Abstract: A clip for securing one or more cover panels within a containment structure includes an annular portion partially-enclosing an internal space and two compressible legs adjoining opposite ends of the central portion. The clip further includes a clasp with first and second securing tabs configured to fixedly secure an object within the internal space and apply an outward force on the compressible legs.
Abstract: In accordance with one implementation, a floating cover system includes a plurality of cover-tethering mounts mounted along the periphery of a holding tank. Each of the cover-tethering mounts includes a guide portion insertable through a cover-holding element that is attached along a periphery of a holding tank cover. When secured to the plurality of cover-tethering mounts, the holding tank cover can rise and fall within the holding tank responsive to volumetric changes in the liquid and/or gas contained in the holding tank.
Abstract: A holding tank cover includes a gas permeable insulating membrane and a gas impermeable cover layer sized to overlay and conceal the gas permeable membrane. Together, the gas permeable membrane and the gas impermeable cover layer facilitate a controlled transmission of gas between an interior of the holding tank and an environment external to the holding tank.
