Sludge Drying
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. Low-wavelength
