WHY & WHAT
Why Tiaano™ ECU?
On-site Chlorine Generator is the preferred water disinfection and or anti-biofouling equation, if compared with Gaseous chlorine and Commercial hypo. The potential risks associated with the Bulk transport, bulk storage and handling of hazardous chemicals (gaseous chlorine & commercial hypo) are totally eliminated with Tiaano™ on-site electrochlorination system. It is the preferred substitute, most sensible option when considering Economy, Safety, Convenience and Environmental Protection. Refer the Costing of Tiaano™ ECU
What is Electrochlorination?
Electrochlorination is an electrolysis process where; either natural seawater or an artificial brine solution (fresh water + salt) is converted into sodium hypochlorite solution.

Salt is composed of sodium and chloride. When DC (direct current) is passed through titanium electrodes to the electrolyte, the chlorides will disassociate to form chlorine. The process is basically as follows:

  • Electrolysis occur in an undivided cell when a DC current is passed through a saline water solution (e.g. seawater or brine solution)
  • At the anode: Oxidation of chloride ions to produce chlorine (Cl2)
  • At the cathode: Reduction of water to produce sodium hydroxide (NaOH) and hydrogen (H2)
  • Liberated chlorine reacts with the sodium hydroxide to produce sodium hypochlorite (NaOCl) instantaneously
  • The overall reaction, sustained by electrical energy, is as follows:

2NaCl (salt) + H2O (water) ---> NaOCl (hypo) + NaCl (salt) + H2 (hydrogen)
What is Sodium Hypochlorite?
Sodium hypochlorite, “NaOCl” (also known as “hypo”, “bleach”, or “liquid chlorine”), is a powerful oxidant that is used world-wide for the chlorination of water for:

  • Anti-biofouling (e.g. to prevent sliming, mussel/barnacle growth, etc)
  • Disinfection (e.g. for drinking water, general anti-bacterial purposes in process water, etc)
  • Chemical treatment (e.g. bleaching, removal of iron, manganese, etc)
