Our digester covers hold biogas under pressure to help in the anaerobic digestion process of wastewater sludge. The Vertical Guided Gas Holders travel through vertical guides recessed on the rim skirt. The floating digester cover height varies according to the amount of biogas being stored.
Vertical guided, floating digester covers provide flexible biogas capacity, odor control, scum submergence, minimum volume of supernatant and freedom from explosion and uplift damage
These digester covers are suitable for applications where unbalancing loads, winds, snow, etc. are not probable. Generally, these are for digesters under 40 feet in diameter or with a short skirt length.
