Assessment of factors affecting bromate formation in drinking water bottles

摘要

This paper presents the results of experimental study conducted to investigate the effects of different parameters on bromate formation in bottles of drinking water. The effects of various temperatures, storage times, pH and some water quality parameters including bromide, total organic carbon (TOC) and total dissolved solids (TDS) were investigated. Three different regional and international water bottles brands available in the United Arab Emirates (UAE) were selected. For each brand 36 polyethylene terephthalate (PET) bottles of water were used for the experimental study. It is concluded that the effects of storage time and temperature was negligible for all brands and that the effects of pH levels on bromate formation was noticeable. Increasing pH level increases the bromate formation for brands X and Y but decreases the bromate formation for brand Z. It is also concluded the effect of TDS, TOC and turbidity on bromate formation was not significant.
