The invention, subject of the present application, concerns the technical field related to the dewatering of the mud deriving from the purification of the waste waters, civil and industrial and from the various chemical/pharmaceutical and minerals processes. The current invention is a filter press where the mud dewatering by means of pressing, occurs contrasting the thrust of the hydraulic pump which introduces the muddy mixture between the plates on the press, with a thrust obtained blowing with a liquid fluid or gassy in pressure, one or more elastic coverings inserted in the press, which replace the oil-pressurized piston. |
