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.

Using efficient recycling technology, the solids absorbed by the drilling fluid during drilling are separated out almost entirely. This allows the cleaned fluid to be reused continuously in a closed-loop system. This speeds up drilling progress and reduces the consumption of water and Bentonite. In this way, recycling sustainably improves the cost-effectiveness of HDD drilling.

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.
