Electrocoagulation for Better Removal of Contaminants

Share |

Electrocoagulation TiECCR is a process that destabilizes suspended or dissolved contaminants by passing electrical current into the medium. After reaction the compounds or the elements reached the maximum stable state. At the stable conditions, solid is produced that is less colloidal and emulsified. Once this stage is reached, the contaminants that form hydrophobic entities precipitate out that can be removed easily by various secondary techniques or treatment.

Electrocoagulation often neutraliz es charges of the particles or ions which allows precipitation of contaminants and replaces the use of expensive chemical agents. These reactions can be explained as follows:

Within the electrocoagulation chamber, oxidation and reduction reactions are forced to their natural end point thereby speeding up the natural process of nature.
pH that is induced by electrocoagulation chamber is swing towards alkalinity
The presence of electron in the water prevents the polar effect of the water complex which allows the colloidal materials to precipitate. The osmotic pressure that is created by the electron presence results in the destruction of bacteria, viruses and cysts.
Water is separated from pesticides, herbicides, chlorinated PCB's by the action of halogens.
Oxygen ions used for bleaching oxidizes dyes, cyanides, bacteria, viruses, bio hazards etc.
The emulsion breaking results in the separation of water from oil, drillers mud, dyes, inks etc.

Advantages:

Advantages of TiECCR are as follows:

Cost effective
Cost of operation is low
Cost of maintenance is low
Sludge is minimized to a considerable level.
Power required is low
No chemical addition is required
Treatment is instantaneous
Space requirement is less
Pathogens can be disinfected effectively.

Applications

TiECCR applications include:

For dewatering sludge
Useful in dye and textile industry
Useful in cleaning ground water
Used in cooling towers of various industries.
Removes radioactive isotopes
Treats industrial wastewater
Used for pre-treatment of water for various membrane separation process like RO, UF, NF.
Boiler make up water for pre-treatment.
Wastewater disinfection
