Interaction Between Perfluorooctanoic Acid and Aerobic Granular Sludge

Water Research, 2020
The increasing use of perfluorooctanoic acid (PFOA) raises concerns about its potential toxicity to the environment. However, the interaction between PFOA and aerobic granular sludge has never been documented.

Aerobic Granular Sludge – State of the Art

Water Science and Technology, 2007
In September 2006, preliminary to the IWA biofilm conference, a second workshop about aerobic granular sludge was held in Delft, The Netherlands, of which a summary of the discussion outcomes is given in this paper. The definition of aerobic granular sludge was discussed and complemented with a few additional demands.

Aerobic Granular Sludge—A Case Report

Water Research, 1999
Abstract Aerobic granular sludge was observed in a Sequencing Batch Reactor (SBR) in which a synthetic urban wastewater containing sodium acetate as an organic substrate was fed, and dissolved oxygen (DO) was controlled at low concentration (0.7–1.0 mg/l) Microscope examination showed that the morphology of the granules was nearly spherical (0.3–0.5 ...

Direct start-up of aerobic granular sludge system with dewatered sludge granular particles as inoculant

Journal of Environmental Management, 2022
AGS is a promising technology for engineering applications in the biological treatment of sewage. New objectives are to skip the conventional granulation step, so as to directly integrate it into a continuous-flow reactor. This study proposed a method for integrating dewatered sludge granular particles ( DSGPs ) into a new patented aerobic granular ...

Characteristic of Granular Sludge Bed and Granular Sludge in Interior Diversion Expanded Granular Sludge Bed

Advanced Materials Research, 2013
The interior diversion expanded granular sludge bed was concurrently operated for 140d to study the characteristic of the granular sludge bed. The influent COD concentration varied from 2000mg/L to 22300 mg/L, hydraulic retention time was maintained constant at 24 h and the organic loading rate was changed through a change in substrate concentration ...

Rheological and Fractal Characteristics of Granular Sludge in an Upflow Anaerobic Reactor

Water Research, 2006
The rheological and fractal characteristics of the granular sludge in an upflow anaerobic sludge blanket (UASB) reactor were investigated in this study. The influences of sludge concentration and temperature on the rheological properties of the granular ...

Characterization of a hydrogen‐producing granular sludge

Biotechnology and Bioengineering, 2002
AbstractThis study demonstrated that hydrogen‐producing acidogenic sludge could agglutinate into granules in a well‐mixed reactor treating a synthetic sucrose‐containing wastewater at 26°C, pH 5.5, with 6 h of hydraulic retention. A typical matured granule is 1.6 mm in diameter, 1.038 g/mL in density, 11% in ash content, and over 50 m/h in settling ...

A Settling Model for Full-Scale Aerobic Granular Sludge

Water Research, 2020
The settling behavior of aerobic granular sludge (AGS) in full-scale reactors is different from the settling of normal activated sludge. Current activated sludge models lack the features to describe the segregation of granules based on size during the ...
