The “Ca’ Foscari University of Venice”, a European excellence study review of anaerobic digestion systems carried out a technical comparison between gas injection and mechanical mixing systems.
Comparison between the two technologies clearly shows advantages of gas injection mixing systems.
They can be summarized as follows:
. no sedimentation due to the mixing by gas bubbling from the bottom
. high production of gas due to complete and uniform mixing and to a low temperature gradient in the sludge
. low power consumption (up to 50% energy saving): no friction between sludge and mechanical parts
. high reliability: no corrosion and no struvite
. easy and low cost maintenance: no parts in movement inside the sludge
