Abstract
The article presents the results of the research on the influence of medium pressure UV lamp on the concentration of disinfection by-products (DBPs) in hot tub water. The lamp was installed in the water treatment system of the hot tub, located in the AGH swimming pool. The studies were conducted for 2 weeks. In the first week the lamp was switched off and water was treated by coag-ulation and pressure filtration on anthracite-sand filters after that disinfected with sodium hypo-chlorite. In the second week, treated water was additionally radiated by a medium pressure UV lamp, in an average dose of 205mJ/cm2. The water samples were taken every day from Monday to Friday. In these samples the concentration of the following parameters was measured: inorgan-ics chloramines and halogenated organic DBPs [trihalomethanes (THM), haloacetic acids (HAA), and chloral hydrate (CH)]. The research results showed that the application of medium pressure UV lamp efficiently decreases the concentration of chloramines, however, in regards to organic DBPs it may cause a significant increase in the concentration of CH. The concentration of THM and HAA increased statistically insignificantly.
