Abstract: A method and apparatus for adsorbing perchlorate in a fluid and successively destroying it. Perchlorate in the fluid is removed by adsorption on an adsorbent in a column. The adsorbent is then regenerated by desorbing perchlorate, and the perchlorate in the regenerant is then chemically destroyed.

Abstract: An apparatus for reducing a concentration of ions of perchlorate in water. In one implementation, the apparatus includes an ultraviolet (UV) light source, and a reactor chamber to operate a fluidized bed of suspended iron particles. The reactor chamber facilitates UV light into the reactor chamber from the UV light source, in which the UV light is a catalyst for removing perchlorate ions. The apparatus includes a recirculation tank to use water and/or iron recirculated with the reactor chamber. Another implementation involves a thin-film reactor for the water and iron particles, in which the thin-film reactor is configured for the water to flow over a surface and mix with iron particles. The thin-film reactor implementation includes a separator apparatus to separate iron particles from the water, and an ultraviolet lamp to apply ultraviolet light to the water in the thin film reactor.
