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

The material to be dried is brought into the drying hall, usually by wheel loader or push-off trailer. Using free solar energy and with the help of the Electric Mole, a fully automatic turning robot, and a ventilation system, the material is uniformly dried to the desired DS content. Removal is again carried out by means of a wheel loader.
The integrated sludge drying and carbonization technology is a closed & sealed "Pyrolysis" system, under the condition of lack of oxygen, for maximum evaporation of moisture in the sludge.
