Investigations of re-hydration increase of dried sludge
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2013, Vol 45, Issue 2
Abstract
The paper presents the results of investigations of re-hydration increase of a sludge which had been dried to ca. 87% of dry mass and stored in an airy place under roof during 2.5 years. As well, trials were carried out for a completely dried sludge (0% of water), stored outside under roof as well as inside in a laboratory room. To determine a maximum level of humidity increase, the results of re-hydration increase were presented for a sludge stored in conditions of capillary ascent. Additionally, a density, porosity and bulk density were determined for the investigated sludge.
