2001/4/1/ · 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
2002/9/1/ · A compost reactor experiment on household waste was designed to test whether the degradation time could be reduced by actively preventing the temperature from rising until the pH had reached a certain value. The experiments were run with an oxygen level controlled at 16% in the compost gas under two temperature control regimes,
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
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
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.

2016/12/1/ · 1. Introduction. 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
Abstract. In this paper, laboratory- and pilot-scale reactors used for investigation of the composting process are described and their characteristics and application reviewed. Reactor types were categorised by the present authors as fixed-temperature, self-heating, controlled temperature difference and controlled heat flux, depending upon the
2013/7/23/ · Intermittent aeration applied to the five compost mixtures with initial C/N ratios of 12.81, 21.37, 24.66, 29.22, and 37.41 was conducted using fifteen identical cylindrical reactors with volume
2024/2/1/ · To quantitatively assess the potential impact of temperature, oxygen concentration, and moisture content on OM degradation, a mathematical modeling method was employed to investigate the distribution of the first-order kinetic correction coefficient “k” in the compost OM interpretation within the reactor system (Fig. 1).The closer “k” was to
2013/3/21/ · Phillip [121] used three incandescent light bulbs of different power ratings (60W, 100W, 200W) to heat the insulated pilotscale (200L) cylindrical plastic reactor, controlled the temperature and O
The results demonstrated that alternating ventilation stabilized the moisture content at approximately 60 % while reducing the temperature and oxygen concentration range within the reactor. Moreover, it extended the duration of high-temperature (>50 °C) by 31 % and 75 % compared to other two groups.
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)
The composting reactor ensures, to the greatest extent, that the internal temperature of a composting device is not dissipated, thereby improving the composting efficiency; and energy sources are saved. In addition, the composting reactor regulates and controls the composting environment only by controlling the aeration process, and can
4. A composting reactor as claimed in claim 3, characterised in that the drive shaft is of hollow construction and the drive shaft portion is disposed outside the casing and inside the inner casing; the aeration mechanism and the control mechanism are communicated with the accommodating space through the transmission shaft. 5.
