Depending on the soil conditions and drilling parameters, large amounts of drilling fluid may be required. The costs of water consumption, Bentonite and additives such as polymers are correspondingly high. Hence, it is worthwhile to recycle the used HDD drilling fluid for multiple use.

With an efficient recycling technology, the solids that are absorbed by the drilling fluid during drilling are almost completely separated again. This means that the cleaned mud can be continuously reused in a closed mud circuit. This accelerates the drilling progress, significantly reduces wear on drilling tools and pumps and lowers the consumption of water and bentonite. This way, the multiple use of the drilling fluid and the separation of the solids through recycling sustainably increase the economic efficiency of an HDD bore.

As a general rule, the more efficient the recycling plant, the lower the costs for resources and disposal. Only a high-quality and technically mature recycling technology guarantees maximum separation of the cuttings from the drilling fluid so that it can be reused with no worries. TRACTO's MRU250HE recycling unit has been developed and designed with these aspects in mind.
