2019/7/26/ · Water below the critical conditions does not dissolve sewage sludge components of various organic matters, while water possesses the miscibility with organic materials under super critical conditions [2]. This characteristic leads to a rapid rate and tar-free gasification to produce gas-rich products including H 2, CH 4, CO, and CO 2 [73

2019/11/1/ · 1. Introduction. The treatment of sewage sludge (SS) has remained a thorny issue until now. Because of its high organic matter content, anaerobic digestion (AD) is widely used for SS treatment and can produce volatile fatty acids (VFAs) or methane (Appels et al., 2008; Chen et al., 2007).VFAs can act as superior carbon sources for
2022/7/1/ · 1. Introduction. The approach of the circular economy is based on the reuse of the produced waste to give them a second life and thus recover bioproducts with high added value (Battista et al., 2020).Organic food waste, as well as the sewage sludge produced from domestic wastewater treatment plants (WWTPs) are the two biggest

2020/1/1/ · The disposal cost of sewage sludge usually accounts for around 50% of the total operational cost in WWTPs (Appels et al., 2008).With the vast amount of the generated sludge from WWTPs, which also contains a substantial quantity of organic matter, therefore, much attention has been focused on the reuse and recycling of the valuable
2010/10/1/ · The cost of producing 120 tons of sewage sludge compost included using a fermenter (rental fee: US$ 20), operating fee including electric charges (US$ 420), heavy machinery operating fee (including excavator: US$ 500), the material cost (almost sawdust: US$ 4500) and US$ 720 for personal expenses (the rental fee of a fermenter was much
2023/12/15/ · Sewage sludge collected from a pilot scale WWTP was used to produce VFA, select the PHA producers' microorganisms and stress the PHA

2009/7/11/ · The biomass containing dry sludge cake was collected by filtering the fermentation broth (treated sludge) and dried at 105°C with 24 and 48 h for shake flask and fermenter experiment respectively. The supernatant was used for analysis after centrifuging the fermented broth at 3000 rpm for 30 min.
2021/7/1/ · The effect of CO 2 enrichment in sewage sludge anaerobic digestion (AD) as a potential strategy to improve the biogas yield was assessed at increasing organic loading rates (OLR). Effects on process performance and resilience were evaluated in long-term continuous AD experiments at lab-scale. The specific methane production (SMP)
High-temperature good oxygen fermenter [123 ] Sludge treatment is the process of sludge reduction, stabilization, and harmless. As the sewage treatment rate increases, more
Here the role of microplastic size on dissolved organic matter, leaching compounds and microbial community during anaerobic sludge digestion was evaluated. Compared to that without the addition of polyvinyl chloride (PVC), during the 30 days' incubation, the anaerobic sludge digestion by adding PVC …
