Drilling and sawing slurry
Disposing of drilling and sawing slurry directly into rivers, lakes or the sewerage system
without suitable pretreatment is problematic from an environmental point of view.
▶
Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶
Collect the drilling or sawing slurry (for example, using a wet-type vacuum cleaner).
▶
Allow the drilling or sawing slurry to stand for some time or add a flocculation agent
to help the fine particles in the slurry settle and separate from the water.
