Importance of Extracellular Polymeric Substances on Fouling in Membrane Bioreactor
This paper aims to broaden a better understanding of extracellular polymeric substances (EPS) and its impact on fouling in membrane bioreactor (MBR). Some fundamental knowledge about EPS and MBR fouling was covered in this paper in several aspects including definition of EPS, evaluation of EPS, influencing factors on EPS production and responsibility of EPS on MBR fouling mechanisms.
متن کاملInfluences of Extracellular Polymeric Substances on the Dewaterability of Sewage Sludge during Bioleaching
Extracellular polymeric substances (EPS) play important roles in regulating the dewaterability of sludge. This study sought to elucidate the influence of EPS on the dewaterability of sludge during bioleaching process. Results showed that, in bioleaching system with the co-inoculation of Acidithiobacillus thiooxidans TS6 and Acidithiobacillus ferrooxidans LX5 (A. t+A. f system), the capillary su...
متن کاملEffect of Extracellular Polymeric Substances on Surface Properties and Attachment Behavior of Acidithiobacillus ferrooxidans
Bacterial contact leaching of ores is more effective than non-contact leaching. Adhesion is the first step for leaching bacteria to form a biofilm on a mineral surface. Extracellular polymeric substances (EPS) are pivotal for mediating bacterial adhesion to a substratum. In order to clarify the role of EPS, we measured the adhesion forces between chalcopyrite-, sulfuror FeSO4·7H2O-grown cells o...
متن کاملStudies on the Bioremediation of Chromium ( VI ) Through Bioleaching by Thiobacillus ferrooxidans
Chromium (VI) is the toxic substances that are released from the electroplating and the tannery industries, it is caused serious environmental problems and is toxic to organisms. These toxic substances are effectively remediated by microorganisms such as Thiobacillus ferrooxidans. Their toxic effect is minimized by these types of microorganisms. These properties can be effectively studied in St...
متن کاملOptimization of Carbon and Nitrogen Sources for Extracellular Polymeric Substances Production by Chryseobacterium indologenes MUT.2
Background: Bacterial Extracellular Polymeric Substances (EPS) are environmental friendly and versatile polymeric materials that are used in a wide range of industries such as: food, textile, cosmetics, and pharmaceuticals. To make the production process of the EPS cost-effective, improvements in the production yield is required which could be implemented through application of processes such a...
