Mud Reclaiming/Recycling System Application and Effect

Mud reclaiming recycling mixing system is designed for mud recycling of trenchless. Such as tunneling shield, HDD, and pilings. It can help reduce costs and improve construction efficiency significantly.

Drilling fluid is circulated directly from the drill collar to the AIPU Mini Shale shaker for first phase solids removal. And a positive displacement feeding pump takes the drilling fluids under the shaker tank to feed AIPU mini decanter centrifuge for fine solids removal. The Cleaned drilling fluids are then returned to the drill hole for reuse. The highly mobile unit also incorporates a mixing chamber and mixing hopper and pumps, which enables drilling fluids chemical to be added accurately and efficiently. The APLW223 baby centrifuge is the world's smallest decanter centrifuge for drilling fluids treatment. It’s popular in the diamond core drilling industry.  Mud Reclaiming/Recycling System provides a highly innovative alternative to traditional drilling sumps. The closed-loop fluid system significantly reduces the environmental impact and greatly improves the efficiency of drilling operations.

Rise of mud recycling
Rising costs of mud disposal and the limited availability of disposal sites are driving some HDD contractors to reuse their drilling fluid, which requires a reclaimer.

“Environmental concerns are also a factor so we are seeing more reclaimers required in drilling specs,” says Heinen. “Also mud disposal is cost-prohibitive and we are seeing an increase in mud recycling requirements on job sites.”

Cost factors in mud disposal include hauling of used fluid, whether it is trucking or rail cars, sometimes out of state. Dumping costs are expensive; certain situations may require additional additives to be mixed with the used fluid that has come into contact with hazardous materials underground.

It is estimated that about 20 percent of what comes out of the exit pit is solids and cuttings. Mud recycling is simply using a reclaimer instead of a standard mixing system — it’s a combination of a mixing system and a system to clean dirty fluid, and then recirculate the cleaning fluid.

A standard mixing system employs a mixing hopper, an agitation system, and a pump to deliver to the drill. These components are standard no matter the size and capacity of the system. The hopper is where bentonite is introduced into the clean water or clean mud. The agitation system continuously circulates the fluid to keep the components in the suspension, and the pump creates the flow to deliver the fluid into the drill.

A reclaimer is generally used on drill projects when you are using a large volume of fluid. Smaller projects can utilize an excavation system and dispose of mud in a cost-effective manner. A reclaimer utilizes a series of shakers, cones, and screens to filter out solids from the fluid, leaving the bentonite and other additives in the solution and recirculating the cleaning fluid.

The reclaimer is generally configured with multiple tanks which can include a clean mud tank, a dirty fluid tank, and a desander and/or desilter tank. Dirty fluid is drawn from the return pit and pumped across the first cut shaker(s), which sift out all the larger particles of sand and debris. Then the fluid is pumped through the desander cones where a cyclonic motion is used to eliminate even smaller particles, and again across a shaker screen equipped with a finer mesh screen to further the cleaning process. The fluid finally passes through desilter cones and again across a final set of shakers and screens, which separate out the smallest micron particles from the drilling fluid completing the cleaning process. Each deck on the reclaimer uses progressively smaller screens to remove micron-sized elements from the fluid. Once through, the fluid is stored in the clean mud tank ready to be recirculated back down hole.

“You won’t get 100 percent return on your fluid due to several scenarios,” says Heinen. “There is typically some circulation loss either due to soil absorption, formation instability or the drilling process. When using a reclaimer, you should use a mud test kit to test the clean fluid being held in the clean mud tank. This test will verify both information on the cleanliness of the mud and be an indicator of how well your cleaning system is performing.”
