Tank and Lagoon Covers for Water and Wastewater Applications

Products 

  • Structurally Supported Covers

    Geomembrane Technologies™ brand structurally supported covers consist of a high-strength, retractable sheet of coated fabric tensioned across a low-profile aluminum arched frame that spans the tank opening. This design effectively controls odor and algae while still providing easy access for inspection and maintenance. Geomembrane Technologies™ brand structurally supported covers are designed to:

    • Control odors
    • Block sunlight to control algae growth
    • Reduce chlorine loss and disinfectant by-product production
    • Prevent rainwater and debris from entering tanks

    These covers reliably capture odorous offgases, yet disconnect and retract easily. They are extremely durable, UV-protected, and resistant to vapors produced by wastewater treatment.

    Structurally Supported Covers
  • Biogas Collection Covers

    Geomembrane Technologies™ brand gas collection covers collect valuable biogas from anaerobic digestion systems. Custom-designed for tanks and lagoons of all sizes, Geomembrane Technologies™ brand covers are gastight to contain odors and protect biogas from contamination. In waste-to-energy projects, the collected methane gas can be used as a renewable fuel to generate process heat or electricity, helping to offset energy costs. Geomembrane Technologies™ brand gas collection covers are designed to:

    • Collect biogas to be converted into green energy
    • Control odors
    • Lower operating costs
    • Provide thermal insulation
    • Allow access for sampling and maintenance

    Built to withstand tough conditions, Geomembrane Technologies™ brand covers are fabricated with strong, long-lasting materials to resist tears, punctures, chemicals, an...

    Biogas Collection Covers
  • Biogas Control Systems

    Geomembrane Technologies™ brand control systems safely deliver collected biogas from our gas collection covers into a pipeline for renewable energy conversion or disposal, while monitoring and protecting the cover. The biogas control systems are designed to:

    • Safely deliver biogas to be converted into green energy
    • Protect the cover from damages
    • Control sediment and moisture in the gas
    • Withstand corrosive gases
    • Allow real-time remote monitoring
    • Alert operators of unsafe operating conditions 

    The control system regulates the withdrawal of biogas from underneath the cover. The system maintains a consistent vacuum by removing biogas at the same rate as it is generated. The cover is drawn to the water surface, helping protect it.
