Original sentence: A combination of boiling at atmospheric pressure (i.Granular activated carbon filtering utilizes a form of activated carbon with a high surface area, and adsorbs many compounds including many toxic compounds.In the event that such UV treated water containing neutered microbes is exposed to visible light (specifically, wavelengths of light over 330-500 nm)  for any significant period of time, a process known as photoreactivation can take place, whereby there becomes a possibility for repairing the damage in the bacteria's reproduction DNA, potentially rendering them once more capable of reproducing and causing disease.Such iodine treated water is not suitable for the small percentage of the population allergic to iodine, a problem that also exists in using iodine based dyes for medical test radiography imaging.UV treated water must therefore not be exposed to visible light for any significant period of time after UV treatment, before consumption, to avoid ingesting reactivated and dangerous microbes
