2021/9/1/ · Composting operation and physiological characterization. Chicken manure and rice husks were obtained from the farm in Harbin, China. Composting reactor referred to previous research (Xie et al., 2017). The reactor volume was 57.6 L, and 6.0 kg dry chicken wastes and 0.6 kg dry rice husk were mixed completely in each reactor.

2008/1/30/ · The contents of fed-batch composting (FBC) reactors often aggregate after prolonged operation. This process leads to irreversible breakdown of the decomposition reaction and possible alteration of the bacterial communities. We compared the structures of bacterial communities in reactors under aggregate and optimal

2019/12/1/ · During 200 days of continuous operation, the reactor start-up was achieved within 30 days; a high total nitrogen removal efficiency of 80% was achieved and stably maintained under an aeration rate

a delay of compost process of these reactors till pump operation pause after day 62 (Fig. 6). During the first day of operation, the pipe loop heat exchangers were rinsed with water solely to

These composting plants adopt continuous operation systems that input daily fresh feed and continuously aerate and intermittently mix it. There are many research articles on composting

A daily feeding ratio of 10% ensured stable performance of TSC using an integrated automatic reactor; the efficiencies of organic matter degradation and seed germination index (GI) reached 80.88% and 78.51%, respectively. SS for seven days further promoted the quality of the compost by improving the GI to 91.58%.

The BUSS-Loop® Reactor has been adapted to continuous system and is being used increasingly due to its great potential to intensify the reaction. Significant shorter reaction time and the reduction of by-product formation is often achieved. Such advantages in productivity and quality, accompanied most of the times by the reduction of

mode exclusively to treat compost leachate pretreated in AMBR reactors [11,38,39]. In effect, to the best of our knowledge, the anaerobic digestion process of raw compost leachate in semi-continuous

2009/4/6/ · The reactor was equipped for continuous monitoring of gas flow and emissions of CO 2 as well as for measurements of NH 3, N 2 O and CH 4 contents in the compost CA, USA) according to the manufacturer’s protocol with the following modifications : 5 g of the frozen compost samples was mortled in liquid nitrogen for 5

2022/2/14/ · The highest pH was recorded on day 17 with 7.79 in the continuous reactor, while it was 7.85 on days 22 to 24 in the batch ones. The reported data for the batch reactors are the average results of the batch reactors, which is done at least three reactors. Figure 3 shows the methane content of the biogas produced in the batch and

2015/10/24/ · In literature, a continuous reactor operation can be studied from 14 to 700 days, and the decrease of hydrogen producers can be attributed to the development of homoacetogenic microorganisms during the reactor’s operation (Lin et al. 2006; Kim et al. 2006; Fang et al. 2002; Zhao et al. 2008; Lay et al. 2012; Kim et al. 2010; Ren et al. 2010).

2024/6/1/ · The optimal HRT reflects the performance of the reactor in continuous operation. A shorter optimal HRT can improve the hydrogen production rate and considerably reduce the bioreactor size and capital cost. Substrate, reactor structure, bacterial species, fermentation environment, and other factors have obvious effects on

Optimizing a batch requires precise recipe control, the right measurement and batch analytics. It starts with precise material addition measurement compositional analysis and control. Emerson’s field devices and control systems help you avoid errors that cause reduced reaction rates, off-spec product, and costly reprocessing.

2023/1/1/ · The innovation prospects of the composting device include the internal configuration of the composting reactor design and combine with the intelligent control
