A new technique using ozone loaded on adsorbents for industrial waste-water treatment has been investigated. This is a three-step process: ozone adsorption on a fixed bed column; water treatment on the bed loaded with ozone; and finally drying/ regeneration of the wet bed. Silica gel of mean particle size of 1.5 mm has been tested for ozone loading capacities followed by water treatment, both at ambient temperature. The mechanisms of the mass transfer process during ozone loading and water treatment have been established. The drying of the adsorbent using vacuum and dry air is feasible, but it is a time-consuming operation. A design procedure is described for the whole system.
