Journal ArticleDOI
Volatile fatty acids production from food waste: effects of pH, temperature, and organic loading rate.
TL;DR: The effects of pH, temperature, and organic loading rate (OLR) on the acidogenesis of food waste have been determined and the percentage of acetate and valerate increased as OLR increased, whereas a high OLR produced a lower percentage of propionate and butyrate.
Journal ArticleDOI
Performances of anaerobic co-digestion of fruit & vegetable waste (FVW) and food waste (FW): Single-phase vs. two-phase
Fei Shen,Fei Shen,Hairong Yuan,Yunzhi Pang,Shulin Chen,Baoning Zhu,Dexun Zou,Yanping Liu,Jingwei Ma,Liang Yu,Xiujin Li +10 more
TL;DR: Comparison of these two systems with bioenergy recovery revealed that two-phase system overall presented higher bioenergy yield than single-phase, and more stable operation, and higher OLR treatment capacity.

Optimization of anaerobic acidogenesis by adding Fe0 powder to enhance anaerobic wastewater treatment
TL;DR: In this article, a novel strategy for enhancing anaerobic wastewater treatment via dosing Fe powder (40 grams) in an acidogenic reactor (2L) is described, and the results showed that the hydrolysis/fermentation was accelerated by Fe dosing.

Improving anaerobic digestion of easy-acidification substrates by promoting buffering capacity using biochar derived from vermicompost.
Dou Wang,Jing Ai,Fei Shen,Gang Yang,Yanzong Zhang,Shihuai Deng,Jing Zhang,Yongmei Zeng,Chun Song +8 more
TL;DR: Biogas release was delayed for 10-days accompanying rapid pH decrease in CM digestion with VC, which reflected acid-buffering of biochar played a crucial role on improving anaerobic digestion.

Comparison of anaerobic digestion characteristics and kinetics of four livestock manures with different substrate concentrations.
Kun Li,Ronghou Liu,Chen Sun +2 more
TL;DR: The Cone model showed a better fit to the experiment data and the calculated parameters indicated that anaerobic digestion of manures at higher loading has longer lag phase and lower hydrolysis rate.

Standard methods for the examination of water and wastewater
TL;DR: The most widely read reference in the water industry, Water Industry Reference as discussed by the authors, is a comprehensive reference tool for water analysis methods that covers all aspects of USEPA-approved water analysis.
Journal ArticleDOI
Optimisation of the anaerobic digestion of agricultural resources.
TL;DR: Current optimisation techniques associated with anaerobic digestion are reviewed and possible areas where improvements could be made are suggested, including the basic design considerations of a single or multi-stage reactor configuration, the type, power and duration of the mixing regime and the retention of active microbial biomass within the reactor.
Journal ArticleDOI
Kinetics of anaerobic treatment: A critical review
TL;DR: The fundamentals of microbial kinetics and continuous culture models are presented and the effect of temperature and inhibitors on the intrinsic kinetic rates is discussed, and Stoichiometric and bioenergetic considerations are reviewed.
Journal ArticleDOI
Ethanol‐type fermentation from carbohydrate in high rate acidogenic reactor
TL;DR: It has been shown that the production of propionic acid is not always related to high hydrogen partial pressure, and when the operating pH was increased to 5.5, the yield of Propionic acid became significant.

Developments in Anaerobic Stabilization of Organic Wastes - The Two-Phase Concept
F G Pohland,S Ghosh +1 more
TL;DR: In this article, the two-phase concept of anaerobic stabilisation of organic wastes is proposed. But the two phases are different in different ways and cannot be used simultaneously.
