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 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 کاملInfluence of Diphenyloxide Disulfonate Surfactants on Biodegradation of Hydrocarbons
Testing was conducted with anionic diphenyloxide disulfonate (DPDS) surfactants (C12 and C16 alkyl moieties) with naphthalene in aqueous systems and phenanthrene in soil systems to investigate the influence of these surfactants on biodegradation of hydrocarbons. A potential for enhancement in the degradation of naphthalene was seen in C12-DPDS amended assays at low surfactant concentrations, pr...
متن کاملBiodegradation of anionic surfactants by isolated bacteria from activated sludge
*Corresponding author, Email: [email protected] Tel: +9821 2264 1842; Fax: +9821 2266 6016 ABSTRACT: Sodium dodecyl sulphate, (SDS) is an anionic surfactant that widely used all over the world. They will eventually end-up and accumulate in household or industrial sewage. Due to their high foaming capabilities, which can cause numerous problems in sewage treatment facilities as well as direct t...
