美国的饮用水法规草案将规定溴酸盐离子（BrO3-）的最高污染物水平（MCL）为10 ug/L，溴酸盐离子是饮用水处理过程中产生的臭氧氧化副产物。已经评估了几种不同的去除三氧化二硼的方法:亚铁还原法（Fe2+）、活性炭表面还原法（GAC）和紫外线照射法（UV），这些方法在三氧化二硼形成后适用于考虑在不同应用点使用臭氧的传统饮用水处理厂。 在所有过程中，对处理后的水进行的化学分析表明，溴离子（Br-）的形成表明，化学还原BrO3-是重要的机理；铁絮体表面对溴的吸附不明显。BrO3-的去除是活性炭特有的，并非所有的碳都能将BrO3-还原为Br-。

Draft drinking water regulations in the US will specify a maximum contaminant level (MCL) of 10 ug/L for bromate ion (BrO3-), an ozonation byproduct produced during drinking water treatment. Several different options to remove BrO3- after its formation, applicable to conventional drinking water treatment plants contemplating the use of ozone at various points of application, have been evaluated: ferrous iron reduction (Fe2+), activated carbon surface reduction (GAC), and ultraviolet irradiation (UV). In all processes, chemical analysis of the treated water showed the formation of bromide ion (Br-) indicating that chemical reduction of BrO3- is the significant mechanism; adsorption of BrO3- onto the surface of iron floc is insignificant. BrO3- removal is activated carbon specific, and not all carbons have shown the ability to reduce BrO3- to Br-.
