In fact, the draining solar drying is considered as an innovative solution in the area of sanitation. By coupling the solar drying with the filtration on a drying bed, this solution consists in increasing the flow of water extracted from the sludge by accelerating the evaporation under the greenhouse effect surrounding the drying bed.
The draining process Once the solar controller turns off the pump (s) or in case of power failure, the draining process occurs automatically. It has a protective function for the DBS, and implies the draining of the HTF from the upper part of the hydraulics into the drainback volume.
It consists in coupling the solar drying with the filtration on a drying bed. Then, the flow of water extracted from the sludge increases by accelerating the evaporation under the greenhouse effect surrounding the drying bed. This is an innovative solution in the field of sanitation.
Since drying is an important step in sewage sludge treatment, we present, in this paper, a comparative study to the performances of the drying bed and the draining greenhouse under natural and forced convection in summer and winter. This is significant because we investigate the characteristics of two solar drying techniques.
By coupling the solar drying with the filtration on a drying bed, this solution consists in increasing the flow of water extracted from the sludge by accelerating the evaporation under the greenhouse effect surrounding the drying bed. However, the drying bed is one of the most used methods in Tunisia.
It has about 2860 to 3200 h of sunshine per year and receives average solar energy of 4.8 kWh/m 2 d [ 2 ]. The drying bed is one of the solar drying techniques. However, this method can be suitable for sludge drying only in locations where the solar radiation is available throughout the year.
