In-situ generating and dosing devices of biocides for drinking and swimming pool water treatment - Ozone
This document is applicable to devices for the generation and dosing of the biocide ozone. The ozone is generated in these devices according to the technology of dielectric barrier discharge. According to EN 1278 and EN 15074, ozone is suited for the use of the treatment of water intended for human consumption (drinking water), respectively for the treatment of swimming pool water. Ozone can be added to the water for disinfection and for oxidative purposes. This standard may be also applied for other technologies to generate ozone, e.g. electrolysis or UV irradiation, as far as reasonable or applicable. This standard specifies the devices construction, and test methods for the equipment used for in situ generation of ozone. It specifies requirements for instructions for installation, operation, maintenance, safety and for documentation to be provided with the product. The in situ generation of active substances, in particular ozone, is subject to the specifications of the Biocidal Products Regulation (EU) 528/2012 (BPR) [10]. The use of ozone for the purpose of disinfection/microbiological preservation of water requires compliance with the provisions of the BPR, in particular access by the user or his device manufacturer to a data set required for the authorization of ozone under the BPR.The in situ generation of ozone for the predominant purpose of oxidation of ingredients of water is subject to the specifications of the REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) [11] Regulation (EC) 1907/2006. The use for oxidative purposes requires access by the user to the data set provided for the authorization of ozone under REACH.
