To date, there has been extensive research on decreasing THM
concentration in drinking water, such as normal water treatments
(adsorption, ozonation, or enhanced coagulation) and advanced
technologies like reverse osmosis (RO). In previous studies, activated
carbon (AC) has been widely applied to adsorb simulated
THM-containing water due to its large surface area and great
adsorption ability [9]. However, it could not remove brominated
compounds more efficiently, resulting in an increasing ratio of brominated
disinfection by-products. AC also failed to degrade THMs
into mineralized products (i.e. CH4 and water). Previous studies
have mostly focused on eliminating THM precursors [10,11]. However,
the formed THMs still pose a threat to human health and the
cost of AC treatment is relatively high compared to physicochemical
methods.
