Journal ArticleDOI
Extraction of extracellular polymers from activated sludge using a cation exchange resin
TL;DR: In this article, the extraction of water soluble extracellular polymeric substances (EPS) from activated sludge was investigated, which consisted mainly of protein but also humic compounds, carbohydrates, uronic acids and DNA.
Journal ArticleDOI
Enzymatic activity in the activated-sludge floc matrix
TL;DR: The enzymatic activity of activated sludge was investigated with special emphasis on the localization of the enzymes in the sludge floc matrix, showing that the exoenzymes should be considered to be an integrated part of the EPS matrix rather than as direct indicators of the microbial activity or biomass.
Journal ArticleDOI
Changes in the composition of extracellular polymeric substances in activated sludge during anaerobic storage
TL;DR: The results showed that a fast decrease in total sludge protein and carbohydrate took place within 3 days of anaerobic storage as a result of degradation processes, which accounted for approximately 20% of the organic fraction.
Journal ArticleDOI
Deflocculation of Activated Sludge by the Dissimilatory Fe(III)-Reducing Bacterium Shewanella alga BrY.
TL;DR: The results of this study support previous research suggesting that microbial Fe(III) respiration may have an impact on the floc structure and colloidal chemistry of activated sludge.
Journal ArticleDOI
A Comparative Study of Biopolymers from a Conventional and an Advanced Activated Sludge Treatment Plant
TL;DR: In this paper, the authors compared the performance of a traditional and an advanced activated sludge treatment plant performing biological N and P removal using an ion exchange resin (DOWEX in Na-form).
