Sludge drying Lenntech

Sludge drying Lenntech

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.
