Sustainability | Free Full-Text | Sewage Sludge Management

Apr 1, 2023 · One of the most pressing environmental problems worldwide is sewage sludge (SS) management. Every year, wastewater volume increases and thus, the amount of SS produced increases as well. The disposal of SS in landfills, as practiced in many countries, is not a sustainable solution. Instead, SS, rich in organic matter and other nutrients, can be used as an alternative soil additive or

Antibiotic Resistome and Its Association with Bacterial

Composting is widely used for recycling of urban sewage sludge to improve soil properties, which represents a potential pathway of spreading antibiotic resistant bacteria and genes to soils. However, the dynamics of antibiotic resistance genes (ARGs) and the underlying mechanisms during sewage sludge composting were not fully explored. Here, we used high-throughput quantitative PCR and 16S

Sewage sludge treatment - Wikipedia

Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and

Oxygen Monitoring Equipment for Sewage-Sludge Composting and

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

Role of Temperature in Sludge Composting and - Springer

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
