Drying of sludge

Sludge drying. A further reduction of the sludge weight is possible with the help of sludge drying, by evaporating the remaining bound water in the sludge. However a significant reduction of the sludge volume cannot be reached with that method. Sludge drying procedures are based particularly on contact-, convection or radiation procedures

Although the use of drying beds might be expected in small plants and in warmer, sunny regions, they are also used in several large facilities and in northern climates. In the United States, a majority of wastewater

    Drying of sludge is the process of its volume reduction that allows reducing the moisture content to as little as 5 to 10%. It is a powerful measure to reduce the disposal costs of the sludge where other management routes are limited – sludge transportation distances are long and costly (sludge is heavy)

    Sludge drying properties. Sludges of different origins and characteristics exhibit different behaviours when drying. These are most readily observed by correlating the mass water flux – the mass of water evaporated per unit surface area of solids per unit time (kg m-2 s-1) – against the moisture content of the sludge.This correlation normally reveals the three different drying phases:
