From Biogas Components
FARMATIC offers conventional digester systems, secondary digesters and combined gas/digestate storage as full equipment package. Our customers are independent project developers, engineering consultancies and biogas research institutions.
It is our business philosophy to supply our customers with a complete hands-free digester solution with a consistently high quality all over the world. Our digesters are supplied including a double membrane gas holder and FARMATIC's electrical stirrers
FARMATIC digester and biogas storage solutions are supplied in standard sizes or in custom designs according to client preferences.
By combining a digester chamber with an integrated gas holder, conventional digester systems are a cost-effective alternative for smaller digesters up to 2,400 m³ and for substrates that can easily be mixed. FARMATIC uses this tank design as post-digester and combined gas and digestate storage in larger turnkey projects.
- one insulated and corrosion-resistant digester tank made from bolted steel panels. The tank wall in touch with biogas is designed in stainless steel or special high quality glass-fused-to-steel due to the aggressive properties of the hydrogen sulphide in the gas.
