METHANE DIGESTERS
These methane digesters, or biogas digesters, are covered with a double membrane cover which is blown up with air. The shape of these biogas digesters is why some people call it balloon biogas digesters. In these balloon biogas digesters, the gas is stored at the top, the balloon part. To keep the bio digesters in shape we use three components: blowers, air supply system, air relief system. The blower blows air between the inner membrane and the outer membrane and the air supply and air relief system make sure the pressure between these membranes are regulated.
The pressure can be regulated by over- and under pressure valves. The over- and under pressure valves make sure the gas pressure in the methane digester does not exceed the pressure limit.
Commercial biogas digesters can be used for anaerobic digestion installations in for example the agricultural market or industrial wastewater treatment plants. We always make sure we deliver a complete product which is safe and of a high quality. The biogas digesters are 100% high frequency welded and obtainable up until a diameter of 35 meters. The installation is always done by our own experienced and skilled installation and service crew, who will install the digesters completely, so you
Double membrane cover
Double membrane covers can be used for anaerobic digestion installations in, for example, the agricultural market or industrial wastewater treatment plants. Double membrane covers are available up to a diameter of 35 meters. Double membrane covers give you the opportunity to store more gas in your plant(s). With double membrane covers, you are always in control of how much gas you want to take out. Double membrane covers can be very interesting as a digester cover, especially in combination with our biogas domes.
