In recent years, a significant part of research on wastewater treatment has focussed on development of compact systems. Wastewater treatment plants (WWTP) can be designed compact when biomass is maintained in the system without the use of conventional settling tanks as in flocculated activated sludge systems. Examples are developments in the field of Membrane BioReactors, Biological Aerated Fil...

Aerobic granular sludge (AGS) is based on self-granulated flocs forming mobile biofilms with a gel-like consistence. Bacterial and structural dynamics from flocs to granules were followed in anaerobic-aerobic sequencing batch reactors (SBR) fed with synthetic wastewater, namely a bubble column (BC-SBR) operated under wash-out conditions for fast granulation, and two stirred-tank enrichments of ...

We investigated a method for producing granulated boehmite (BE) by using an organic binder and measured its phosphate-ion-adsorption capacity. BE was granulated using polyethylene terephthalate (PET), and its structure was characterized by scanning electron microscopy and X-ray diffraction analyses. The properties of granulated BE such as specific surface area, mean pore diameter, pore volume, ...

The construction and demolition waste generation is increasingly evolving with the rapid urbanization, more than a quarter of produced being landfilled without further treatment or recycling strategy. Hence, sustainable management valorization methods such as in materials becoming essential to tackle economic environmental burdens landfilling waste. Construction has been intensively studied. Ho...

The various interaction forces that govern the stability/flocculation of concentrated suspensions are briefly described. Combination of these interactions result in three main energy-distance curves which determine the final state of the suspension. This ranges from colloidally stable to strongly flocculated (coagulated) suspensions. A schematic representation of the various states of suspensio...

OBJECTIVE GH-producing pituitary adenomas display two distinct morphological patterns of cytoplasmic GH-containing secretory granules, namely the densely and sparsely granulated somatotroph adenoma subtype. It is unknown whether these morphological variants reflect distinct pathophysiological entities at the molecular level. METHODS In 28 GH-producing adenoma tissues from a consecutive set of...
