Regulation instrumentation

Swimming pool water contains pathogenic and non-pathogenic microorganisms that are a risk to human health, and therefore requires a balanced chemical treatment to minimise the microbiological risk. The standard UNI 10637:2016, provides some specific requirements regarding the measurement and regulation of disinfection treatments for classes A, B and C (facilities for public use), while UNI EN 10713 indicates the requirements for class D (facilities for private use). The disinfection treatment is carried out by dosing substances, which are regulated on a regional basis.

Equipment intended for pH measurement and control (type A, B, C range 4.5-8.5pH; type D range 6.8-7.6pH) must have an output signal to drive the dosing systems and for type A pools proportional control is preferred.

FIP M9.00 series monitors combined with 200 series pH electrodes are the ideal solution to meet these requirements. The RedOx potential measurement equipment can be used in D-type pools to monitor the evolution of organic pollution in the pool water and to control dosing equipment for disinfectants (RedOx >650mV). M9.00 series FIP monitors combined with 200 series ORP sensors provide an optimum compromise between simplicity and reliability. For classes A, B and C, however, free chlorine readings (Cl2 range 0.6-5mg/I) are required. The CLF6 series sensors, which can be combined with pH measuring instruments in case of significant variations, fully comply with this requirement. For more modern plants using Chlorine Dioxide for chlorination, also with in-situ production systems, FIP also offers the CLD6 series amperometric sensor range, dedicated to the direct measurement of this parameter.
