25 years of mixing in MBBR processes


The MBBR process consists of a carrier media, e.g. biofilm or biomedia, which are small plastic elements on which the biofilm can grow. The carrier media must be in contact with the wastewater, so mixing is necessary.

Landia has 25 years of experience with mixing in MBBR processes and has a wealth of experience. It is important that the carrier media is mixed as efficiently and gently as possible. Gentle means that the impact from the mixer is as small as possible, as harsh treatment can cause damage to the plastic elements.

No wear on the carrier media – no wear on the propeller


The contact between the carrier media and the propeller creates friction and so potential wear. Landia BioMover mixers for MBBR all have a low propeller tip speed of between 3 and 8 m/s, and they so they provide optimal protection of the plastic elements.

All Landia propellers are made of stainless steel with a material thickness of 6-8 mm. They have proven to be virtually impossible to wear out in MBBR applications – unlike certain other types of propeller material.

In fact, it is possible to set criteria for service and set requirements for information on expected lifetime costs when preparing tender material. I would like to encourage my colleagues to remember this to avoid nasty surprises in the long run.
