Electrocoagulation: Subtractive Technology Innovation

Increasing enforcement of Federal and State water quality standards has created the need for more advanced contaminant and filtration treatment methods. Traditional detention and filtration treatment methods are not able to typically perform to the enforced standards. WATERTECTONICS has developed an advanced technology that performs to the required standards.

WaveIonics

The WaveIonics™ electrocoagulation treatment system is an automated, non-chemical water treatment system operating between 100 to 1,000 gallons per minute (GPM) for the purpose of reducing or removing:

  • Heavy metals (Including but not limited to: Copper, Zinc, Lead, Arsenic, and Hexavalent Chromium)
  • Turbidity
  • TSS
  • Bacteria
  • Phosphorus
  • Oil De-emulsification
  • COD (Chemical Oxygen Demand)
  • BOD (Biochemical Oxygen Demand)
  • PCB's
  • Sulfides

WaveIonics™ Technology Principles

Electrocoagulation (EC) is an electrical process and has the capacity to destabilize emulsified oils, contaminants, metals, sub-micron particles. When contaminated water passes through the EC cells, the primarily negatively charged particles, combine with a positive charge from the cell plates, which initiates the coagulation process. The particles agglomerate into larger particles, no longer being suspended in the water column. Depending on the type of contaminant being removed, the agglomerated particles either rise to the top (oils) or settle to the bottom (sediment) of the water column.

EC is also a physiochemical process that consists of forcing contaminated water to flow between closely spaced metal plates, across which an alternating, direct or pulsing electrical potential is applied. As a result, contaminates such as Copper, Zinc and other fine particles which are primarily negatively charged, combine with a positive charge from the cell plates, which initiates the coagulation process. The particles agglomerate into larger particles, thus providing an opportunity for them to be filtered or removed.

Performance

The below table summarizes some recent performance reports on the WaveIonics electrocoagulation system. This data was collected from both in-house laboratory trials as well as in-field monitoring of existing systems. WATERTECTONICS invests considerable time and resources in research and development in order to ensure that their products are performing to the highest standards. New performance data will be updated here as it becomes available. If you are interested in performance of a contaminant that is not listed, please contact us for further information.
