Energy Crop silage + manure
External module required, often manual control.
Mixers are installed close to wall, risk for overheating of the mixer motor due to lack of flow circulation around the mixer and sediments risk on HE pipe and tank center.
mixing efficiency 14 W/m3 tank active volume
Risk for crust formation (scum), Need to empty the tank to remove defected mixers
Pro-Biogas Technology
HRT 20-28 day,
Temperature 42ËšC
CH4 60-65%
​allows dosing variety of organic wastes and substrates in different quantities thanks to Hydrolysis as separate phase
​pH < 4,5, higher temp.
​Just one mixer installed in the central pipe, to breaking down the crust formation, prevent foaming on the surface and bottom sediments
13,46 W/m3 tank working volume mixing efficiency
Easy mixer installation and replacement
Flexible design according to customer demand,
Possibility to add module
Pro-Biogas Value Proposition
~ 18% more Biogas Yield
​More flexible to tack different feedstock
Coli, Salmonella disinfection thank to the higher process temperature/lower pH in Hydrolisys step
Fewer devices in whole plant, less wear, excellent engine cooling
38% better power consumption
Easy maintenance and replacment
easy scalability
shortened installation process
ROI for 4161 MWh/y
Scientific Support
12–18 months.
Typical return in 8–10 years.
