Titanium anode for disinfecting swimming pool
Disinfection method: Sodium hypochlorite disinfection Disinfection principle: NaCl + H2O → NaClO + H2 ↑
Product Introduction
Product Description
Titanium anodes for sodium hypochlorite generators are specially designed electrodes used in saltwater swimming pool disinfection systems. These anodes eliminate the need for traditional chlorine chemical dosing by generating disinfecting chlorine compounds directly from dissolved salt in pool water.
The titanium anode is coated with mixed metal oxide (MMO) catalytic coatings, typically including:
Ruthenium oxide (RuO₂)
Iridium oxide (IrO₂)
Platinum-based oxide coatings
These coatings significantly improve electrochemical catalytic efficiency, corrosion resistance, and service life.
Working Principle
In saltwater chlorination systems, a small amount of salt (NaCl) is added to pool water. When water flows through the electrolytic cell, electrochemical reactions occur:
Electrochemical Reactions
Anode Reaction (Chlorine Generation):
2Cl⁻ − 2e → Cl₂
Cathode Reaction (Hydrogen Generation):
2H⁺ + 2e → H₂
Solution Reaction:
2NaOH + Cl₂ → NaCl + NaClO + H₂O
Overall Reaction:
NaCl + H₂O → NaClO + H₂↑
The generated products include:
Hypochlorous acid (HOCl)
Sodium hypochlorite (NaOCl)
These compounds effectively kill:
Bacteria
Algae
Pathogenic microorganisms
