Electrocoagulation for Better Removal of Contaminants

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 neutralizes 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.
