Anaerobic digestion of alcohol sulfate (anionic surfactant) rich wastewater – batch experiments. Part I: influence of the surfactant concentration

Bovine bile as a bio-surfactant pre-treatment option for anaerobic digestion of high-fat cattle slaughterhouse waste

“…Similar outcomes were recorded by Feitkenhauer and Meyer [19] in which alcohol sulfate, an anionic surfactant was added to batch digestions. Although the concentration of surfactant used by Feitkenhauer and Meyer [19] was much lower at 50-500 mg/L, the researchers observed significantly prolonged inhibition. Lag phase was doubled in the lowest dose, and time required to finish digestion was also extended.…”

Interaction effects of organic load and cycle time in an AsBr applied to a personal care industry wastewater treatment

“…The treatment of different wastewaters has been on the agenda of many research groups including Feitkenhauer and Meyer (2002), Ndegwa et al (2005), Li and Mulligan (2005), Mohan et al (2005Mohan et al ( , 2007, Damasceno et al (2007), Oliveira et al (2008), Bezerra et al (2007) and Canto et al (2008). One of the explanations is that the compositions of these wastewaters interfere directly with reactor stability and efficiency and may alter previously established critical parameters for a specific effluent, even when operational conditions are maintained.…”

“…These compounds will ultimately wind up and accumulate in household or industrial sewage. Relatively few studies are available that have investigated the inhibitory effects of surfactants on the anaerobic digestion process (Feitkenhauer and Meyer, 2002;Berna et al, 2007).…”
