Applications of the EKS-DT Process

The EKS-DT process is flexible, reliable, highly cost effective and practical to deploy.

Some of the uses in the oil sands include:

  • Volumetric dewatering of legacy tailings deposits,
  • Periodic dewatering of new fresh tailings,
  • Accelerated dewatering of partially dewatered tailings (e.g. following flocculation and/or centrifuge)
  • Consolidation of the bottom of end-pit lake,
  • Strengthening off-spec soft spots in partially dewatered tailings deposits,
  • Preventing water migration/ seepage (e.g. berm walls), and
  • Dewatering of froth tailings.

The EKS-DT process is capable of dewatering other forms of mine tailings, drilling mud, dredging spoils, industrial and municipal sludges.  An advantage of the technology is that the water that the process releases is clear due to the action of electrophoresis.  The quality of this water is suitable for reuse in most cases.

EKS-DT is:

  • Mobile and modular in design. This allows it to operate in extreme weather conditions, year round, and in almost any environment.
  • Adaptable. The program is easily configured to meet specific producer needs and complement existing tailings treatment plans.

EKS-DT has many uses:

  • In-situ at tailings process receiving ponds
  • In pit or legacy holding lakes
  • Engineered treatment cells
  • Winter final drying treatment
  • Fluid fine tailings can be reduced to pumpable paste, an impermeable brick, or anywhere in between, depending on the reclamation site needs.
  • Vertical in-situ treatment inside a settling basin earthen (sand) dam walls to:
    —Harden MFT deposits into a plaster like substance; and—Stabilize lake wall foot and bottom areas to reduce permeability, and improve long-term impoundment security of fine solids containment.
