ELECTROCHLORINATION SYSTEMS

TERSUS® Seawater Electrochlorination Systems, a reliable solution for marine and biological macro-fouling prevention. Our systems, featuring superior European-origin equipment, ensure energy-efficient, long-term operation. Utilizing state-of-the-art electrolyzer technology, we produce a safe, dilute solution of sodium hypochlorite in situ for direct injection into cooling water circuits. With a range of basic cell designs and a track record of successful projects in India and globally, we prioritize cost-effective, proven technologies in our product lineup.

is totally dissociated lo Na+ and Cl-; the following chemical and electrochemical reactions occur

  • Free chlorine is generated al the anode:
    2Cl- ==> Cl2 + 2e-
  • Hydrogen is evolved al the cathode with the corresponding formation of hydroxyl ion:
    2 H2O + 2e- ==> 2OH- + H2
  • Then chlorine and hydroxyl ions react chemically producing hypochlorite and chloride:
    2 OH- + Cl2 ==> ClO- + Cl- + H2O
  • The overall chemical reaction can be expressed as follows:
    2 NaOH + Cl2 NaClO + NaCl + H2O
  • Then chlorine and hydroxyl ions react chemically producing hypochlorite and chloride:
    2 OH- + Cl2 ==> ClO- + Cl- + H2O
  • The overall chemical reaction can be expressed as follows:
    2 NaOH + Cl2 NaClO + NaCl + H2O
  • Side reactions, both chemical and electrochemical, take place simultaneously with the basic reactions, such as the decomposition of hypochlorite to chloride, the anodic oxidation of hypochlorite lo chlorate (traces only), the cathodic reduction of hypochlorite lo chloride and the anodic evolution of oxygen. All these side reactions affect the current efficiency so that D.C. power required lo produce hypochlorite is actually higher than the theoretical one.
