SPEL Electrocoagulation

[tribulant_slideshow gallery_id="12"]

SPEL electrocoagulation is the distinct economic and environmental choice for meeting water treatment discharge standards and compliance requirements. Capital and operating costs are greatly improved in comparison to traditional technologies with distinct process advantages.

The SPEL electrocoagulation process destabilises suspended, emulsified and dissolved contaminants in an aqueous medium by introducing an electrical current into the medium. The electrical current provides the electromotive force to drive the chemical reactions. When reactions are driven or forced, the elements or compounds will approach the most stable state. As this occurs, the contaminants form hydrophobic entities precipitate and can easily be removed by a number of secondary separation techniques.


The SPEL EDA TT process destabilises suspended, emulsified and dissolved contaminants in an aqueous medium.

The process has been proven effective for a wide range of contaminants:

  • Removes heavy metals such as oxides that pass TCLP (Toxic Classification Leaching Procedure)
  • Removes suspended and colloidal solids
  • Removal of dissolved solids
  • Breaks oil emulsions in water
  • Removes fats, oil and grease
  • Removes complex organics
  • Destroys and removes bacteria and viruses
  • Processes multiple contaminants
