However, there is limited research on the heavy metals and antibiotic resistance genes (ARGs) during compost CM. 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.
2024/4/1/ · Accelerated entry of the compost reactor into the thermophilic phase indicates that thermophilic microorganisms are more active and help to maintain higher temperatures (Wang et al., 2018). Static composting began on day 9 and was maintained at a temperature range of 55–65 °C for 8 days (Fig. 2a). The sustained high temperatures
2009/1/1/ · Composting is an efficient and cost-effective process for organic waste treatment. In order to expand our knowledge regarding microorganisms in the composting reactor, bacterial community structures in a variety of composting processes were examined by 16S rRNA gene (rDNA) clone analysis including denaturing gradient gel
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
2021/10/1/ · 1. I set out to iterate and improve the traditional Johnson-Su Bioreactor design to make it easier to make compost. In this video, I show the new composter design and go over the reasons why I tried to improve the Johnson-Su bioreactor. The new composter doesn’t use any plastic and should last a very long time.
Modelling for reactor-style aerobic composting based on coupling theory of mass-heat-momentum transport and Contois equation. Xueqin He Lujia Han Jinyi Ge G. Huang. Engineering, Environmental Science. Bioresource technology. 2018. 31. Semantic Scholar extracted view of "Design and test on an experimental aerobic composting reactor
This study developed a pulse alternating ventilation composting reactor and investigated the effects of alternating ventilation on composting efficiency compared with upward ventilation and downward ventilation. The results demonstrated that alternating ventilation stabilized the moisture content at approximately 60 % while reducing the
Compost Reactor/Compost Heat Exchanger Assembly [19] when composting with an aerated system with one International Journal of Energy Engineering 2020, 10(1): 10-15 13 direction of airflow but higher than 0.63 days reported by by B2 (Figure 5) and the Water Tank (COHEIN) temperature [17]. Similarly, [5] reported compost reactor temperatures
2021/2/18/ · I set out to iterate and improve the traditional Johnson-Su Bioreactor design to make it easier to make compost. In this video, I show the new composter des
XACT. - Containerized Bio. Reactor Composting System. This complete composting system is built into a 40’ (12m) customized container. It has a clean quiet and pristine appearance making it ideally suited for city settings such as hospitals, universities, shopping malls. The system includes the Model 510 BioReactor, Vertical Mixer, Conveyors
2016/7/6/ · In this research, a pilot silo composting reactor and chicken manure with 70% moisture content were used as raw materials for a composting trial. The focus of the study was on the effect of different ventilation rates on composting. Three different ventilation rates (12, 6, and 2.4) m3·min-1 were used to pass air into the compost. The
2010/6/1/ · Batch experiments were conducted for feces composting using an aerobic composting reactor with sawdust as bulky matrix. In the 14-day composting processes at 35±2 and 55±2°C, compost samples
A static aerated Compost Reactor (CR) was developed in Kitele, Kenya, and used for evaluating the efficacy of generating, extraction, and utilization of compost heat as a
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
