Characteristics of two source water samples used in this study.

Source water I II
DOC (mg/L) 2.45a 3.00
UV254 (cm−1) 0.0335a 0.155a
SUVA (L/mg∙m)b 1.37 5.17
pH 6.87 8.50
Alkalinity (mg/L as CaCO3) 23.0a 90.0
Bromide (μg/L) 26.5a 2000
a

The dissolved organic carbon (DOC), UV absorbance at 254 nm, and bromide concentration were measured with a total organic carbon analyzer (Model TOC-Vcsh, Shimadzu), a UV/visible spectrophotometer (GE healthcare, Ultrospec 4300 pro), and an ion chromatograph (Dionex DX500), respectively; and the alkalinity was determined per the Standard Method (APHA et al., 2012).

b

Specific UV absorbance (SUVA) was calculated by dividing a sample’s UV254 absorbance (in cm−1) by the DOC concentration (in mg/L), and then multiplying by 100.
