Aeration tanks, mixing

Get the optimal use of energy consumption in your sewage treatment plant with efficient mixing of aeration tanks.

Best oxygen transfer

With a mixer from Landia, aeration tanks are mixed by creating a horizontal flow in the wastewater. The water is moved around the tank at a predetermined velocity. This ensures the best oxygen transfer and prevents the sludge from settling.
In this process, a large part of the total energy consumption is taken up, so at Landia our focus is on optimizing this.

Energy-efficient mixing

Landia supplied the first mixers for aeration tanks in the late 1980s. 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 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.
