The luxurious pool experience
Say goodbye to chlorine odors, irritated eyes, hair damage and faded swimsuits caused by excessive disinfection by-products and over chlorination. Common salt and electricity generate a consistent and proper amount of pure chlorine solution in a safe, simple and cost effective way to disinfect pools.
We are committed to improving your recreational water quality, while using a green, recyclable treatment process.
Benefits of Salt Chlorination
- Pool water has a silky, luxurious feel for the optimum swimming experience
- Consistent generation of chlorine disinfectant helps prevent chlorine spikes or algae episodes
- Minimized maintenance with many automated systems available
- Reduced chemical storage and handling
- Typical 3-5 year chlorinator lifetimes means fewer trips to the pool store since the disinfectant is made on-site
- Naturally recycling process uses simple salt to generate the disinfectant
Since the 1970’s, we offered solutionsfor salt water pool chlorination, from the initial static polarity technology to the self-cleaning product based on current reversal technology. In 1982, the first specific DSA® electrode for pools application was manufactured, and has shown outstanding performance ever since making it the most validated anode in the field to date.
De Nora DSA® electrode for swimming pool electrochlorination is a specialized technology found in all major swimming pool equipment manufacturers worldwide. The versatility of the product allows for use in residential, spa and commercial applications.
Recommended Operating Conditions:
- Salt (sodium chloride) range of 2-6 g/L
- Water temperature: 15-40°C
- Follow national standards for pool chemistry including disinfectant levels and saturation index parameters
- Stabilizer levels of 30-50 ppm for outdoor facilities
De Nora DSA® Electrode Advantages
- Validated and reliable electrochemical technology for pool water disinfection
- De Nora has the longest experience in electrode catalyst coating development
- Significant resources committed to continuous product improvement
- Self-cleaning product designed specifically for pool use
- When the salt chlorinator is energized, the electrodes catalyze reactions with the sodium chloride and water molecules at the anode and cathode surfaces to generate the chlorine disinfectant
- Chlorine is in the form of hypochlorous acid and sodium hypochlorite in the pool water, and the ratio of the two is pH dependent
- When the chlorine disinfectant kills or inactivates pathogens and oxidizes organics/contaminants, the chlorine returns to the native state as salt (NaCl) in water as a recycling process
Overall Chemistry Reaction:
NaCl + H2O + electricity --> NaOCl (disinfectant)
Primary Anode Reaction: 2 Cl- - 2 e- ⇒ Cl2
Primary Cathode Reaction: 2H2O + 2 e- ⇒ H2 + 2 OH-
