Koerner's mobile weir box is used to eliminate grease and oil from the surface of pickling or other pre-treatment baths.
The weir box is suspended from the tank rim and dipped into the bath. By switching on the integrated submersible pump, the substances that have accumulated on the surface flow alongside the tank towards the weir and are held back in the mobile weir box, while the high-density pickling liquid is pumped back to the opposite front side of the tank.
The pump remains in operation until the surface of the bath is clean, which takes only a few minutes. Now, the content of the weir box is passed through a bag filter and the mobile weir box can be carried to the next tank to start process again.
