The studies aimed at examining the influences of the particle size distribution and surface charge on the behaviour of sludge in dewatering. It was possible to show that defined size dispersions of sludge particles as well as surface charge are necessary to reach better dewatering results and that the found correlations were independent of the type of sludge and the sewage treatment plant (Friedrich et al., 1990 and 1991). Based on laser diffraction measurements to determine panicle size distribution it was found that it was necessary to set a specific proportion between fine and large sludge particles in order to produce the best possible dewatering results and to get the required shear resistant flocs. To characterize the surface charge of the sludge particles various measuring methods were used. Determining the zeta-potential is a suitable means to describe the kinetics of degradation process in the sludge.

ABSTRACT The pursuit for waste recovery has been the best way to contribute to environmental sustainability. The mix of sewage sludge (SS) from Sewage Treatment Plant with diatomaceous material containing oil (DE), used as a filter in biofuel production, can form a substrate rich in minerals and organic matter through vermicomposting. Therefore, this study aimed to produce vermicompost using worms, Eisenia foetida, from a pre-compost (PC) of sewage sludge and garden pruning residues mixed with different proportions of DE in relation to PC: 0; 7.53; 15.06; 22.59; and 30.12% v/v. The design was randomized complete blocks with five treatment replicates. The chemical characteristics of the vermicompost were analyzed after a period of four months. The proportion of up to 30.12% v/v of DE met the criteria established for agriculture uses, registration and marketing of the product as organic compost in accordance with the Normative Instructions SDA 27/2006 and 25/2009 from the Ministry of Agriculture.
