Sludge treament 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

Sludge Drying  Enox

Sludge Drying Enox

Solar sludge dryers use sunlight energy for drying solar drying of sludge differs from other sludge drying technologies primarily by the process temperature in disc drum or fluidized dryers water evaporation occurs at temperatures above 100 c in solar dryers the process is carried out at lower temperatures using the greenhouse effect lowwavelength
