In a nutshell, it is based on a central disinfection system with electrochemical hydrolysis, UV and copper ionisation, combined with a carbon-pH-mineralising technique, all controlled by a central control unit.
No, we can manufacture this system at a price which is the same as a traditional chlorine and acid installation. So no need to spend your money on a high chlorine system!
For your safety, in the context of public pools, you always need a basic disinfection capacity with chlorine. Just imagine what happens when 50 children jump into the water at once. Chlorine is a strong disinfectant and is also used for the safety of drinking water. So, the question is not whether chlorine is needed but how much chlorine is needed.
NoviNato has a ‘compact eco module’ in development for 50-100m³ pools. This is the market of the large private pools, pools at hotels, wellness centers, resorts, therapy pools and small private swimming schools.
The following graph shows the values in a busy recreational pool with rapids, wave pool, waterfalls, fountains, etc. with highly fluctuating occupancy. At off-peak times there are only 10 swimmers, at peak times 100. Let’s briefly review how the system automatically adapts to the number of visitors on a Saturday. When more visitors come, the free available chlorine is bound and new chlorine needs to be administered which causes the pH to increase. If in the graph the pH rises, this is because new chlorine is administered because more pollution enters the water via the visitors.
- The system automatically adapts to the additional occupancy.
- The free available chlorine level drops to a maximum of 0.25ppm, remaining safely above the lower limit.
- At the peak moment there is temporarily 0.37ppm, but after 30 minutes this has already dropped back to 0.28ppm.
- The pH does not go above 7.18.
This is an installation where gases, liquids and solids can be dissolved in a tank and then added to the pool water. Part of the swimming pool water is diverted to a tank in which various additions take place. Carbon is injected as a gas into the holding tank to bring the pH to the right level and keep it there. The CO2 we use is ‘recovered CO2’. This means that the CO2 released from industrial processes is not blown into the air, but collected, pressed into tanks and then taken to the swimming pool for pH correction. The Carbon mineraliser makes it possible to use CO2 to correct pH and achieve a positive mineral content (bicarbonate). This makes the composition of the pool water suitable for low chlorine swimming in all public swimming pools.
The Carbon mineraliser is available as a plug and play model. It can therefore be installed in any technical room to replace sulphuric acid. With the Carbon mineraliser, the chlorine content can already be reduced to a range of 0.50 -0.60ppm. That’s already half the traditional value.
For many pools, renovation is the most budget-friendly solution. This can be done in steps, taking into account the short and long-term budget. The first step is the installation of the Carbon mineraliser. The second step, a few years later, is the installation of the OXY-3 system. The final step is the installation of the complete control system of AquaNovi. This way of working offers budget-friendly possibilities.
