TLDR
In this paper, a literature review of anaerobic digestion of municipal wastewater sludges is presented, focusing on the fundamentals of the process and setting forth a checklist for review of key process factors including retention time, mixing, pH, temperature, nutrients, toxic materials and feed characteristics.Abstract:
This paper presents a literature review of anaerobic digestion of munidpal wastewater sludges. The paper focuses on the fundamentals of anaerobic digestion, setting forth a checklist for review of key process factors including: retention time, mixing, pH, temperature, nutrients, toxic materials, and feed characteristics. Major areas discussed are the microbiology and biochemistry of digestion, kinetics of digestion, environmental factors of concern, process performance indices, product stability, and laboratory and pilot studies on digestion. Although the text is aimed at digestion of municipal sludges, the fundamentals are sufficiently general to permit extrapolation to decomposition of other organics.read more

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.

Solid-state anaerobic digestion for methane production from organic waste
TL;DR: The principles and applications of the solid-state anaerobic digestion (SS-AD) process are reviewed in this article, and the variation in biogas production yields of different feedstocks is discussed as well as the need for pretreatment of lignocellulosic biomass such as crop residues and energy crops.

The Characterization of Feces and Urine: A Review of the Literature to Inform Advanced Treatment Technology
TL;DR: Variation in the volume and composition of urine is caused by differences in physical exertion, environmental conditions, as well as water, salt, and high protein intakes, which should always be considered if the generation rate, physical, and chemical composition of feces and urine is to be accurately predicted.

Anaerobic co-digestion of algal sludge and waste paper to produce methane.
Hong-Wei Yen,David E. Brune +1 more
TL;DR: Results suggested an optimum C/N ratio for co-digestion of algal sludge and waste paper was in the range of 20-25/1.
