Gas Collection Covers
Collect valuable biogas from anaerobic digestion systems with a GTI gas collection cover.
Custom-designed for tanks and lagoons of all sizes, GTI’s innovative, patented* covers collect methane gas from wastewater treatment. The covers are gastight to contain odor and protect biogas from contamination. In waste-to-energy projects, the collected biogas can be used as a renewable fuel to generate process heat or electricity, helping to offset energy costs.
GTI’s gas collection covers are designed to:
- Collect biogas to be converted into green energy
- Control odors
- Provide thermal insulation
- Lower operating costs
- Allow access for sampling and maintenance
Built to withstand tough conditions, GTI’s covers are fabricated using strong, long-lasting materials to resist tears, punctures, chemicals, and UV rays. The covers are designed to operate in any climate and offer built-in systems for drainage of rainwater and snowmelt. Insulated versions provide additional buoyancy and help maintain consistent temperatures throughout the anaerobic digestion process. Installation and maintenance can be done without disrupting plant operation.
The covers are safe to walk on, allowing operators to sample tank or lagoon contents and perform maintenance. Hatches and ports can be provided for simple access to mixers and other equipment.
For safe biogas handling, the gas collection cover is best operated by a GTI biogas control system, which regulates biogas flow from under the cover. Advanced controls can be incorporated for biogas storage to optimize utilization in engines or boilers.
