Blower units for WWTP Krnov (CZ)
In September 2021, two new KUBÍČEK blower units type 3D80B-250K (132 kW) were delivered to the Krnov WWTP. The delivery included dismantling and purchase of obsolete...
Once upon a time, there was a small cottage. It stood on top of “Praděd” (Great-grandfather) the highest mountain in the Jeseníky Mountains. But it wasn’t just an ordinary cottage. It was a wastewater treatment plant.
This is also the way how to start this story.
The inconspicuous facility of the biological wastewater treatment plant, which is almost inaccessible from autumn to spring and often covered with snow high above the roof, is located on the northeastern leeward side of the mountain, just a few meters from the transmitter. Nevertheless, the average visitor to the top of the Jeseníky Mountains will hardly notice it.
Since 2010, the blower unit 3D19A-032K, which we have regularly serviced, has served continuously for eleven years. At the end of 2021, we installed a new KUBÍČEK blower unit of the latest generation. Type 3D19A-050N (2.2 kW) with accessories made of powder paint, and with a stainless steel noise protection cover.
When designing the unit in similar cases, it is necessary to take into account the high altitude (1491 m.a.s.l.) and extreme climatic conditions at the installation site. This affects the design of the amount of intake air as well as the designed size of the electric motor and its cooling.
