SWIMMING POOL DE-CHLORAMINATION UV SYSTEMS

ULTRAAQUA UV medium-pressure (MP) systems are designed and optimized for disinfection and chloramine reduction in swimming pools. Scientific research conducted over the last 10 years has shown that during normal operation of a swimming pool the majority of the combined chlorine measured is composed of organic chloramine compounds.

Based on this knowledge, ULTRAAQUA has conducted research into developing dedicated medium pressure UV lamps and reactors. They maintain a low level of organic combined chlorine from swimming pool water through continuous photolysis. By synthesizing organic chloramines from the majority of the nitrogen precursors introduced into swimming pool water, ULTRAAQUA has conducted experimental investigations and process modeling studies. They have quantified the photolysis process in the MP UV reactors providing proprietary kinetic data for photolysis of several organic combined chlorine compounds.

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 a high flow rate. The intelligent PLC control enables both automatic 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.
