Drilling slurry
Disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment
presents environmental problems.
▶
Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶
Collect the drilling slurry (for example, using a wet-type vacuum cleaner).
▶
Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site
(addition of a flocculent may accelerate the settling process).
▶
The remaining water (alkaline, pH value greater than 7) must be neutralized by the addition of an acidic
neutralizing agent or diluted with a large volume of water before it is allowed to flow into the sewerage
system.
Drilling dust
▶
Dispose of the drilling dust collected by the vacuum cleaner in accordance with the applicable national
regulations.
12 Manufacturer’s warranty
