2024/4/30/ · The relevant studies will provide new sights into sludge fermentation and guidance for sludge disposal. We are inviting research papers and reviews about novel insights on sludge fermentation. The aim of this Special Issue is to provide an insight into the latest findings of sludge fermentation, including the biologically volatile fatty acids
2021/4/1/ · Sludge fermentation and anaerobic digestion are the most widely used for stabilising sewage sludge [5], and they lead to the production of useful the soluble carbohydrate concentration in the pretreated sludge fermentation systems reached maximum values of 209, 285, 295, 309, and 287 mg/L. Compared with the
USA Sludge matches the feed-rate to the demand. This is best understood from the point-of-view of “Value-to Value”. In other words, we strive to seed a proper amount of Revive complex into the fermenting tank, and after a 24-hour period, begin releasing the solution into the waste stream, attempting to match the demand.
Electro-fermentation (EF) was combined with anaerobic fermentation (AF) to promote medium-chain fatty acid (MCFA) from sewage sludge. Results showed that EF at
2023/12/1/ · A sedimentation tank with a working volume of approximately 6 m 3 was connected to the CSTR for sludge sedimentation, and the bottom sludge was returned to the CSTR through a submersible sewage pump. Each cycle of the NF-SBR lasted for 8 h and consisted of 5 periods: 40 min feeding, 1–3 h aeration, 40 min settling, 40 min
2023/12/8/ · In this study, an algal–bacterial symbiotic consortium was integrated with the sediment microbial fuel cell (SMFC) to construct an algal–bacterial cathode SMFC (AC-SMFC) for excess sewage sludge treatment and electricity generation. A bacterial cathode SMFC (BC-SMFC) and a static settling system (SS-system) were used as controls.
2022/12/1/ · Optimal mixing ratio of food waste (FW) and sewage sludge (SS) was 3:1 based on COD. • Highest MCFAs concentration was 10441.31 mg COD/L by co-fermentation of FW and SS. • n-Caproate was the most abundant and accounted for 60.28 % of three MCFAs. • The chain elongation system was driven by lactate as electron donors.
2023/7/15/ · The pretreatment of sewage sludges are used to support the process of methane fermentation (Patinvoh et al. 2016; Wluka et al. 2021; Nguyen et al. 2021; Machnicka and Grübel 2023 ). used for the pretreatment of biomass for biogas production on a large scale are chemical, or physical, including thermal and
2024/5/1/ · This study evaluated a synergetic waste activated sludge treatment strategy with environmentally friendly zero-valent iron nanoparticles (Fe 0) and peroxysulfate.To verify the feasibility of the synergistic treatment, Fe 0, peroxysulfate, and the mixture of peroxysulfate and Fe 0 (synergy treatment) were added to different sludge fermentation
2017/8/24/ · For example, the hydrogen production from solo sewage sludge fermentation was low (11.2 mL/g VS), while the yield increased to 20.8, 32.0, and 51.7 mL/g VS when cofermented with fallen poplar
2022/10/1/ · MCFAs were produced from complex organics through two-stage fermentation process, i.e. acidification process and CE process. Fig. 1 A shows the acids formation in different fermentation groups during the acidification process. The mono-fermentation of sewage sludge achieved the highest cumulative acids production of
2023/5/15/ · Longo et al. (2015) conducted a pilot test for the production of SCFAs from sewage sludge by alkaline fermentation and subsequent membrane filtration, and the removal efficiency of TN and TP was increased by 19 % and 39 %, respectively, using membrane-filtered SAFL as the carbon source for BNR compared to using acetic acid as
