The treatment of swimming and bathing pool water in the public sector is regulated in Germany by the DIN 19643 series of standards. Since April 2021, the ozone-bromine process has been described as Part 5 in the set of standards. The initiator for the standardisation application was the company Hydro-Elektrik GmbH, which founded the path of chlorine-free bathing water treatment more than 40 years ago and has continuously developed the process in practice. The results of this development are the optimised HYDROZON® compact filter systems, which are produced in Germany and successfully used in private and public baths.
With a treatment capacity of 10 to 75 m³/h, the P30 and H30 series produce chlorine-free, fresh and hygienically perfect feel-good water in small pools, whirlpools and water playgrounds up to therapy and large swimming pools. For higher treatment capacities, several systems are operated in parallel.
For the first time, an alternative option for bathing water disinfection, bromine, has been included in the regulations. The basis of the process combination is the formation of free bromine (hypobromous acid) through ozonation of water containing bromide. For more information, see here:
