Pit Dry ™ HDD is an inert polymer that is mixed with bentonite slurries using a PD-300 Machine. This simple, one-step process changes the spent liquid drilling fluid into a solid that will pass landfill paint filter and slump tests. This allows the bentonite spoils to be trucked as solids to landfills or mixed into the soil at project sites.
- Environmentally safe, does not alter mud chemistry
- Works in a wide pH and solids range
- Reduces volume and weight over time
- Lowers disposal costs
- Available in 40 lb. bags
