Improved dewatering by hydrothermal conversion of sludge (2009)

Saveyn, Hans, Curvers, Daan, Schoutteten, Maarten, Krott, Ellen, Van Der Meeren, Paul

A growing demand for renewable energy resources, together with increasing criticism on the competition with food crop production caused by current production methods, has stimulated new interest for...

Influence of Experimental Parameters in On-line Determination of Floc Size Distribution (2007)

Ruxandra Govoreanu, Ra Govoreanu, Ingmar Nopens, Bob De Clercq, Hans Saveyn, ...

In order to develop an experimental technique to directly monitor the dynamics of activated sludge it is necessary to analyse some parameters that can influence the flocculation process and to find...

Electrolytic Reduction Improves Treatability of Humic Acids Containing Water Streams (2007)

Satyawali, Yamini, Wiele, Tom Van De, Saveyn, Hans, Meeren, Paul Van Der, Verstraete, Willy

BACKGROUND:An understanding of the structure of humic acids is essential for their degradation or physical removal from wastewaters. This work aims at targeting the reactivity of these molecules by...
