In the bacteria-algae (BA) system, the amount of oxygen produced by the algae is always insufficient for the organic carbon degradation, resulting in less inorganic carbon (IC) production. Meanwhile, the conventional extra aeration method always causes CO2 stripping and IC loss. Both two reasons limited the algae boosting. Membrane aeration (MA) has the excellent

2020/5/1/ · The aerated static pile (ASP) composting refers to one of the systems used for biomass bioconversion without mechanical manipulation. In the ASP composting system, the composting mixture remains static and aeration is maintained at an appropriate level by pushing (positive pressure) or pulling (negative pressure) of air through the composting pile.

2024/3/15/ · The effect of EAs on ARGs and microbial community assembly were stochastic processes. Composting stage and EAs jointly reduced the association between ARGs and MGEs in the composting system. The reduction of ARGs attributed to a decreased abundance of potential pathogenic ARG-associated hosts and diminished associations with MGEs.

2023/11/15/ · The application potential of composting depends greatly on the quality and efficiency of the compost [11].Recently, it has been shown that the level of organic matter metabolic of the microbiome is affected by regulating process parameters such as C/N, moisture, porosity, pH and aeration rate, which can improve the conversion of dissolved organic matter

2023/3/1/ · Composting is the most adaptable and fruitful method for managing biodegradable solid wastes; it is a crucial agricultural practice that contributes to recycling farm and agricultural wastes.

Utilizing external aeration to enhance the performance of microalgae-bacteria symbiosis (ABS) system has been extensively studied. However, inappropriate aeration damaged ABS system stability. A nighttime aeration mode (NA-ABS) in different aeration intensities (20, 50, 100 mL/min) was adopted to compare to continuous aeration microalgae-bacteria symbiosis (CA-ABS)

ECS has designed and provided the air distribution, control, and monitoring systems for dozens of biofilters at large composting facilities and processing buildings such as MRF’s. weather, and entering air conditions impact the moisture level. For composting only applications, blowing humid exhaust air works well to keep the humidity high ...

2022/2/1/ · The introduction of turning machines and aeration systems has improved the treatment efficiency of compost per unit area with continuous melioration in composting (Soto-Paz et al., 2019), but turning and aeration also caused a large amount of nutrient loss and odor emissions (Jiang et al., 2015), which is highly exhibited in the

One of them was static, and the other was continuously rotated at 3 rpm; each was supplied with continuous aeration. Compost temperatures (T c) were measured throughout the composting process; the moisture content (MC) and carbon/nitrogen ratio (C/N) were measured at the beginning and end of the experiment. The quality and stage of compost were

The selection of a centrifugal fan for compost aeration involves a thorough evaluation of both the compost system’s needs and the fan’s features. By carefully considering these elements, you can ensure that you choose a fan that not only meets the immediate aeration needs but also contributes to the long-term efficiency, productivity, and

Biochar is found to have a total pore volume and a pore surface area that are larger than those of most soils, with its total surface area being ∼5 times larger than that of the average soil. 81 A large surface area of biochar can contribute to the improvement of water retention in soil, allowing biochar to retain moisture in micro- and

2023/11/1/ · Mature compost reduced the total global warming potential (GWP) by 25.91 % via inhibiting the activity of bacteria related to the production of CH 4 and N 2 O. Functional Annotation of Prokaryotic Taxa (FAPROTAX) further revealed that mature compost addition increased relative abundance of bacteria related to multiple carbon (C) cycle functions
