Legionella Control in Water Installations

In 2009 a Spa Hotel (built in 1982) with 160 rooms in 4 floors was reconstructed against Legionella with a BlueBox after our planning and consultation. Both the hot water and the cold water is disinfected with electrolytic on-site produced sodium hypochlorite. Through the permanent low disinfection with 0.3 mg/L the problem of Legionella has been solved since then.
