Through the discussion from a view different from the traditional

the correlations between UV 254 and organic matter monitoring parameters in the field of water supply and wastewater treatment was discussed

such as TOC

DOC and THMs precursors. According to the explanation of applicability in this paper

UV 254 can be used as a surrogate parameter. The measurement of UV 254 as a surrogate parameter has several advantages

such as inexpensive instrument

convenient operation

low operating costs

good correlations to the parameters surrogated

high accuracy and excellent data reappearance in multiple measurements. The application of UV 254 as an indirect parameter is quite valuable

especially under the current financial level of the operation and monitoring of the water and wastewater treatment plants and the laboratory research in China.
