Submersible mixers successfully complete eight years of untroubled operation at one of the largest waste water treatment plants in Germany.
Submersible mixers made by Landia have completed eight years of untroubled operation at one of the largest waste water treatment plants in Germany At the Bremen-Seehausen plant, Landia's mixers have been working nonstop, 24-hours per day, seven days per week for a full eight years

Cutter pump goes the distance
A new high-pressure cutter pump for long distance pumping of heavily contaminated liquids has been developed by Landia.
Cutter pump refuses to clog
Thanks to Landia's novel external knife system, the MPTK cutter pump is becoming an increasingly popular choice for tough applications because it refuses to clog up.
One of the benefits that the 26 submersible Landia Pop-I mixers bring to the plant is the highly efficient mixing of waste water with activated sludge, which has to meet stringent environmental requirements laid down by German law.
"The mixers have operated satisfactorily through the years and so far we have had no problems", said Sven Wedderman, Head of Process Technology at the plant.
"The utility value of the biological process and the quality of the treated waste water at Bremen-Seehausen depend very much on the reliability of the Landia mixers, which apart from routine servicing, have proved virtually trouble-free".
The mixers continue to ensure that all bacteria and organic matters are equally suspended throughout the whole tank volume, creating optimum homogenised waste water for a biological process that has a cleaning performance of 91% for COD, 92% for phosphorous and 79% for nitrogen.
The slow-speed Pop-I 1.5kW, 150rev/min flow makers are also energy efficient, designed to provide a gentle treatment of the medium with thorough, efficient mixing, achieved by a low number of propeller revolutions.
This improves flocculation and ensures the biological balance.
The low number of revolutions also creates less turbulence on the surface and thus prevents oxidation in the anoxic tank.
