Biogastechnik Süd GmbH products

We have developed the Sepogant Compact screw press separator as an alternative to our stationary Sepogant screw press separator. With a few simple actions, the compact separator is ready for operation in no time at all. After use, it is just as easy to make the unit ready for transport again.

The Vapogant digestate evaporator treats the digestate of the biogas plant to produce a usable, concentrated fertiliser with reduced water content. We remove most of the water from the digestate through vacuum evaporation using waste heat from the CHPS. At the same time, volatile nitrogen is bound so that any emissions during spreading will be minimised, making the nitrogen available as ammonium sulphate solution (ASS). The goal is to use the available waste heat to thicken or enhance 100 % of the digestate produced in the biogas plant. This is achieved with a very high evaporation rate of 2.5 litres per kilowatt of thermal output. At 500 kW plant capacity, this is equivalent to a volume reduction of about 10,000 m³ per year. The plant is available in a module size of 400 kW or 500 kW.

The Varibull paddle agitator is a tried-and-tested, highly reliable agitator for digesters, post-digesters and digestate storage tanks. The low-maintenance drive unit is installed on the outside at the pit and is therefore accessible at all times. A maintenance-free mechanical seal provides durable sealing of the wall penetration of the drive shaft. The agitator shaft inside the pit is equipped with a maintenance-free and durable plain bearing.
