Description

Custom-designed for tanks and lagoons of all sizes, Evoqua’s Geomembrane Technologies™ covers collect methane gas from wastewater treatment. The covers are gastight to contain odor and protect biogas from contamination. Insulated and non-insulated versions are available.

In waste-to-energy projects, the collected biogas can be used as a renewable fuel to generate process heat or electricity, helping offset energy costs. The covers are safe to walk on, allowing operators to sample tank or lagoon contents and perform maintenance.

For safe biogas handling, the gas collection cover is best operated by a Evoqua’s Geomembrane Technologies™​ brand biogas control system, which regulates biogas flow from under the cover.
