Adjustment instrumentation

Swimming pool water contains pathogenic and non-pathogenic microorganisms, which are hazardous to human health, and therefore requires a balanced chemical treatment to minimize microbiological risk. The UNI 10637: 2016 standard provides for some specific requirements regarding the measurement and regulation of disinfection treatments for classes A, B and C (systems for collective use), while UNI EN 10713 indicates the requirements for class D (systems for private use). The disinfection treatment takes place through the dosage of substances, regulated on a regional basis.

The equipment intended for the measurement and regulation of pH (type A, B, C range 4.5-8.5pH; type D range 6.8-7.6pH) and the representative parameter of disinfection, must have an output signal to drive the dosing systems, in particular for type A pools proportional regulation is preferred.

The FIP M9.00 series monitors, for type A, B and C systems, combined with the CLF6 series sensors and, in case of significant variations in the pH value, with the pH electrodes series 200, fully comply with this requirement which provides for the concentration of free chlorine between 0, 6 and 5 mg / l.

For the most modern plants that use chlorine dioxide for chlorination, even with in situ production systems, Aliaxis also offers the CLD6 series range of amperometric sensors, dedicated to the direct measurement of this parameter without the need to combine it with pH monitoring.

For type D plants, the pH and ORP 200 series electrodes can be used to monitor the evolution of organic pollution of the tank water and to drive the dosing equipment of disinfectant substances (RedOx >650mV).
