Recommended pretreatment for disposal of drilling slurry

The disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable
pretreatment presents problems of an environmental nature. Ask the local public authorities for
information about current regulations.
1. Collect the drilling slurry (e.g. using a wet-type industrial vacuum extractor).
2. Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site
(adding a flocculant can accelerate the settling process).
3. Neutralize the left-over water (alkaline, pH > 7) by adding acidic neutralizing agent or diluting it with a
large quantity of water before it is allowed to flow into the sewerage system.
