    • Recreational or process water can be treated by uniformly dissolving in the water a singlet oxygen-generating photosensitizer selected from the group consisting of condensed aromatic compounds, acridine dyes, coumarin dyes, crystal violet, fluorene derivatives, porphyrin derivatives, chlorins, thiazine dyes, thioketones, xanthene dyes, or by uniformly dissolving in the water a singlet oxygen-generating photosensitizer having an absorption maximum less than 659 nm and sufficiently strong coloration so that the presence of the photosensitizer can be visually detected in the water. Exposure of the photosensitizer and ambient or added oxygen to sufficient light or other activating energy causes the generation of singlet oxygen and the destruction or control of microorganisms.
