Anaerobic Biodegradation of Detergent Surfactants [PDF]
Materials, 2009 Detergent surfactantscan be found in wastewater in relevant concentrations. Most of them are known as ready degradable under aerobic conditions, as required by European legislation. Far fewer surfactants have been tested so far for biodegradability under anaerobic conditions.

Effect of Dispersion Treatment on Dairy Waste Activated Sludge to Hasten the Production of Biogas
Frontiers in Energy Research, 2019 The solubilization potential of biological pre-treatment for waste activated sludge (WAS) is limited due to the floc structure of the WAS. Extra polymeric substances (EPS) are responsible for floc formation.

Limits of anaerobic biodegradation
Water Science and Technology, 2002 The main factors responsible for anaerobic recalcitrance are reviewed. Anaerobic recalcitrance is associated with hydrocarbons lacking functional groups, branched molecules (gasoline oxygenates), aromatic amines and aromatic sulfonates. The most recalcitrant compounds are high molecular weight non-hydrolyzable polymers such as plastic, lignin and humus,

Anaerobic biodegradation of cyanide under methanogenic conditions [PDF]
Applied and Environmental Microbiology, 1991 Upflow, anaerobic, fixed-bed, activated charcoal biotreatment columns capable of operating at free cyanide concentrations of greater than 100 mg liter-1 with a hydraulic retention time of less than 48 h were developed. Methanogenesis was maintained under a variety of feed medium conditions which included ethanol, phenol, or methanol as the primary ...
