Patent number: 11866251Abstract: A sealing system for a covered tank, particularly a fixed gas-sealing tank in a wastewater treatment system, includes a thrust ring positioned just inside the tank rim, secured to a series of radial beams for the cover. Preferably supported on corbels anchored to the interior tank wall, the thrust ring has an outwardly extending generally horizontal flange that overlies the edge of the tank rim. To this flange and to the top of the tank rim is secured a flexible membrane seal, around the periphery of the tank. The membrane seal is easily installed, reliable as a seal, and can be efficiently replaced when needed.Type: GrantFiled: April 29, 2022Date of Patent: January 9, 2024Assignee: Ovivo Inc.Inventors: Artak Daviti Mirzoyan, Haydon Christiansen, Eric Hunter
