Extraction of Structural Extracellular Polymeric Substances from Aerobic Granular Sludge
To evaluate and develop methodologies for the extraction of gel-forming extracellular polymeric substances (EPS), EPS from aerobic granular sludge (AGS) was extracted using six different methods (centrifugation, sonication, ethylenediaminetetraacetic acid (EDTA), formamide with sodium hydroxide (NaOH), formaldehyde with NaOH and sodium carbonate (Na2CO3) with heat and constant mixing). AGS was ...
متن کاملAdvanced sludge treatment affects extracellular polymeric substances to improve activated sludge dewatering.
The management of wastewater sludge, now often referred to as biosolids, accounts for a major portion of the cost of the wastewater treatment process and represents significant technical challenges. In many wastewater treatment facilities, the bottleneck of the sludge handling system is the dewatering operation. Advanced sludge treatment (AST) processes have been developed in order to improve s...
متن کاملCharacterization and Molecular Identification of Extracellular Polymeric Substance (EPS) Producing Bacteria from Activated Sludge
The aim of this study was identification and characterization of highly efficient Extracellular Polymeric Substance (EPS) producing bacteria in activated sludge. Among 74 isolated bacteria, 20 EPS-producing bacteria were obtained from wastewater treatment plant of Bojnourd. EPS extraction was performed using absolute ethanol after glucose-enriched culture. Dry weight, concentration, and the rat...
متن کاملExtraction of enzymes from activated sludge
About 60–70% of the organic matter contained by domestic wastewater is formed by lipids and proteins. The microorganisms that are able to degrade this organic matter produce hydrolytic enzymes that cannot be produced by standard cultivation techniques. The extraction methods have to include detergents or ionic exchange resins to recover qualitatively and quantitatively the enzyme activity. In t...
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...
