The composting of organic solid waste, the mixture of fruit and vegetable leftovers enriched with night soil, was investigated in a closed thermally insulated reactor. It was found that 80.9 % of the original substrate biodegraded after 14 days.

The composting of organic solid waste, the mixture of fruit and vegetable leftovers enriched with night soil, was investigated in a closed thermally insulated reactor. It was found that 80.9 % of the original substrate biodegraded after 14 days. A mathematical model of the column reactor was proposed where the biodegradation rate of the organic

2024/5/1/ · Not many compost studies have been conducted in small-scale compost reactors. It is considered that a C/N ratio of 25:1 to 30:1 and a moisture content of 60–65% is optimal for the composting process [43,44]. Several preliminary pilot trials conducted to determine the manure/sawdust combination that adjusted the moisture

2008/6/1/ · Abstract and Figures. The contents of fed-batch composting (FBC) reactors often aggregate after prolonged operation. This process leads to irreversible breakdown of the decomposition reaction and

2024/5/15/ · The diagram shown in Fig. 1 illustrates the design of a bench-scale nutrient recycling system specifically designed for the recovery of NH 3 from thermophilic composting of SAS. The system comprised a 200 L cylindrical composting reactor with a maximum composting capacity of 50 kg wet weight (ww), securely positioned on rotating

composting process is the raw material selection and opti-mal composting conditions. The optimal factors for a bet-ter composting process are carbon-to-nitrogen ratio (C/N),

2023/11/10/ · According to the principles of composting, a kinetic model of composting based on the change in CO2 gas concentration and heat balance in the

A Gram-negative, rod-shaped, spore-forming and moderately thermophilic bacterium, strain KWC4(T), was isolated from a composting reactor. Cells of strain KWC4(T) were 2.0-5.0 microm long and 0.5-0.7 microm in diameter. Strain KWC4(T) grew aerobically at 32-61 degrees C, with optimal growth occurring

2020/7/18/ · The optimal use in reactor composting of heat produced from organic waste is to provide a thermophilic stage for more extended periods as opposed pile composting to degrade substrate in a short time . There is an energy budget of composting reactor with biomass transportation, compost delivery, and energy in

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 conditions. The results

2020/6/28/ · The optimal moisture content (MC) in composting influences oxygen uptake, microbial activities, free air space, and the process temperature (Petric et al. …
