Electrochemical solutions and water technologies for swimming pool chlorination - Water and Wastewater - Swimming Pools
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.
- 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
- 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
