilic bacteria and fungi) during composting poultry manure with wheat straw in a reactor

2023/11/1/ · The biotic were described in terms of the compost reactor type, size, structure, functions, and control . The compost reactor with multifunctional coupled automated control had better process regulation and HAs yield, reaching 139–248 g kg −1 on a pilot-scale. The abiotic were described in terms of the reaction

2020/8/5/ · A thermocouple in the center of the reactor was used for temperature control. The temperature-feedback control of blowers was maintained for the control of composting temperature at the set point. The details of laboratory composting reactor system were given by Şevik et al. . The control logic of the composting temperature (T)

2016/12/1/ · Reactor systems make composting process easier to control in terms of temperature, moisture content, gas emission, and compost quality (Haug, 1993, Mason and Milke, 2005, Orthodoxou et al., 2015). They have attracted more attention compared to static pile or windrow systems in recent years, especially in heavily populated areas.

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.
