Anaerobic Biodegradation of Detergent Surfactants
نویسندگان
چکیده
Detergent surfactants can 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. The natural environment is predominantly aerobic, but there are some environmental compartments such as river sediments, sub-surface soil layer and anaerobic sludge digesters of wastewater treatment plants which have strictly anaerobic conditions. This review gives an overview on anaerobic biodegradation processes, the methods for testing anaerobic biodegradability, and the anaerobic biodegradability of different detergent surfactant types (anionic, nonionic, cationic, amphoteric surfactants).

Anaerobic Biodegradation of Surfactants – Scientific Review
The anaerobic biodegradation of surfactants is used as an acceptability criterion in some environmental pieces of legislation (eco-label, risk assessment, etc.), without a proper evaluation of the relevance of such a characteristic. Available screening test methods to assess the anaerobic biodegradation do not simulate the real conditions prevailing in these anaerobic compartments but rather re...

Aquatic environmental monitoring of detergent surfactants.
Since 1998, Japan Soap and Detergent Association has been continuously evaluating the concentrations of four surfactants used in household detergents and fabric conditioners in river surface water: linear alkylbenzene sulfonate (LAS), polyoxyethylene alkyl ether (AE), alkyldimethylamine oxide (AO) and dialkyl dimethylammonium chloride (DADMAC) in Japanese urban rivers, in order to assess the ri...

An analytical method was elaborated for simultaneous extraction and determination of fluorinated anionic and non-ionic surfactants in sewage sludge. Surfactant compounds were determined by liquid chromatography-mass spectrometry (LC-MS) after Soxhlet extraction, hot steam extraction and pressurised liquid extraction (PLE) using spiked sludge samples. PLE in a multiple-step procedure consisting ...

-Anaerobic biodegradation and inhibitory effects of nonionic and anionic surfactants on methanogenic fermentation were tested in incubation experiments with anoxic sediment samples and sewage sludge. Alkylsulfonates and alkylbenzenesulfonates were not degraded but inhibited methanogenesis from sludge constituents at concentrations 1> 10 mg l-k Sodium dodecylsulfate was at least partly degraded ...
