Oxygen is an important parameter for organic-waste composting, and continuous control of the oxygen in a composting pile may be beneficial. The oxygen consumption rate can be used to measure the degree of biological oxidation and decomposition of organic matter. However, without having a real-time online device to monitor oxygen levels in the composting pile, the adjustment and optimization of
Automatic compost machine is a type of auxiliary equipment for material fermenting process, featuring a fully automatic control system. It is widely applied in different kinds of organic fertilizer production plants for material turning in the material fermenting process. This type of composting facility is composed of heavy cranes stretching
Because of the complicated interaction of the sludge compost components, it makes the compost maturity degree judging system appear the non-linearity and uncertainty. According to the physical circumstances of sludge compost, a compost maturity degree modeling method based on wavelet neural network is presented.
Jun 18, 2019 · In this paper, we discuss the effect sewage sludge (SS) application has on the contamination of polycyclic aromatic hydrocarbons in fertilized soils and groundwater. Morver, the contents of these compounds in plant biomass was analyzed. For six months, composted sewage sludge was introduced into sandy soil. The research was conducted under lysimetric experiment conditions with the possibility
Aug 17, 2021 · In this study, the operations of six industrial composting facilities that process municipal solid waste and sewage sludge were evaluated from the point of view of the sanitation achieved and the
Apr 1, 2023 · Co-composting is an efficient solid waste management method that helps to manage various solid wastes (i.e., poultry waste, animal waste, food waste, agricultural waste, municipal solid waste, industrial sludge, sewage, etc.) and turn them into valuable products, which can increase soil fertility by acting as a soil conditioner.
Aug 30, 2023 · Complementary characteristics of rice straw (RS) and sewage sludge (SS) create a suitable mixture to be used in a composting process. This work studies industrial-scale RS and SS composting to assess both its viability and optimization. Windrow composting was conducted during two seasons.
Comprehensive reference examining activated sludge technologies in industrial wastewater treatment, combining a theoretical framework with practical methodologies Application of Sewage Sludge in Industrial Wastewater Treatment provides a roadmap to the methodologies for the treatment of industrial wastewaters from several major sectors integrating theory and practice, highlighting the
Mar 10, 2024 · Nutrient-rich compost suitable for agricultural purposes and land reclamation can be obtained with aerobic stabilization (composting) of sewage sludge with plant biomass. Composting is a biological decomposition of organic material under aerobic conditions through the enzymatic activity of several microorganisms ( Aydın Temel, 2023 ).
Therefore, industrial-scale sewage sludge composting was shown to be an effective tool for the elimination of indicator strains of fecal contamination resistant to certain antibiotics in routine use. Thus, it contributed to the reduction of the spread of ARGs in environmental microbiomes, as well as the transfer of the same in the food chain.
The automatic compost machine from SEEC is a commercial & industrial composting equipment for large scale organic wastes fermentation operation. It is used for fermenting and turning of organic wastes such as livestock and poultry manure, sludge waste, sugar plant filter sludge, straw sawdust, brewers’ spent grain, spent mushroom compost and
May 14, 2021 · Due to the fact that compost is a valuable fertilizer that serves principally as a source of macronutrients, composting is one of the preferred of management of organic waste, including municipal sewage sludge. However, due to its high moisture content and low C/N ratio, sewage sludge cannot be composted alone. This study investigated the usefulness of waste willow-bark (WWB) (after
Sewage sludge is the residual, semi-solid material that is produced as a by-product during sewage treatment of industrial or municipal wastewater. The term "septage" also refers to sludge from simple wastewater treatment but is connected to simple on-site sanitation systems, such as septic tanks . When fresh sewage or wastewater enters a
Apr 1, 2019 · Thus, a well-operated sewage sludge composting plant can better reduce the generation of VOCs than facilities lacking good operating conditions (Saldarriaga et al., 2014). The total amount of VOCs was 142.2 ± 86.8–2595.7 ± 1367.3 μg.m −3 in the entire composting process, and the sum of the individual VOC species was calculated from the
Jul 15, 2021 · The utilization of nutrients in sewage sludge partly alleviates the economic and environmental constraints, and the composting process has been proved a cost-efficient and simple approach for the recycling of sewage sludge. During the bio-oxidative process, the thermophilic phase is considered to be the most effective stage for the biodegradation of organic matter in sewage sludge composting
