REVOC Floating Tank Covers
A floating tank cover can help to control odors, reduce evaporation, and prevent dilution of the tank contents.
Floating tank covers are used on open topped tanks where a structural cover would be too expensive. Floating tank covers are made with flexible cover materials made to stand up to sunlight and the chemicals found in tanks. REVOC® Tensioned Covers are ideal for tank covers. Tensioned cables take up the slack in the cover as the liquid level changes. A fold around the outside perimeter of the cover is created by the tensioned cables which allows the cover to move up and down. The REVOC® Defined Sump Cover uses floats and weights to create folds where rainwater can be collected. Dome type tank covers are a growing use for rubber cover materials in digester tanks. In this design a rubber membrane is placed on a structural deck and the cover attached to the perimeter. The membrane then inflates under the pressure of biogas that is generated in the tank.
