Project Number # 1144
Project Leader: Qin Li
Brominated disinfection by-products (DBPs), including bromate, bromodichloromethane, chlorodibromomethane, bromoform, bromoacetic acid, dibromoacetic acid, are strictly regulated. Brominated DBPs are 10 - 104
times more toxic than their chlorinated counterparts. Brominated-DBPs are a major concern commonly encountered where raw water intakes have elevated levels of bromides (Br-). The issue of brominated-DBP formation is
further exacerbated by the effects of climate change, such as increased frequency of extreme events, altered nutrient loading from catchments, and deterioration of source water quality. Therefore, managing bromides in
drinking water treatment has profound significance for achieving the primary target of water utilities, that is to provide safe drinking water.
The aim of this lead project is to identify a feasible and robust treatment method for minimising brominated disinfection-by-products.
