L'influence de la granulometrie des boues residuaires urbaines sur leur deshydratation. the influence of granulometric characteristics of urban waste sludges on their dewatering process.

摘要

The evaluation of particule size distribution of waste sludges, conditioned or not, is easy to realize even with a minimum of laboratory equipment. Close relationships exist between this distribution and the ability of sludges for filtration and dewate#x2010;ring. Even if particule size distribution is probably a consequence of complex interactions between many physico#x2010;chemical and physical parameters, we might expect that the measure of this distribution can be used to improve the filtration efficiency of sludges.
