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.

Abstract:
The present invention relates to the field of membrane gas holders, or gasometers, particularly of the type that can be used to store biogas (organic gas) generated through the digestion of sludge, slurry and organic substances in general, or for storing gas emitted from slurry storage tanks containing fermentable matter. More in detail, the invention relates to an elastically stabilized gasometric dome (1) for a tank (2) containing liquid (3), adapted to delimit, between the surface of said liquid (3), the walls (2') of the tank and the dome, a variable volume storage chamber (4) for gas, wherein said gasometric dome (1) comprises: - a gas impermeable flexible membrane (5); - continuous fastening means (6) of an edge (5') of said membrane (5) to a rim (2") of said tank (2). Said membrane (5) is made of an inextensible material, having an extension of the surface thereof greater than that of the surface delimited by the rim (2") of said tank (2), and said gasometric dome (1) comprises a plurality of linear elastic elements (7) arranged orthogonally with respect to the rim (2") of said tank (2), adapted to cooperate with said membrane (5) to allow elastic expansion and contraction of said gasometric dome (1) and ensure the stability thereof.
Abstract:
A floating cover for tanks (100) for storing liquids, comprising: - a plurality of floating edge elements (1); - a gas-proof sheet (3), supported by said floating elements (1), which extends beyond them by means of a skirt (5);
wherein said floating cover comprises cables (2) arranged radially, which connect said floating elements (1) to one another, and said skirt (5) is fixed to the bottom of said floating elements so as to constitute, together with the liquid contained in the tank (100), a perimetral hydraulic guard, arranged for keeping gases and volatile substances underneath the sheet (3).
