Technology used: Electrocoagulation
Electrocoagulation is a water treatment process whereby an electric current is applied across metal anodes to remove various contaminants from water. The metal cations dissolved in the wastewater are complexed to form hydroxide ions, and these compounds act as a coagulant. By controlling the amperage, the coagulant dosage can be adjusted to meet the treatment goals. Although the electrocoagulation mechanism resembles chemical coagulation, some differences benefit electrocoagulation. Indeed, electrocoagulated flocs differ from those generated by chemical coagulation. Flocs created with the electrocoagulation process tend to contain less bound water, are generally more resistant to shearing and are typically more easily filterable.
