Abstract The object of this invention is to provide a sludge dehydration and dry system. This system feeds sludge-laden waste liquid from a sludge inlet unit (10) to pressure vessels of an automatic pneumatic pump (20), and feeds waste liquid to a dehydration unit (30) by pressurizing the surface of waste liquid within the vessels using compressed air, thus dehydrating the sludge to form sludge cakes, and dries the sludge cakes at the filter plates (33) of the unit (30) using compressed air from a dry unit (18). The moisture content of the sludge cakes within the dehydration unit is reduced by inflating the membranes (90) with compressed air. After the sludge compression and dehydration process, the filter plates are separated from each other by a separation unit (34), and so the resulting sludge cakes are dropped from the filter plates onto a feeding conveyor (37) to be discharged from the system.
