Water in sludge appears to be of four kinds; free water which freezes at normal freezing temperatures; interstitial water, which freezes at lower temperature due to high dissolved solids concentrations; vicinal water which is associated with solid su

We postulate a mechanism for floc formation and demonstrate its feasibility by building synthetic sludge flocs. In this work, polystyrene latex particles of a size similar to bacteria are used to simulate individual bacteria; alginate, a polysacchari

The effect of freeze-thaw conditioning for enhanced sludge dewatering is effective only when sludge freezes completely and slowly. This recognition has inhibited the development of commercialized freeze-thaw conditioners. If sludge is frozen in thin

The pyrolytic and combustive reactions of thermally decomposing pelletized refuse-derived fuel in air and nitrogren atmospheres is studied through the experimental determination of the temperature profile within cellulose cylinders. The internal temp

The time needed to naturally thaw sludge in a freezing bed depends on the thermal conductivity of the settled sludge layer deposited on the thawing sludge. The objective of this research is to measure the thermal conductivity of this layer. Six diffe
