The repeated use of the mud during the excavation process is to simply separate the excavated mud and gravel from the mud base fluid, but not all the solid phase materials are separated. The mud recovery system only separates the drilling fluid. The useless solids in the mud.

HDD Mud Recycling System is made up of drilling rig mouth to return to mud of the ground through the mud into the mud pit, using liquid slurry pump or vertical sand pump the submersible supply to shale shaker,and then male the shale shaker removing out of solid phased particles, the processed mud fall into the mud tank having many separate space. Horizontal sand pump,making 1 # bulkhead mud supply to desander, and the mud through cyclone desander get rid of t 47-75 um solid particles. The processed mud fell into the mud tank bulkhead again, another horizontal sand pump, taking out mud and supply to desilter. Mud again through desilter processing, taking out more than 15 um of solid particles. The processed mud fell into the mud tank bulkhead, this time mud was already basic can be ready for using. If the mud weight is very high, also can using the centrifuge. But the centrifuge is not used generally in the HDD.
