Abstract
A total of 86 source water samples from 38 cities across major watersheds of China were collected for a bromide (Br−) survey, and the bromate (BrO3 −) formation potentials (BFPs) of 41 samples with Br− concentration >20 μg L−1 were evaluated using a batch ozonation reactor. Statistical analyses indicated that higher alkalinity, hardness, and pH of water samples could lead to higher BFPs, with alkalinity as the most important factor. Based on the survey data, a multiple linear regression (MLR) model including three parameters (alkalinity, ozone dose, and total organic carbon (TOC)) was established with a relatively good prediction performance (model selection criterion = 2.01, R 2 = 0.724), using logarithmic transformation of the variables. Furthermore, a contour plot was used to interpret the influence of alkalinity and TOC on BrO3 − formation with prediction accuracy as high as 71 %, suggesting that these two parameters, apart from ozone dosage, were the most important ones affecting the BFPs of source waters with Br− concentration >20 μg L−1. The model could be a useful tool for the prediction of the BFPs of source water.
