Nenufar Cover - BIOGAS TANK COVER Alerta

The Nenufar cover provides three main advantages for farmers. First, the device limits the emissions of greenhouse gases (methane and NO2) and therefore odors coming from manure storage tank. Then, the cover catches rainwater, increasing the storage volume and limiting spreading costs. Eventually it stimulates anaerobic digestion process in the storage tank, captures and stores the biogas in order to use it directly on boilers or radiant.
The Nenufar patented device is a floating membrane, tailor made to adapt on any size of manure tanks all year long. The system prevents the biogas to get in contact with the concrete tanks and in this sense avoids corrosion issues.
