How ​to ​remove/reduce ​bromoform ​concentrations ​from treated ​water?

Hello. Can anyone ​tell me how ​they have ​removed/reduced ​bromoform ​concentrations ​from treated ​water? The ​source is a ​borehole ​extracting 1MG/​L/D on an ​off shore ​island so ​bromide is ​already present ​in the raw ​water. The ​plant is ​unmanned and ​uses low ​bromide ​hypo ​solution as a ​disinfectant. ​  I have ​heard reverse osmosis or ion exchange is effective? Best regards, Roger
