ABSTRACT:
A method and system for fluid purification is disclosed herein. In accordance with the present invention, an improved technique for recovering a decontaminated effluent after photocatalytic decontamination of a contaminated fluid is achieved. A slurry is formed by mixing a contaminated fluid with photocatalytic particles having an agglomeration property, and the photocatalytic particles are excited to render a treated slurry that includes a decontaminated fluid and the photocatalytic particles. The treated slurry is directed into a filter unit that includes at least one separation element. Each separation element has an inner surface defined by a channel extending through a substrate, and a plurality of pores which derive from the inner surface and extend through the substrate. The treated slurry is passed through the separation element and the agglomerated photocatalytic particles are allowed to form a layer at or near the inner surface of the separation element. Decontaminated effluent can then be recovered through the plurality of pores of the separation element. The treated slurry is preferably degassified in a tank before it is presented to the filter unit. Further, the amounts of recovered decontaminated effluent is preferably limited based on the level of treated slurry in the tank.
