High-efficiency solids removal, fluid preservation for the entire circulating volume

M-I SWACO mud cleaners use a two-stage separation process for enhanced drilling fluid recovery. This design enables our mud cleaners to handle the entire circulating volume and remove and dry solids, while retaining premium base fluid vital to drilling success.

Single unit for two-stage processing

Our two-stage process is achieved by a combination of hydrocyclones mounted over a shale shaker to operate as a single unit. The hydrocyclones make the primary separation with underflow directed onto the shaker vibrating screen.

Effective for weighted, unweighted fluids

M-I SWACO mud cleaners are equally effective for both weighted and unweighted drilling fluids and effectively lower both drilling fluid expenses and disposal costs.
