2015/5/1/ · In this paper, the treatment of composting leachate biochemical effluent (CLBE) by electrochemical oxidation (EO) with Ti/RuO 2-IrO 2 as the anode could achieve concomitantly organic carbon removal (COD) and nitrogen removal (NH 3-N), taking advantage of CLBE inherent high chlorine content.Under the optimal conditions of the

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

2013/6/1/ · 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 were collected daily and chemical analyses and PCR-DGGE were carried out for investigating the influence of composting temperature

2021/7/23/ · This study evaluates the common process and set-up design of a static compost bioreactor for heat recovery. A technology, which fits the goal of a sustainable, growing bioeconomy which combines the utilization of compost heat and compost material. Interest on this technology has been growing the last years but precise data of pilot scale

2017/4/26/ · The IAEA is playing an important role in supporting the sustainable and safe operation of research reactors, and should continue to assist countries embarking on new research reactor projects and facilitating access to facilities for countries that do not have research reactors themselves, a group of experts concluded at a recent Technical

1990/7/1/ · Thermally safe operation of a semibatch reactor (SBR) implies that conditions leading to large accumulation of unconverted reactants are avoided. The various thermal responses of a cooled SBR, in which an exothermic liquid-liquid reaction takes place, can be precisely defined and represented in a diagram with the kinetics, cooling

2022/12/1/ · In this article, we propose a general framework for safe-economic design and operation of semi-batch reactors via integrating advanced process optimization and runaway criteria. The polymerization reaction features a high exotherm, which is the type of reaction where most runaway situations occur [30].

Runaway and thermally safe operation of a nitric acid oxidation in a semi-batch reactor. van Woezik. Engineering, Chemistry. 2000. A number of serious accidents has occurred due to a runaway reaction of a heterogeneous liquid-liquid reaction whereby a secondary side reaction was triggered. A basic lack of proper knowledge of all.

2023/8/14/ · Operational safety of research reactors. The organization operating a research reactor is responsible for its safe operation. An independent regulatory body provides oversight through inspection and enforcement. The IAEA publishes safety standards to support these bodies, offers review services and organizes training. The

2020/5/10/ · Up-flow anaerobic sludge blanket (UASB) reactor belongs to high-rate systems, able to perform anaerobic reaction at reduced hydraulic retention time, if compared to traditional digesters. In this review, the most recent advances in UASB reactor applications are critically summarized and discussed, with outline on the most critical

2021/6/1/ · Therefore, lignin-cellulose based biomass was composted in unaerated cylindrical compost reactors size 20 to 70 m3 for 140 days. The biomass comes with C:N ratio of about 25:1, water content of 43

2020/5/1/ · 1. Introduction. Composting is widely used for converting organic solid wastes into a stable and safe compost that can be reused in agriculture (Meng et al., 2018).The aerobic composting process involves physical, chemical, and biochemical reactions, which are affected by factors such as temperature, particle size, and moisture

2019/7/14/ · The CSO project structure is based on the outline given in the IAEA draft Safety Guide SSG-48. The ageing management for the HFR is evaluated based on the IAEA Specific Safety Guide SSG-10.

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 …
