BioMIX Submersible Mixer homogenises the overall bulk of liquid and solid within the pond. This avoids the formation of islands of sludge, particularly at the low-flow areas such as perpendicular corners of ponds.

BioMIX also crucially prevents the short-circuiting flow pattern within a pond that naturally occurs in all sludge ponds. This way, the optimal retention time (HRT) of the lagoon is maintained.
