Extracellular Polymeric Substances from Aerobic Granular Sludge: Implications for Agricultural Use in Foliar Fertilization

This study explores the potential use of extracellular polymeric substances (EPS), commercially known as Kaumera Nereda Gum®, extracted from aerobic granular sludge (AGS), for foliar fertilization in agriculture. Koppert, a company specializing in sustainable agricultural products, is interested in using Kaumera Nereda Gum® for its...

Modelling the influence of physical properties of extracellular polymeric substances in aerobic granule morphology

This thesis examines the influence of physical properties of structural EPS on granule morphology. Two types of structural EPS are found to be important. These types of structural EPS are: surface bound EPS and hydrogel forming EPS matrix. VirtualLeaf is used to model granules which contain only binding surface bound EPS. The TST model is used...

Variation of Chemical and Structural properties of Waste Aerobic Granular Sludge (WAGS) and Flocculent Sludge in Anaerobic Digestion

A comparative batch experiment as well as a biochemical methane potential(BMP) test were conducted over 44d for aerobic granular sludge (WAGS) and waste flocculent activated sludge(WAS) on sludge anaerobic digestion (AD), to give an insight into the chemical and mechanical properties change of the EPS in different sludge source during AD process...
