Presentation
The BioMix-S is a slow-speed submersible mixer, specially designed by BIOTRADE to homogenise sludge in closed silos with volumes greater than 300 m³.
Unlike conventional systems, it rests at the bottom of the silo and remains stable under its own weight, ensuring optimal stability.
Its 304L stainless steel propeller and low-speed motor, with an output speed of 100 rpm, create a gentle but powerful upward flow, ensuring complete sludge homogenisation without the risk of sedimentation.
