The system dries pasty or powdery products such as sludge from wastewater purifying stations, the drying occurring in a chamber receiving the products to be dried. The system includes a greenhouse with translucent or transparent walls erected on a slab upon which a bed of products to be dried is deposited. At least one wind generator is provided for generating energy which is converted to heat that is delivered to the slab upon which the bed of products to be dried is spread.

Installation for drying waste, in particular wastewater purifying sludge

Apparatus for dehydrating sludge originating from water purification stations, comprising a draining grid part positioned above a pressing-belt filter part, and a device for washing the grid wherein the device is positioned above the grid, so as to limit the drop height of the flocculated sludge between the grid and the belt, thus avoiding deflocculation of the sludge between the thickening stage and the dehydration stage, the washing of the grid being performed concurrently with the movement of the sludge on the grid.
