Anoxic/Anaerobic tanks, mixing

With a mixing solution from Landia, a quick mixing of incoming wastewater is ensured, and thereby the least possible change in the biological conditions of the tank.

Landia has a wide range of different types and sizes of mixers and can therefore tailor the optimal mixing solution to your particular system. Of course, with consideration for the lowest possible energy consumption and a complete mixing of the tank contents.

Make the best use of energy consumption


The energy consumption for mixing plays a major role in the process at a sewage treatment plant. This is something Landia has always focused on, which is completely natural for a Danish company.

Landia has a wide range of different types and sizes of mixers and can therefore tailor the optimal mixing solution to the specific task of your plant.

The durability is almost legendary


Landia supplied the first mixers for sewage treatment plants in the late 1980s. There are many Landia mixers at sewage treatment plants around the world who have passed the 25-year mark – some even 30. 

Now that’s truly sustainability!

Constant follow-up, testing and development has meant that we have kept up with the times and today can offer energy-efficient mixing combined with a lifetime beyond the usual – something we are of course willing to guarantee!

In 1989 we received 16 mixers from Landia. 14 of them are still running, and we have moved the propellers from the last two to other mixers.
