The challenge
In the Bernsbach outdoor pool, a chlorine granulate system and sand filter technology were used for water treatment. Both needed to be replaced, and the search was on for modern, efficient technology. The operators wanted to use non-hazardous table salt with electrolysis for disinfection. They were also looking for a filter technology that generates low wastewater costs and can be installed in a space-saving manner.
The solution
All of these issues can be solved using OSEC® B-Pak chlorine electrolysis systems and a Defender® filter. This meant the following points could be improved:
- Space-saving filter process with low wastewater costs
- Sustainable and reliable disinfection process
- Avoidance of hazardous substances, as the operator only has to handle common salt
The electrolysis system is controlled by the measurement and control system DEPOLOX® Pool Compact, which has proven its suitability in many pools in Germany on a daily basis.
The premises hardly had to be adapted for the conversion, as both the electrolysis system and the Defender® filter are very compact and clearly laid out. A compact, load-dependent adjustable Wafer® type UV system with a flange distance of only 16 cm was installed to minimize chloramines. A dosing station for sodium bicarbonate was also installed to ensure compliance with the acid capacity parameters.
