Arsenic Removal in Produced and Industrial Waters Using EPT EOX

Canada

Ground Effects successfully treated a variety of waste streams including process water, produced water and mine water to below criteria allowing the water to be available for reuse or discharge.

The Situation

Arsenic is a metalloid - a natural element that is not actually a metal, but which has some of the properties of a metal. It is a natural component of the Earth’s crust, generally found in trace quantities in all rock, soil, water and air. However, concentrations may be higher in certain areas due to either natural conditions or human activities.Many processes, including oil and gas, mining and other industries produce vast amounts of contaminated waste water that exceeds discharge or reuse parameters for this toxic element.As such current treatment often includes ion exchange technologies, membrane filtration or coagulation.This can be an expensive, time consuming treatment process.

 


The Solution

Ground Effects successfully treated a variety of waste streams, including process waters, produced waters, and mine waters that exceeded discharge and reuse criteria for arsenic.The EPT EOX technology can treat a variety of arsenic levels within the waste stream to below criteria. This allows the water to be available for reuse or discharge.

 


The Results

The EPT EOX treated waste waters removed arsenic contamination.

  • Viable solution for continuous treatment of a variety of waste water for the removal of all levels of arsenic contamination
  • Following treatment, the cleaned water can now be reused for irrigation in the area.
  • Reduced costs of chemical additives, labor associated with operations and maintenance.
  • Easily expanded for any size industrial waste stream
