2019/2/1/ · Integrating microbial electrolysis cell into an anaerobic digestion system allowed for electrochemical regulation of co-fermentation of food waste and municipal sludge which resulted in the
Energy Efficiency Economics of Conversion of Biogas from the Fermentation of Sewage Sludge to Biomethane as a Fuel for Automotive Vehicles
2019/8/9/ · One example of the fermentation process being intensified entails co-fermentation of sewage sludge with other organic waste, via the so-called co-digestion process (Masłoń and Tendera 2017; Mata-Alvarez et al. 2014). This article presents matters relating to the production of biogas at the wastewater treatment plant in Zamość (Poland).
2020/4/1/ · During the acidogenic fermentation converting waste activated sludge (WAS) into short-chain fatty acids (SCFA), hydrolysis of complex organic polymers is a limiting step and the transformation of
2024/1/31/ · Special Issue Information. Dear Colleagues, In recent years, volatile fatty acid (VFA) production through anaerobic fermentation of sewage sludge, instead of methane production, has been regarded as a high-value and promising roadmap for sludge stabilization and resource recovery. Compared to methane, VFAs have a higher value
2024/2/1/ · Anaerobic fermentation is widely installed to recovery valuable resources and energy as CH 4 from waste activated sludge (WAS), and its implementation in developing countries is largely restricted by the slow hydrolysis, poor efficiency, and complicate inert components therein. In this study, enzyme-enhanced fermentation was
2022/12/1/ · 1. Introduction. Resources recovery from solid wastes has become increasingly urgent and attractive owing to the dual benefits of waste management and value-added generation [1].The two major solid wastes, food waste (FW) and sewage sludge (SS), face major challenges in appropriate disposal [2].Approximately 1.3 billion
The effect of sewage sludge (SWS) addition on the H2 fermentation of food waste (FW) was investigated. It was found that a slight addition of SWS (10:1=FW:SWS on a COD basis) significantly enhanced the H2 fermentation performance, not only increasing the total amount of H2 produced but accelerating the whole reaction, shortening the lag period,
2014/10/1/ · VFA synthesis and recovery from sewage sludge, food and fermentation waste is a potential approach for chemical oxygen demand (COD) removal and carbon capture from the waste streams (Longo et al
In this paper, a new fermentation method was employed to significantly produce the propionic acid-enriched VFA from the co-fermentation liquid of sewage sludge and food waste: including (1) mixing food waste with sludge in the anaerobic digester (the first stage) and (2) separating the mixture, sterilizing the first stage liquid and fermenting
2022/10/1/ · 50.3 M tons of wastes are annually produced at urban level in the EU-27. Sewage sludge, Organic Fraction of Municipal Solid Wastes (OFMSW) and food industrial wastewaters, are the major typologies of wastes produced at urban level. OFMSW and sewage sludge account for the 28 % and 23 % of the EU-27 wastes streams, respectively.
2017/8/24/ · Co-digestion of food waste and sewage sludge (92.5 mL H 2 /g VS) resulted a 90% improvement of the hydrogen production yield compared to solo food waste fermentation (48.7 mL H 2 / g VS) [50].
A fermenter is a reactor or unit process found on site at a wastewater treatment plant in which complex particulate and soluble substrates present in the sludge and wastewater
2024/2/29/ · In the present study, a novel strategy for the effective production of hydrolase via fermentation of food waste was developed to improve methane production
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
