Electro Chemical Reaction in Scale Remover Reactor

Reactor of ElSr increases the pH of the water to 8.2-8.7, and uses the chemical reactions caused by electrolysis to produce oxidants with powerful bactericide effect, preventing corrosion and eliminating bacteria. OH+ ions that remain near the anodes cause a decrease of pH levels and produce oxidants which disinfect the water.

Scale available in the Cooling tower reservoir is composed of sodium and chloride. When DC is passed through the reactor to the electrolyte (water), the chlorides will disassociate and form chlorine.

Electrolysis occur in an undivided cell when a DC current is passed through a saline water 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) instant aneously. The overall reaction, sustained by electrical energy, is as,

 2Nacl (salt) + H2O (water) NaOCl (hypo) +NaCl (salt) + H2 (Hydrogen).
