Abstract: A process for dewatering petroleum-containing sludges by a two-stage method using finely divided additives and organic flocculants, wherein a) finely divided additives, such as ash, coal, sand or mixtures of these, in a free-flowing form or as an aqueous suspension, are homogeneously dispersed in the petroleum-containing sludge, in an amount such that the total solids content of the resulting mixture is from 10 to 30% by weight, especially from 12 to 20% by weight, b) this sludge mixture is treated with an aqueous solution of an organic flocculant, preferably of anionic nature, c) the greater part of the sludge water is removed by gravity filtration, d) the pre-dewatered sludge mixture is treated with an aqueous solution of aluminum salts or trivalent iron salts and e) this mixture is substantially dewatered by pressure filtration, in the course of which the greater part of the petroleum present is also removed. 26
