If the tank is filled with already fermented substrate coming from other Biogas containers,
there could be material floating on the surface, due to a high dry matter content. That could
also occur in case of a fault in the Biogas plant and the consequent unforeseen mixer
stopping.
In case a great quantity of floating wastes is present, before starting the mixer, take
the necessary steps, which of course have to be previously agreed with the dealer or
the manufacturer of the machine.
Attention! The mixer drive line can be damaged by extreme side thrust caused by
excess floating materials.
The propeller vane can undergo excessive stress which could affect negatively the tank
stability.
