SUVA is a measurement used in water treatment to assess organic matter content. Higher values indicate greater potential for disinfection byproduct formation during treatment.

SUVA (Specific Ultraviolet Absorbance) is a tool used by water treatment professionals to evaluate the nature of organic matter in water sources. It's calculated by dividing the UV absorbance at 254 nm by the dissolved organic carbon concentration. SUVA helps predict the likelihood of disinfection byproduct formation during chlorination. Higher SUVA values suggest more aromatic organic compounds, which are more reactive with chlorine. This measurement aids in optimizing treatment processes and ensuring safer drinking water.
