Biomass adaptation over anaerobic co-digestion of sewage sludge and trapped grease waste
TLDR
The results indicate that a slow increase in the grease waste dose could be a strategy that favours biomass acclimation to fat-rich co-substrate, increases long chain fatty acid degradation and reduces the latter's inhibitory effect.About:

Anaerobic Codigestion of Municipal Wastewater Treatment Plant Sludge with Food Waste: A Case Study.
TL;DR: Results confirm that codigestion has great potential in improving the methane yield of SS and suggest the biosolids meet the guidelines for use as a soil conditioner.
Journal ArticleDOI
Effects of temperature and organic loading rate on the performance and microbial community of anaerobic co-digestion of waste activated sludge and food waste.
TL;DR: Results showed that the performance of co-digestion system was distinctly influenced by temperature and organic loading rate (OLR) in terms of gas production rate, methane yield, volatile solids removal efficiency and the system stability.
Journal ArticleDOI
Review of pre-treatments used in anaerobic digestion and their potential application in high-fat cattle slaughterhouse wastewater.
TL;DR: A review of the literature in the field of pre-treatment of wastewaters and subsequent anaerobic digestion is presented in this article with an emphasis on digestion of wastes high in fat, oil and grease.

Overview of key operation factors and strategies for improving fermentative volatile fatty acid production and product regulation from sewage sludge
Wei Fang,Xuedong Zhang,Panyue Zhang,Jijun Wan,Hongxiao Guo,Dara S.M. Ghasimi,Xavier Carol Morera,Tao Zhang +7 more
TL;DR: According to published studies, it is concluded that some pretreatments such as alkaline and thermal pretreatment are the most effective ways to enhance VFA production from sewage sludge.

Standard methods for the examination of water and waste water.
TL;DR: Alkalinity measurements are used in the interpretation and control of water and wastewater treatment processes and can be interpreted in terms of specific substances only when the chemical composition of the sample is known.
Journal ArticleDOI
Principles and potential of the anaerobic digestion of waste-activated sludge
TL;DR: In this article, the authors extensively review the principles of anaerobic digestion, the process parameters and their interaction, the design methods, the biogas utilisation, the possible problems and potential pro-active cures, and the recent developments to reduce the impact of the problems.

Thermophilic anaerobic digestion of livestock waste: the effect of ammonia
TL;DR: A stable digestion of cattle manure could be maintained with ammonia concentrations up to 6 g N/l after 6 months of operation, however, the methane yield was reduced and the concentration of volatile fatty acids increased from 1 to 3 g/l as acetate, compared to controls with an ammonia concentration of 2.5 gN/l.

Fundamentals of Anaerobic Digestion of Wastewater Sludges
Gene F. Parkin,William F. Owen +1 more
TL;DR: 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.

Hydrolysis kinetics in anaerobic degradation of particulate organic material: an overview.
TL;DR: It has been shown that models in which hydrolysis is coupled to the growth of hydrolytic bacteria work well at high or at fluctuant organic loading, and new developments in spatially distributed models are considered fundamental to provide new insights in this complex process.
