The process comprises the steps of: (i) contacting the fluid with a particulate adsorbent material; (ii) allowing the adsorbent material to adsorb the chemical contaminant to produce a substantially purified fluid and a contaminant-carrying adsorbent material; (iii) separating the contaminant-carrying adsorbent material from the substantially purified fluid; (iv) contacting the contaminant-carrying adsorbent material with an aqueous slurry of a photocatalytic metal oxide powder in the presence of an electron acceptor and electromagnetic radiation in at least one of ultraviolet and visible regions; (v) allowing the contaminant to decompose to form a product which dissociates from the contaminant-carrying adsorbent to provide a regenerated adsorbent material, the aqueous slurry and the product; (vi) separating and recycling the regenerated adsorbent material to step (i); and (vii) recycling the aqueous slurry to step (iv). The process may be used to remove contaminants from and thereby purify fluids such as water, off-gases from air stripping processes and chimney gases.

Abstract: A fluid treatment system includes one or more radiation sources arranged in an irradiation zone within a treatment zone through which fluid to be treated passes and is irradiated. The irradiation zone has a closed cross section to maintain the fluid within a predefined maximum distance from the radiation source. Preferably, the irradiation zone comprises a reduced cross-sectional area perpendicular to the direction of fluid flow and thus the fluid flow velocity is increased through the irradiation zone. This allows the fluid to enter the treatment zone at relatively low speed, traverse the irradiation zone at high speed and exit the treatment zone again at relatively low speed to minimize the loss of hydraulic head throughout the system. Fluid entering the treatment zone passes through an inlet transition region wherein the cross-sectional area is reduced prior to entering the irradiation zone and fluid exiting the irradiation zone passes through an outlet transition region wherein the cross-sectional area is increased. Each transition region is designed to reduce hydraulic head losses as the fluid flow velocity is increased and decreased. In the irradiation zone, radiation sources are mounted on radiation modules which are arranged to provide improved accessibility for maintenance. The radiation modules may also be provided with cleaning assemblies which are operable to remove materials fouling the radiation sources in situ while the radiation sources are in the irradiation zone.

Abstract translation: 流体处理系统包括布置在处理区域内的照射区域中的一个或多个辐射源，通过该处理区域照射待处理的流体。 照射区域具有封闭的横截面，以将流体保持在与辐射源预定的最大距离内。 优选地，照射区域包括垂直于流体流动方向的减小的横截面面积，因此流体流速通过照射区域增加。 这允许流体以相对低的速度进入处理区域，以高速穿过照射区域，并以相对低的速度再次离开处理区域，以最小化整个系统中液压头的损失。 进入处理区的流体通过入口过渡区，其中在进入照射区之前横截面积减小，并且离开照射区的流体通过其横截面积增加的出口过渡区。 每个过渡区域被设计成随着流体流速的增加和减小而减小液压头损失。 在照射区域中，辐射源安装在辐射模块上，辐射模块被布置成提供改进的维护可达性。 辐射模块还可以设置有清洁组件，其可操作以在放射源处于照射区域的同时移除原位污染辐射源的材料。
