Abstract
The dewatering of sludges from the treatment of potable water is complex and sludge behaviour in dewatering shows a strong dependence of the coagulant and/or flocculant type and amount used to remove both particulate and natural organic matter from solution. The characterisation of the dewaterability of these sludges is not easy but if performed comprehensively, allows quantitative comparison of the expected dewatering behaviour. The methodologies to characterise dewatering in a comprehensive manner and the subsequent outcomes of dewatering device modelling using this approach has been outlined. © 2006 Elsevier Ltd.
