Biogas Capture & Floating Cover

Floating cover is a lining system that can be floated on the liquid. Properly designed floating cover systems prevent fluid loss due to evaporation, reduce chemical demand and improve water quality by preventing contamination from bird droppings, airborne particulates, dead animal’s pollen and other pollutants.

Floating covers block off sunlight preventing algae bloom. In anaerobic digester systems, floating covers are increasingly being used to capture organic gases and to reduce biological oxygen demand (BOD). In farming applications they have been successfully used with enzymes to capture methane gas that is used to fuel electricity producing generators.
