ELCAT™- non biodegradable and toxic wastewater treatment

ELCAT Stage 1

Electrochemically treats wastewater in electrolyzer with insoluble electrodes under anodic polarization

     • Easily oxidizable compounds are treated

• Chloride ions (Cl-) in the wastewater form Cl2 which in turn forms the strong oxidizing agents (hypochlorite and hypochlorous acid)

Cl2 + H2O HClO + H+ + Cl-

HClO + OH- ClO- + H2O

• Electrochemically generated ClO- and HClO oxidize wastewater pollutants (R-H)

• This cycle is repeated resulting in high efficiency oxidation and in a very short time

ELCAT Stage 2

Enhances treatment and provides dechlorination

• Metal oxide catalytic decomposition of ClO- and HClO occurs and free radicals (ClO-, Cl-, OH- and O-) form

• Dechlorination occurs through reduction of ClO- and HClO

• Final polishing occurs through reaction of the free radicals with remaining oxidizable substances

ELCAT Applications

• Herbicides
• Insecticides
• Textiles
• Organic dyes
• Phenols
• Ammonium
• Polishing

ELCAT™ is currently installed in several industrial wastewater treatment facilities in chemical, food and textile industries.

Typical removal efficiencies of waste constituents are:
