This study indicates that the appropriate elevated starting temperature in the mesophilic phase was able to accelerate the transition into and increase the temperature in the thermophilic phase, leading to rapid decomposition of organic waste.

This thesis explores the roles of physical and mathematical modelling in the prediction of temperature profiles in the composting process. A literature-based evaluation of the performance of laboratory- and pilot scale composting reactors, showed that physical models used in composting research frequently do not properly simulate the full-scale

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

According to this temperature, the harmless process of composting can be completed after 5~6 days. Therefore, in the composting process, the temperature of the compost windrow should be controlled between 50 and 65 °C, but it is better at 55 to 60 °C, and should not exceed 65 °C. When the temperature exceeds 65 °C, the growth of

2015/6/10/ · The calculation based on this model suggests that water can be eliminated most effectively when the aeration is so controlled as to keep the reactor at its optimum reaction temperature i.e., 60°C.

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

2019/3/19/ · The volumes of compost reactors reported in the literature range from 0.4 to 1780 time of 15 min/hr. An airflow meter (Valve Acrylic Flowmeter, Cole-Parmer) and pressure regulators were used to control the airflow rates. The compost temperature was monitored daily (10 a.m., 2 p.m., and 6 p.m.) at three different locations in the substrate ...

2015/9/11/ · Background Composting is one of the sustainable practices to convert sewage sludge into useful agricultural product because it is rich in organic matter, micro- and macronutrients, which is essential for plants growth and soil fauna to live. Therefore, the present study was to recycle the sewage sludge by rotary drum composter. Five sets of

2019/11/1/ · The developed smart composting reactor technology was based on simple and basic parameter control ( Figure 1) combined with the In tank composting principle. loops to optimize conditions, for

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)

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 on organic

2021/6/1/ · PDF | 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 | …

1986/1/1/ · The effect of temperature on the composting reaction of sewage sludge was investigated at 50, 60, and 70 degrees C. The total amount of CO (2) evolved and the final conversion of volatile matter
