TLDR
The higher performances on the volatile solid and pathogen reduction, and stable operation of the temperature co-phase anaerobic system might be attributable to the well-functioned thermophilic digester, sharing nutrients and intermediates for anaerilic microorganisms, and selection of higher substrate affinity an aerobic microorganisms in the co- phase system.About:

Pretreatment methods to improve sludge anaerobic degradability: a review.
Hélène Carrère,Claire Dumas,Audrey Battimelli,Damien J. Batstone,J.P. Delgenes,Jean-Philippe Steyer,Ivet Ferrer,Ivet Ferrer +7 more
TL;DR: This paper presents a review of the main sludge treatment techniques used as a pretreatment to anaerobic digestion, and it is likely that low impact pretreatment methods such as mechanical and thermal phased improve speed of degradation, while high impact methods improve both speed and extent of degradation.

Pretreatment methods to enhance anaerobic digestion of organic solid waste
Javkhlan Ariunbaatar,Javkhlan Ariunbaatar,Antonio Panico,Giovanni Esposito,Francesco Pirozzi,Piet N.L. Lens +5 more
TL;DR: In this paper, a review of pretreatment techniques to enhance the anaerobic digestion of organic solid waste, including mechanical, thermal, chemical and biological methods, is presented, in terms of their efficiency, energy balance, environmental sustainability as well as capital, operational and maintenance costs.
Journal ArticleDOI
Fate of pharmaceutical and personal care products (PPCPs) during anaerobic digestion of sewage sludge.
TL;DR: Considering the difficulty of obtaining reliable PPCPs concentrations, especially those corresponding to the fractions sorbed onto sludge, a methodology to validate the experimental data has been developed and successfully applied and no influence of SRT and temperature on PPCP removal was observed.
Journal ArticleDOI
Challenges and strategies for solid-state anaerobic digestion of lignocellulosic biomass
TL;DR: In this article, a review summarizes the challenges in SS-AD of lignocellulosic biomass and discusses the mechanisms and feasibility of potential strategies for resolving them, including pretreatment of feedstock, improvement of inoculation efficiency, co-digestion of multiple feedstocks, and upgrading biogas to higher value transportation fuels.

Waste activated sludge hydrolysis and short-chain fatty acids accumulation under mesophilic and thermophilic conditions: Effect of pH
Peng Zhang,Yinguang Chen,Qi Zhou +2 more
TL;DR: During the entire mesophilic and thermophilic fermentation the activity of methanogens was inhibited severely at acid or alkaline pHs, and the highest methane concentration was obtained at pH 7.0 in most cases.

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
Comparative process stability and efficiency of anaerobic digestion; mesophilic vs. thermophilic.
TL;DR: The comparative results of the reactor performance at steady state clearly showed the superior performance of the thermophilic non-mixed reactor with respect to lower VFA, higher gas production and volatile solids removal implying that microbial consortia proximity can alleviate the problem of poor effluent quality in thermophobic system.

Determination of bicarbonate and total volatile acid concentration in anaerobic digesters using a simple titration
G. K. Anderson,G. Yang +1 more
TL;DR: In this paper, a simple, alkalimetric method is described that can be used to determine bicarbonate and total volatile fatty acid concentrations in anaerobic digesters by a two-stage sequential titration.

Mesophilic and thermophilic anaerobic digestion of source-sorted organic wastes: effect of ammonia on glucose degradation and methane production
Claudia Gallert,Josef Winter +1 more
TL;DR: In this article, the wet organic fraction of household wastes was digested anaerobically at 37 °C and 55 °C at both temperatures for the same loading rates and was still 65% at 19 days hydraulic retention time.
