Anaerobic Biodegradation of Detergent Surfactants
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...
متن کاملOxygen Effects on Biodegradation of Fuels in a Corroding Environment
Experiments were designed to evaluate biodegradation of plantand petroleum-based fuels and blends exposed to seawater under anaerobic conditions. The experimental set-up included natural aerobic seawater, fuel and unprotected carbon steel coupons, simulating a potential fuel storage situation. Corrosion was due to microbiologically produced sulfides reacting with carbon steel. There were few di...
متن کاملUltimate biodegradation of alkylphenol ethoxylate surfactants and their biodegradation intermediates.
The ultimate biodegradation of the commercial products nonylphenol ethoxylates (NPE9), octylphenol ethoxylates (OPE9), and their biodegradation intermediates, NPE1.5, OPE1.5, NP, and OP, was measured using conventional methods. The extent of biodegradation was also determined by gas chromatography/mass spectrometry (GC/MS) and high-performance liquid chromatography (HPLC) analysis of metabolite...
متن کاملAnaerobic 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...
متن کاملSurfactants in the environment.
Surfactants are a diverse group of chemicals that are best known for their wide use in detergents and other cleaning products. After use, residual surfactants are discharged into sewage systems or directly into surface waters, and most of them end up dispersed in different environmental compartments such as soil, water or sediment. The toxic effects of surfactants on various aquatic organisms a...
