Abstract: Disclosed is a pressostatic odor control cover for slurry treatment tank with a device for reducing the inner volume occupied by harmful and malodorous gases emitted from the surface of the slurry. The treatment tank is delimited by a base and by lateral containment walls. The cover includes: a gas impermeable flexible membrane; a gas-tight continuous fixing unit of a margin of the membrane to the tank; an insufflation unit of air inside the cover; and a discharge valve of the air out of the cover. The odor control cover also includes a diaphragm permeable to liquids and to gases, arranged to delimit a reduced volume of the odor control cover available to the harmful gases and to the malodorous substances released from the slurry. The air insufflation unit is connected to the cover above the diaphragm. The discharge valve is connected to the cover below the diaphragm.
