After mechanical dewatering, sludge contains 20 % dry solids. Disposal of that sludge which contains 20% dry solids is very difficult without drying process; moreover, it has negative impact on environment as well.
Solar drying system is based on the greenhouse effect where sludge is spread into a greenhouse and mixed mechanically with a mixing device periodically. Height of the sludge should be around 30 cm to reach max. Sludge in the greenhouse is mixed continuously and get dry, after that dry sludge is transferred to the out side of the green house with a conveyor system.
