Swimming Pool UV – Chloramine removal and disinfection

ULTRAAQUA Group is specialized in advanced pool water treatment and is known for pioneering particle filtration and disinfection technologies. The biggest problem in chlorinated swimming pool water is that chlorine reacts extremely rapidly with nitrogen compounds in the water to give rise to problematic disinfection by-products (DBP) such mono-, di-, and trichloramine. Especially, trichloramine, NCl3, has a very strong irritating effect on the eyes, nose, throat, and bronchial tubes. For several years now, Ultraaqua has focused R&D activities on dechlorination based on photocatalysis. Through this work, the most important processes and parameters have been identified. On the basis of this knowledge, the MultiRay pool water UV series has been developed. The key components of the MultiRay pool water UV-series are Medium-Pressure UV lamps and their adapted electronic lamp drivers. Gas filling and synthetic quartz composition results in the UV emission spectrum optimal for the degradation of chloramine fractions. An additional benefit of the individually fitted electronic high-frequency lamp drivers is market-leading Medium-Pressure UV-lamp lifetime of 9000 hours.  Furthermore, reactor geometries and electronic control systems have been designed to reduce operating costs to a minimum. Large flanged connections and body geometry results in very low head loss even at the max flow rate. The intelligent PLC control enables both automatic stepless lamp dimming and diurnal power variation. Both features add positively to ensure energy-efficient operation.

Material selection and components of high industrial quality guarantee long-term trouble-free operation in the often very hot, humid, and corrosive pool environments.
